Pearl of Hamilton Standard Prop. The shape of the seal groove is unimportant as long as it results in proper compression of the seal between the bottom of the groove and the cylinder wall. H. Moving seals that pass over ports or surface irregularities while under hydraulic pressure are very quickly cut or worn to failure. The rubber absorbs the stack-up of tolerances of the unit and its internal memory maintains the sealed condition.

Figure 1-6 shows the O-ring at its pressure limit with a small portion of the seal material entering the narrow gap between inner and outer members of the gland.E. The surface tension of the elastomer is no longer sufficient to resist flow and the material extrudes (flows) into the open passage or clearance gap. a paper presented at the S. Note that the O-ring has been forced to flow up to. The seals can be made to seal satisfactorily between reciprocating pistons and cylinders at any fluid pressure up to 5000 psi. In either static or dynamic O-ring seals under high pressure the primary cause of seal failure is extrusion of the seal material into the piston-cylinder clearance. D. soldering. The O-ring seal falls in the latter class. 1. This compression may cause the seal to roll slightly in its groove under certain conditions of piston motion. Therefore. 1947 by Mr. brazing. G. D. O-ring seals must be radially compressed between the bottom of the seal groove and the cylinder wall for proper sealing action. A. this extremely viscous fluid is forced to flow within the gland to produce “zero clearance” or block to the flow of the less viscous fluid being sealed. before the application of pressure. The major factors effecting extrusion are fluid pressure. E. Annual Meeting.A. F.4 Operation All robust seals are characterized by the absence of any pathway by which fluid or gas might escape. the contacting surfaces should be polished for long seal life. A single O-ring will seal with pressure applied alternately on one side and then on the other. The seal material under mechanical pressure extrudes into the microfine grooves of the gland. Parker Hannifin Corporation • O-Ring Division 2360 Palumbo Drive. (Limit of test pressure). and provides room for the compressed material to flow so that the seal is not solidly confined between metal surfaces. The rubber seal should be considered as essentially an incompressible. but in cases of severe loading or usage under necessarily unfavorable conditions. C.com 1-3 . Seals may be arranged in series as a safety measure but the first seal exposed to pressure will take the full load. The seals can be made perfectly leak-proof for cases of static pistons and cylinders for fluid pressures up to 5000 psi. Whether by mechanical pressure from the surrounding structure or by pressure transmitted through hydraulic fluid. KY 40509 Phone: (859) 269-2351 • Fax: (859) 335-5128 www. O-rings can be used between rotating members with similar results but in all cases the surface rubbing speed must be kept low.

Static seals will seal at high pressure in spite of slightly irregular sealing surfaces and slight cuts or chips in the seals. Even when broken or worn excessively.6 Limitations of O-Ring Use Again citing Mr.7 Scope of O-Ring Use Further discussion in this chapter and in the remainder of this handbook is based on specific types of O-ring seals and special applications.

Examples of a seat-seal include O-ring as a “washer” on the face of a spiral threaded valve. or sealing surface at the O-ring. the mating gland parts are not subject to relative movement (except for small thermal expansion or separation by fluid pressure). This motion tends to rotate one or the other member in relation to the O-ring.< Back Section Contents Parker O-Ring Handbook Table of Contents Search Next > 1. as contrasted from seals in which one of the gland parts has movement relative to the other.5 Seat Seals In a seat seal. 1. for complete identification.com 1-5 . as in multiple turns to operate a valve handle. or a wheel on a fixed axle.

Note that the seal should be defined as “pneumatic-rotary” etc. a plunger entering a chamber. a seal at a pipe or tubing connection. Figure 1-9 illustrates a typical reciprocating seal.1 Static Seals In a truly static seal. the return arc in the opposite direction distinguishes the oscillating seal from a rotary seal.7. Lexington. An example of an oscillating seal is an O-ring seal for a faucet valve stem. This motion tends to slide or roll the O-ring. See Figure 1-11.7.7. Consult a Parker Territory Sales Manager for more information on special seals to meet this requirement. This has a vital affect on the lubrication of the O-ring and thus influences all moving (or dynamic) seal installations. The motion of closing the passage distorts the O-ring mechanically to create the seal. A sub-classification is closure with impact as compared with non-impact closure. the O-ring serves to close a flow passage as one of the contact members.7. Note: True static seals are generally quite rare. Examples of a rotary seal include sealing a motor or engine shaft. This applies when rotation is reversible. and a hydraulic actuator with the piston rod anchored. Figure1-8 illustrates a typical static seal. a seal under a cover plate. 1.

However. However. Low pressures require a soft material that can be easily deformed as it is forced against mating surfaces. The flatness will gradually disappear and the seal will regain its original resilience upon warming. especially for dynamic applications. Flexibility. along with volume and compression set changes as mentioned above. The swelling or shrinkage effect of the fluid being sealed must also be taken into account. It may become stiff at a temperature 2°C to 5°C (5°F to 10°F) higher than that at which it is rated. low temperature hardness increase is seldom of consequence. The first effect of increased temperature is to soften the compound.12 Thermal Effects All rubber is subject to deterioration at high temperature. the tendency is to overlook the effects of low temperatures on elastomeric seal compounds as they are generally reversible as the temperature rises. If the seal swells. these changes are not reversible. From experience. Lexington. it may take two or three months for a compound to crystallize at a low or moderate temperature. not only for assuring low temperature performance but occasionally as a quality assurance measure as well. as stated. it is absorbing fluids which may act in much the same way as a low temperature plasticizer. Being chemical in nature. the same type of compound with 40 durometer hardness at room temperature may register only 75 durometer at -34°C (-30°F) and provide somewhat better response. hardness is only one of several factors to consider when low temperature performance is involved. In moderate pressure service. the seal may now lose some of its original flexibility at low temperature. resilience. we have found that most compounds will provide effective sealing at 8°C (15°F) below their TR-10 temperature values. hardness should be considered along with the low temperature properties of the compound. The greater part of the leached material is usually the plasticizer provided by the compounder for low temperature flexibility. but there does not seem to be much correlation among them.

With the exception of the cryogenics field. Volume change and compression set are both greatly influenced by heat. It is significant that many of the materials for which hardness is plotted in Figure 2-18 are considered good for seal service at temperatures considerably below that at which durometer hardness tends to reach a maximum. compression set and brittleness are perhaps more basic criteria for sealing at low temperature than measured hardness. hardness increases. are reversible. Hardness is influenced in a rather complex way. If low pressures are anticipated at low temperature. When a compound crystallizes it becomes rigid and has none of the resilience that is so necessary for an effective seal. Any changes induced by low temperature are primarily physical and. Perhaps the best of the low temperature tests is TR-10 or Temperature Retraction Test. These generally cause an increase in hardness. It is possible that a 70 durometer compound at room temperature might harden to 85 durometer at -34°C (-30°F) and fail to respond to low pressure at this temperature. However. and will reverse when the temperature drops. On the other hand. something is being extracted from the compound. An elastomer will almost completely regain its original properties when warmed. However.4. Initially. With increasing time at high temperature. This phenomenon manifests itself as a flat spot on the O-ring and is sometimes misinterpreted as compression set. If the seal shrinks. This is a physical change. allowing the seal to remain more flexible at low temperature than was possible before the absorption of the fluid. Changes in tensile strength and elongation are also involved.

(Crystallization is the re-orientation of molecular segments causing a change of properties in the compound). it must be considered in high pressure applications because a compound that is sufficiently hard to resist extrusion at room temperature may begin to flow and extrude through the clearance gap as the temperature rises.parkerorings. This may be demonstrated by reference to Figure 2-18 that shows the variation in hardness for several elastomers at low temperatures.

A large percentage of the sulfur under the influence of heat (vulcanization) forms bridges (crosslinks) between the elastomer molecule chains.4. and that the more a seal is compressed. It is very difficult to say how far electrochemical corrosion depends on the elastomer. ECO. The propensity to corrode depends on the type of metal alloy(s).4. Conversely. Reasonable resilience is vital to a moving seal. It is not to be confused with reversible or temporary property losses.

If not. and no problems should arise. Minor Pioneering applies when only a slight departure from previous practice is involved. 2. Since non-pioneering applications will include the greater part of all design work normally encountered. It is fortunate that major engineering problems constitute only a very small percentage of the total work. 2. the same compounds utilized in past design may be trusted to give successful results. There is a third case of “non-pioneering design” in which the designer can use past successes of others as a basis for a design foreign to his own experience. B. If no pioneering were ever encountered. the answer is at hand. Each foregoing category is based on successful practice under similar service conditions. For such design conditions. established by widespread field contact developed from years of experience with O-rings. many stock compounds have proven to be very satisfactory in certain fluids when used in glands of normal design.2 Pioneering Design This implies that there is something new and therefore unknown or at least unproven about the design.parkerorings. and operating conditions.

KY 40509 Phone: (859) 269-2351 • Fax: (859) 335-5128 www. c. temperatures and test fluids for accelerated tests can be found in ASTM D471. and good recovery from peak loads. 70 hours at 100°C (212°F).20 (for example: 69 Bar x 1.18. Lexington. Thus the first step is to set the original physical property limits that will assure that the mechanical properties desired in the seal are present.” This value will then be used in the control section..) and (c.18 Qualification Testing Functional requirements should always be given first.5 to 62. A reasonable plus or minus limit is usually set as insurance against excessive deterioration and early seal failure. Where feasible.1 Bar (500 to 900 psi). A standard ±5 point tolerance is established to allow the vendor a realistic working range and permit normal variations experienced in reading durometer.20 = 1200 psi)). Always take into consideration the inherent strength of the elastomers most likely to be used to meet the specification (most silicones have tensile strengths in the range of 34. Tensile Strength Determine the minimum tensile strength necessary for the application. it would be foolhardy to specify a minimum tensile strength requirement of 138 Bar (2. This fluid variation accounts for some of the differences in test results. can be expected to lose a maximum of 35% tensile strength and the same compound tested in MIL-L-7808 (di-ester base fluid) can be expected to lose a maximum of 70% tensile strength.Modulus Choose a minimum modulus that will assure a good state of cure. a. It provides for the normal tensile strength variation of ±15% experienced between production batches of a compound. and leakage). a 10% tolerance is never considered realistic since this much variance in tensile strength can be experienced on two test specimens cut from the same sample. . Although these two sections may be combined in the actual specification.parkerorings. however. 65. Every well-written specification should contain both qualification and control sections.e. chemical or physical results.8 Bar (1. 3). multiply it by 1.000 psi x 1.25 to allow a safety factor and to provide for normal production variation of ±20%.18. Modulus is directly related to these two properties.1 Original Physical Properties Original Physical Properties (before exposure to service conditions) are those measurable attributes of an elastomer formulation which define certain physical parameters used in determining the suitability of a given elastomer material for a given class of service. This does. b. Once the minimum tensile strength has been set. 70. 2. Recommended times. These are in addition to the functional tests. Experience will probably dictate the limits.000 psi) for a silicone material). a nitrile compound tested in petroleum based IRM 903 (formerly ASTM oil No. 85). designate a standard test method for each test required by a specification (either ASTM or ISO Test Method). These properties are: a. For example. at 100°C (212°F). Determine the durometer best suited for the application and round off (50. The following discussion will lead to a specification for qualification of new seal compounds after the known functional requirements appear to correlate with field or laboratory. adhering to the procedures described above minimizes this problem. 2-30 Parker Hannifin Corporation • O-Ring Division 2360 Palumbo Drive. These methods are widely used and help to assure correlation among laboratories. Original Physical Properties are also used in limiting/delimiting rubber specifications. Hardness Change This is usually controlled to avoid excessive softening (causing extrusion) or hardening (causing cracking. Durometer Durometer or Hardness is measured in points with a Shore A instrument. Correlation of results is perhaps the hardest thing to assure when preparing a specification. they are discussed separately. Keep in mind the original tensile and elongation figures established in (b. add another variable to the tests since commercial fluids are not as tightly controlled as test fluids. This usually causes widespread confusion and enlarges the problem of correlation.). It is usually desirable to use the actual service fluid. freezing them.210 section O-rings and that the reverse is true with the butyl compound.19 Process Control The purpose of process control is to ensure uniformity of purchased parts from lot to lot. Expecting all size seals from a given compound to fall within a set volume swell limit at the most critical time period (70 hours) is unrealistic. normal production variation may cause the material to fall outside the limits. For instance. Determine the maximum amount of shrinkage that can be tolerated in the application (usually 3-4% for both dynamic and static). and finally recording the temperature at which the samples have returned to 9/10 of the original stretch (1/10 return). Volume Change 1. Parker believes that the Temperature Retraction Test (TR-10) is the best method for determining a compound’s ability to seal at low temperatures. Compression set varies with the elastomer. and the thickness of the test specimen. e. One should be careful not to be trapped by writing a specification based on one test report having only a single set of values. Furthermore. but very little about the temperature at which it is useful. four or eight weeks depending on the fluid and the elastomer) would give results much more indicative of the stabilized swelling characteristics of a material. Static O-rings normally function satisfactorily to about -8°C (15°F) below this.e. the type and amount of curing agents. This is not the case with TR-10 that consists of stretching 3 or 4 samples 50%. 2. and loss of elongation after immersion are indications of over aging.com . Remember that every designer should set limits for the control of all of these properties based on his past experience in the same or similar application. It sometimes requires longer to approach equilibrium value. 4. For these reasons.070 section nitrile O-rings swell much less than the . 1. Low Temperature Resistance Low temperature resistance is measured by determining the flexibility of an elastomer at a given low temperature. or laboratory samples. tolerances will apply as discussed in the Control Section on Elongation. A more realistic time (i. Figure 2-30 shows two graphs that depict these phenomena. Set the minimum and maximum limits necessary for control of the volume change of the compound in each fluid that will be encountered in the application. or a representative test fluid. 2. Functional tests indicate that O-rings will usually provide reliable dynamic sealing at or below the TR-10 value. other compounding ingredients in the compound.< Back Section Contents Parker O-Ring Handbook Table of Contents Search Next > c. but only if their inherent limitations are understood.070 inch will not have the same volume swell as will an O-ring of the same compound with a .

Process control may be based on the requirements of the qualification section or actual qualification test results. see “Physical and Chemical Characteristics” earlier in this section (paragraph 2. Normally neither the customer nor the manufacturer can afford such time for prolonged testing. Elongation Change Experience will dictate this limit as noted under tensile change. Both of these methods have inherent weaknesses. Once limits are set. f. Remember that shrinkage is a prime cause of failure. The low temperature test method that most nearly simulates the actual service requirement should be chosen to give the best possible assurance that the seal which passes this test will function in the application. the temperature of the test. this difference is at its peak during the first 70 hours (a popular standard test time) and most accelerated testing is specified within this time period. is very unlikely to reflect mean values Basic O-Ring Elastomers 2-31 Parker Hannifin Corporation • O-Ring Division 2360 Palumbo Drive. This could result in unnecessary rejection of good parts. A realistic value for compression set is all that is necessary to assure a good state of cure and resilience of a compound. For more information. Determine the maximum amount of swell that can be tolerated in the application (usually 15% to 20% for dynamic and 50% for static). notice that . Once again it is necessary to stress the difference between test results on different size seals. loss of tensile strength. When a material is qualified to a specification close to the specification limits. d. then warming them gradually at a constant rate. Compression Set Compression set is usually measured as the amount that a material fails to recover after compression. This temperature (TR-10) then is the lowest temperature at which the compound exhibits rubber-like properties and therefore relates to low temperature sealing capabilities. 2.parkerorings. Excessive softening.4). Excessive hardening. Any single set of tests made on a particular batch. qualification volume swell testing must be limited to definite test samples. This only tells at what low temperature the compound is most likely to be completely useless as a seal in a standard design. gain of tensile strength.. an O-ring with cross-section of . Besides the extreme variation among different cross-section O-rings in the first two weeks of testing. Therefore it is suggested that control be based on actual test results of the material in question. Most low temperature tests are designed to indicate the brittle point of a material. The lowest temperature at which the seal is expected to function should be determined. Short-term test results are quite useful. Take into consideration dry-out cycles that may be encountered in service and include a dry-out test after the immersion test to provide a control for dry-out shrinkage. 3. With Parker’s CBI program it is practical to refer to the batch from which any seal was made.. b. Tensile Strength. the control section would specify 68 ± 5. This tolerance was taken into consideration when establishing the tensile strength qualification limit of 1200 psi for dynamic seals (see qualification section. if the qualification section specified 70-durometer ±5 and the qualification value was a 68-durometer reading.0 (2000) -57% -46% Tensile Strength — Bar (psi) 103. successful compounds.

Lexington. Discussion will be limited to only those properties really pertinent to the control section of the specifications.parkerorings. Many of the typical tests for determining a compound’s physical and chemical properties that are specified in the qualification section are unnecessary to provide good control of an approved material. This practice is less likely to result in unnecessary rejection of usable parts. Seal manufacturers have accumulated years of test experience on popular. A tolerance of ±5 points is the standard allowance for experimental error caused by reading techniques and production variance from batch to batch of the same compound. 4 Bar (1020 psi). The result is different compounds available for the same service.com . any one of which would perform satisfactorily in almost all the applications.02 tolerance is applied. manufacturing costs will increase due to higher scrap rates. (1) a controlled test fluid is used or control of the commercial fluid eliminates its variance.

Each seal supplier has developed numerous nitrile compounds to meet various specifications. thus minimizing inaccuracy (for example: if the balance being used is accurate to . Basic O-Ring Elastomers 2-33 Parker Hannifin Corporation • O-Ring Division 2360 Palumbo Drive. Specific Gravity of a compound having been established during qualification. If the compounder is forced to develop a material that is extremely difficult to process. when setting a limit for elongation for qualification. Guard against specifying unrealistically high physical properties that may in reality be detrimental to a seal due to the greater percentage drop-off of these properties after short periods of exposure to fluids (see Figure 2-31). Specific gravity is the easiest and quickest control test available to the industry today. Only the more common physical and chemical property tests have been discussed. It can be done if. In many applications. The customer ultimately bears these costs.

In some instances. It may have degraded enough that it cannot safely be reinstalled. Note the operating temperature range of the chosen compound. Specific design and dimensional data applicable to static seals is provided in the Static O-Ring Sealing Section (IV). the design of the O-ring seal has generally already been accomplished. Normally. the selected material must also have the toughness and abrasion resistance so important in reciprocating and rotary seals. must also resist extrusion when exposed to the maximum anticipated system pressure and be capable of maintaining good physical properties through the full temperature range expected. Whenever possible this should be a compound rated “1” for all the fluids under consideration. Where a “2” rated compound must be used.1 Compatibility Compatibility between the O-ring and the fluid or fluids to be sealed must be the first consideration in the design process. price and stock availability may become determining factors. but many will not. The temperatures shown in Table 7-1 are general temperature ranges. or to obtain improved performance from the seal will also be found in this section. Current piece-price and in-stock availability can be obtained from your nearest Authorized Parker O-Ring Distributor. The following paragraphs discuss the more important design factors that generally apply to all O-ring seals. compounds of other hardnesses in the same polymer are available.parkerorings. The necessary data for gland dimensions are simply selected from the tables in the sections on Static and Dynamic O-Ring Sealing. Bear in mind that “Static only” compounds are not as tough and abrasion resistant as other materials. but it should. or if the seal can be replaced often. Lexington.1. When a compound rated “3” is selected. If the fluid will have an immediate adverse effect (chemical reaction resulting in surface destruction. If more than one fluid is involved. it is best to determine the O-ring compound first. there is little advantage to be gained by proceeding further with the design until this basic problem is resolved. Data and procedures enabling the designer to depart from the standard designs in order to meet peculiar requirements. it may be necessary to compromise on a seal material having the best overall resistance to all the fluids involved. Such comparison should disclose any weak points where modification may be desireable or required. Parker O-Ring Distributor or contact the Application Engineering Department of the Parker O-Ring Division at (859) 269-2351. but the presence of a particular fluid may modify the published limits. for some reason a compound of different shore hardness from the one suggested in the Fluid Compatibility Table is needed.

If compatibility cannot be determined from specific data in this section or the Fluid Compatibility Tables in Section VII. loss of strength. If. a “Static only” compound will probably be satisfactory. both the sequence of exposure and time of contact with the O-ring need be considered. and would normally wear more rapidly in a dynamic environment. do not expect to re-use it after disassembly. If a compound designated “Static only” is the only compound recommended for the fluids. If the anticipated seal motion is infrequent. The Fluid Compatibility Tables in Section VII suggest potential Parker Compounds for over two thousand different gases. When two or more compounds are suitable for a given application. fluids and solids. only appropriate testing can safely determine an acceptable O-ring seal material. The value of making a detailed comparison between previously satisfactory installations and a new one cannot be over-emphasized. be certain it is first thoroughly tested under the full range of anticipated operating conditions. thus simplifying the process and facilitating the design effort. and information on dynamic seals is contained in the Dynamic O-Ring Sealing Section (V). a “2” rating is usually acceptable. refer the problem to your Parker Field Engineer. or other marked change in physical properties) resulting in shortened seal life.

Exposed bearings however. tests have shown that they suffer damage by shearing of the chains after only 2000 to 3000 working hours. the anticipated useful life is reduced to approximately 336 hours.10 Temperature Extremes 3.9. new synthetic concentrates. The most important physical properties of HFA fluids depend on their water proportion and vary greatly from mineral oils. The tendency to leakage of these low-viscosity fluids has caused a search for additives that would increase the fluid’s viscosity. but can be better described as a highly stable colloidal suspension of high viscosity oil drops in water.2 Concentrates Containing Mineral Oils (Oil-in-Water-Solutions) Oil is not soluble in water. On the down side however.< Back Section Contents Parker O-Ring Handbook Table of Contents Search Next > 3.17. Under these conditions. The earliest developments in HFD fluids have disappeared from the market because they were extremely poisonous. Parker Hannifin Corporation • O-Ring Division 2360 Palumbo Drive. Oil based hydraulic systems are increasingly being replaced by HFA fluids. At 232°C (450°F). They are not prone to the micro-biological attack. etc. bringing about a wide variation in the fluid’s properties. Should the water evaporate however. Certain FKM compounds are not compatible with HFC fluids. Most elastomer compounds that are compatible with mineral oils also can be used in HFC fluids (NBR for example). the working life of a hydraulic system using HFA fluid is significantly shorter than of a system using conventional hydraulic oils. 3.17. Mineral oil concentrates can contain practically all types of chemical additives that have thus far been developed.17. leaving enough recovery to continue sealing for many additional hours at that temperature. emulsions take longer to filter. 3. Only by employing emulsifiers it is possible to bring about a stable oil-in-water-solution. HFC fluids are regarded as special refuse and should be handled accordingly. which are similar to oils. wear resistant additives which form a high-pressure resistant film with good lubricating properties. Lexington. The effect of the environment must be carefully assessed. compatibility with most seal materials is rather limited.4 Synthetic HFA Concentrates (Solutions) Recently a number of synthetic HFA concentrates have been developed which form a stable solution in water and are also suitable carriers of semi-soluble additives whose purpose is to protect metal components such as brass and copper. O-Ring Applications 3-17 While polyethylene glycols exhibit relatively high resistance to shear.3 Micro-Emulsions Recently. Such growth however. As described above. With these kinds of fluids there is a great risk of micro-bacteriological growth which can lead to problems. The concentrate contains both water and oil soluble. containing all required anti-corrosion additives. The concentrates are mostly based on naphthenic oils and can cause problems with certain O-ring compounds. Working temperature ranges from -25°C to 60°C (-14°F to 140°F).6 HFD Fluids This group of hydraulic fluids consists of pure synthetic. The two glycols behave differently. ethylene propylene is generally superior to fluorocarbon.9.1 High Temperature The fluorocarbons are the most useful for high temperature sealing applications. 3.9. both synthetic and natural. The fluid can be used at pressures in the range of 300 to 350 Bar (4350 to 5075 psi) and represents the most expensive hydraulic fluid on the market. however. these materials have a very steep viscosity/temperature relationship curve which makes the working range of temperature very narrow. can be brought under control without difficulty by adding a biocide to the mixture. 3. Such emulsions have been used as hydraulic press fluids for decades.10. Their place has been taken by pure phosphate esters.9. the fluorocarbons tend to harden and take a premature set.17. In spite of this. In general. These fluids can be filtered finely as required because they are in complete solution. The wear resistant properties and viscosity of HFC fluids is good and corrosion may be controlled by additives.9.17. mineral oil remains behind. This is neither a true solution nor an emulsion. Although much easier to handle. have been developed which form micro-emulsions when mixed by 5% with water. In the presence of hot water or steam. The working temperature ranges from 5°C to 55°C (42°F to 130°F). Concentrates currently available at this time are limited to 100 Bar (1450 psi) working pressure and are mostly used in automated production lines. 3. water-free fluid and does not suffer from most of the previously mentioned difficulties. and have a useful life of more than one year.parkerorings. which are essentially non-toxic. When the water evaporates. The temperature range is an improvement over mineral oil based fluids. Parker’s fluorocarbon compound V0747-75 took a 66% set. Disposal is problem-free but must still be classified as special refuse. still remain very susceptible to corrosion due to high water content and the working life of equipment is thereby shortened.5 HFC Fluids HFC hydraulic fluids consist of a solution of polyethylene and polypropylene glycols in a proportion of between 35% and 55%. In a 1000 hour air age test at 204°C (400°F). This is especially true with working pressures over 200 Bar (2900 psi). compound N0951-75 has the best high temperature properties. but this is true only when the test specimen is exposed to circulating air. 3-18 The Fluid Compatibility Tables can be used only as a guideline. silicone (S1224-70) and fluorosilicone (L1120-70) should be selected for low temperature applications.10. the answer may be a fluorosilicone. elevated temperatures are additionally dangerous. a static seal may have a minimum functional temperature of about 15°C (-8°F) lower than the TR-10 point. The actual lifetime of a seal at low temperature depends on the application and on the medium to be sealed. however. (5) In water/steam. (2) Special compound. 3.

In laboratory tests. as does a rapid rate of pressure drop. a variation of ±50% from the predicted value should be anticipated to allow for limitations in the accuracy of test equipment and available standards. It was set up this way because in the United States O-ring diameters are usually given in inches.4 . The permeability rate of a gas through an O-ring is proportional to the pressure differential across the seal. it was found that soaking compound N0304-75 in MIL-H-5606 oil for 24 hours at 135°C (275°F) prior to testing dramatically curtailed the severity of the damage.

In strong solutions, the acid resistant fluorocarbon compound often maintains its properties rather well, particularly at room temperature. In the Fluid Compatibility Table in Section VII, it is shown as the only compound that is likely to withstand the effects of concentrated nitric and hydrochloric acids at room temperature. At higher temperatures in these acids, only a perfluoroelastomer can be expected to maintain a seal on a long term basis. In dilute solutions, an ethylene propylene compound is usually preferred, particularly if there is any elevated temperature involved, because ethylene propylene has excellent resistance to water as well as quite good acid resistance. It is particularly important to test seal compounds under service conditions when a strong acid is to be sealed at elevated temperatures. 3.14.1 Plastic Contact Surfaces Sometimes when an O-ring is used in contact with a plastic material, the plastic will develop a series of fine cracks that weaken it. This “crazing” has been noticed most frequently with polycarbonate resins, such as General Electric’s Lexan, but it has also been found in other plastic materials. This effect is most severe when the plastic material is under the greatest stress, and may be caused by stress alone. For instance, compounds E0515-80, N0522-90 and V0709-90 were rated “marginal,” but we feel that the problem with these elastomers may have been caused by their hardness, as we would not expect a chemical effect between them and a polycarbonate resin. General Electric Company has tested a number of Parker Seal Compounds with Lexan and found that the following materials are generally acceptable in contact with Lexan. See Table 3-21. Compounds for Use Against Lexan(1) Surfaces Ethylene Propylene E0692-75 (marginal) E0515-80 (marginal) O-Ring Applications 3.14.2 Silicone Fluids Silicone fluids are chemically very stable. Reference to the Fluid Compatibility Table in Section VII, for instance, shows that all types of seal polymers except silicone rubber may be used for silicone oils and greases. There are some individual compound exceptions. Silicone fluids have a great tendency to remove plasticizer from compounds, causing them to shrink. The effect is most severe with the combination of low viscosity silicone fluids in high temperature environments. Because of this, military nitrile compounds, and any other nitriles with a low temperature limit below -40°C (-40°F) should not be used to seal silicone fluids as such low temperature nitriles must contain large amounts of plasticizers. Other compounds, including the high temperature nitriles, should be tested before use to be certain they will not shrink more than one or two percent. Silicone rubber is rated 3 (doubtful) in contact with silicone fluids. The poor rating is given because silicone rubber tends to absorb silicone fluids, resulting in swelling and softening of the rubber. Occasionally, however, it is desirable to seal a silicone fluid with a silicone rubber O-ring. This combination is generally acceptable if the viscosity of the silicone fluid is 100,000 centistokes or more, and if the maximum temperature will not exceed 149°C (300°F). 3.14.3 Underwriters’ Laboratories Common Parker compounds are listed by Underwriters’ Laboratories (UL) under their “Recognized Compound Program.” The listing is based on UL testing of compound for specific service requirements as shown in Table 3-22. 3.14.4 Water and Steam Resistance Water seems like such an innocuous fluid; people are often surprised to learn that it can bring problems if it is not sealed with the proper O-ring material. After a long period of water immersion, many compounds will swell quite drastically. In a static seal, this may be quite acceptable. Such a seal surely will not leak, and if it can be replaced with a new one after disassembly, the fact that it has become too large to put back into the gland cavity becomes only an interesting curiosity. In situations where the O-rings are routinely replaced before they have swelled more than a few percent, the user may not even be aware of their strange behavior. Used as a long-term dynamic seal, however, this gradual swelling of many compounds in water can cause a slow but very annoying increase in both breakout and running friction. Figure 3-12 and Figure 3-13 illustrate this gradual swelling of a number of Parker Seal compounds when exposed to water at two different temperatures. From these curves it will be seen that E0540-80 ethylene propylene rubber is the single compound tested that had virtually no swell. This is our recommended compound for water and steam for temperatures up to 149°C (300°F). Where exposure to steam and hot air alternate, as in tire presses, it serves better than in either one alone.

Not only to prevent system contamination from the external environment, but they must not contribute any contaminates to the system in their own right. Specific needs are required by each of the four primary environments employed by the semiconductor industry: • Gases & Vacuum • Thermal • Plasma • Wet Processing Working conditions: Temperatures: up to 300°C (572°F) Pressures: vacuum to 10-9 Contact our Application Engineering Department regarding Semiconductor sealing applications. 3.16 inPHorm Seal Design and Material Selection Software Parker recommends utilizing our inPHorm design software to guide the user through the design and selection of an O-ring and corresponding seal gland. Parker’s inPHorm not only addresses standard o-ring sizes, but will allow the user to custom design O-ring glands and seals specifically for their application. To obtain inPHorm software contact the O-Ring Division, Parker Product Information at 1-800-C-PARKER or download from www.parkerorings.com. If inPHorm is not readily available manual calculations can be performed. 3.17 Drive Belts 3.17.1 Introduction O-rings and lathe-cut rings are being used extensively as low power drive belts because they are inexpensive and simple to install. Due to their resilient nature, they do not require the use of belt tensioning devices, and pulley locations do not need to be extremely accurate. For most elastic drive belt applications, O-rings are preferred over lathe-cut rings for a number of reasons: (a) Ease of installation. (b) Uniform stress distribution. (c) Ready availability of many standard sizes. (d) Flexibility of usage. (e) No sharp corners on the belt. Lathe-cuts are often completely adequate for the task, but they are more likely to require special tooling, making the cost prohibitive when only a small quantity is needed. For large quantities, the tooling cost becomes insignificant, and overall cost savings are generally realized in using lathe-cut rings. Due to the special manufacturing techniques employed, all lathe-cut applications are reviewed by the O-Ring Division’s Application Engineering Department. Parker Seal is conducting a continuing program of testing compounds for drive belt service, and developing new drive belt compounds to optimize the properties that are most needed in a drive belt.

The choice of elastomer is determined by the physical environment: • Contact medium, ozone, oil, grease. • Service temperatures. The general requirements for elastomer drive belt materials are: • Good aging resistance. • Wear resistance. • Relatively low tendency to return to original shape under tension and temperature caused by friction; this means a higher resistance to the Joule effect. • Good flexibility. 3.17.3 Available Drive Belt Compounds The information below describes the most suitable drive belt compounds available. The Application Engineering Department should be contacted for additional information. E0751-65 has been developed specifically for drive belt use. Performance data from production samples show that it has properties superior to O-ring compounds recommended formerly, and E0751-65 has become the “standard’’ drive belt compound as a result. The most important of its properties are low stress relaxation combined with reliability and resistance to high temperature. A limitation that prevents its use in a few applications is its lack of resistance to petroleum fluids.

Table 3-23: Parker Seal Elastic Drive Belt Compound Data Some O-ring seal compounds have been used successfully in many drive belt applications. The three materials described below have been evaluated specifically for this type of use and gave superior performance under the conditions stated: P0642-70 has been a very successful material for drive belt applications. It is recommended for severe conditions where extra abrasion resistance, long life, and high stress values are required and service temperatures do not exceed 54°C (130°F). Its major attribute is reliability, which is due to the excellent flow characteristics of polyurethane that minimize the possibility of poor knitting. It is a particularly tough material, having high tensile strength and excellent resistance to abrasion, wear, and fatigue. C0873-70 is recommended where the service temperature exceeds 54°C (130°F) and there is a possibility of contact with petroleum fluids. It has outstanding resistance to stress relaxation at temperatures as high as 82°C (180°F), though its resistance to fatigue is not as good as other Parker drive belt compounds. S0604-70 is the compound generally selected for high temperature use or for applications where the black color of the other drive belt compounds is not permissible. Being a silicone, however, it does not have the tensile strength or resistance to wear and abrasion of the other compounds. The user, therefore, should not sacrifice these important properties by specifying an unrealistically high temperature to provide a “safety factor”. Usually some excess temperature can be tolerated if the exposure time is of short duration and is repeated only a few times during the life of the drive belt. It should be remembered that the physical properties of any compound will be poorer at elevated temperature. Table 3-23 compares the important properties of these rubber materials. Specific gravity and stress relaxation are listed first because these data are needed in drive belt design. When drive belts may contact fluids not listed in Table 3-23, refer to the Fluid Compatibility Tables in Section VII. In any case, contact of elastomeric drive belts with any liquid must be kept to an absolute minimum. Almost any liquid on the belt will reduce friction, causing slippage. Since contact with fluids is seldom encountered in drive belt practice, this becomes a minor consideration. 3.18 Applications Summary In the foregoing discussions on special applications, there are necessarily many references to problems and failures, but the object of pointing out possible pitfalls is to indicate to the designer the steps he can take to avoid them. The object of this whole reference manual, then, is the very positive one of showing how to produce reliable, economical, effective O-ring seals for a diversity of uses. An important factor in most O-ring seals is the rubber compound from which it is made. For the special applications presented in this chapter, many specific compound recommendations are included. Parker Compound recommendations based on fluid type alone will be found in the Fluid Compatibility Tables in Section VII. It is an excellent practice, after selecting one or more likely materials, to study those portions of the Elastomers section that apply to that material. Background information is given there that will give the designer a better understanding of the general properties of each of the major polymers, and help him select wisely when a choice or compromise must be made. The explanations of physical properties and how they are tested are also necessary for an adequate understanding of rubber materials and their behaviour in different operating environments.

No adjustment or human factor comes into play when O-rings are assembled originally or used in repairs if the gland has been designed and machined properly. O-rings do not require high bolting forces (torque) to seal perfectly. O-rings are versatile and save space and weight. They seal over an exceptionally wide range of pressures, temperatures and tolerances. Once seated, they continue to seal even though some feel that they theoretically should not. In addition, they are economical and easy to use. Therefore, we agree that the O-ring is “the finest static seal ever developed.” 4.1 Surface Finish for Static O-Ring Seals The design charts indicate a surface roughness value not to exceed 32 micro-inches (32 rms) on the sealing surfaces for static seals with a maximum of 16 rms recommended for face-type gas seals. These figures are good general guidelines, but they do not tell the whole story. Equally important is the method used to produce the finish. If the surface is produced by turning the part on a lathe, or by some other method that produces scratches and ridges that follow the direction of the groove, a very rough surface will still seal effectively. Some methods such as end milling or routing, however, will produce scratches that cut across the O-ring. Even these may have a rather high roughness value if the profile across them shows rounded “valleys” that the rubber can readily flow into. Usually, these tool marks have sharp, deep, angular valleys that the O-ring material will not penetrate or fill completely. For this type of surface, the recommended roughness values should not be exceeded. 4.2 Static Male and Female O-Ring Seal Design Design Chart 4-2 and its accompanying Design Table 4-2 give one set of dimensions for static O-ring seals when the configuration is similar to a piston or rod application with no motion involved. Aerospace Design Standard AS5857 is shown in Design Chart 4-1 and Design Table 4-1 for aerospace and military applications. For applications requiring more than two or three percent stretch on the inside diameter of the O-rings, refer to Figure 3-3 to determine the effective “W” dimension for the stretched ring. The desired percent squeeze should be applied to this cross section diameter. In large male gland assemblies, it may be desirable to use an O-ring one size smaller than indicated in the design chart. The design stretch is so small in these large sizes, that the O-ring tends to sag out of the groove before it is assembled. Using the next smaller size simplifies assembly, but requires a reduced gland depth to attain the proper squeeze. The need for back-up rings should be investigated for pressures exceeding 103.5 Bar (1500 psi) (for all seal types). If there is no extrusion gap, back-up rings are not required. Very high pressures can be sealed without back-up rings if metal-to-metal contact (practically zero clearance) of the gland parts can be maintained. Instances have been reported of sealing pressures of 13,600 Bar (200,000 psi) with a 70 Shore A durometer Oring without back-up rings. Vibration or pressure fluctuation sometimes will produce “breathing” which requires back-up rings at average pressures below 103.5 Bar (1500 psi). When using silicone O-rings, the clearances given in the design charts and tables should be reduced 50%. For examples of static seals, see Figure 4-1 (female gland) and Figure 4-2 (male gland). O-ring Pressure Use the system pressure to close clearance gap. Added wall support on plug seal minimizes breathing. External threads prevent O-ring damage during assembly. Figure 4-1: End Cap Seal Figure 4-2: Plug Seal 4.3 Face Type Seals Design Chart 4-3 explains how to design an O-ring seal when the groove is cut into a flat surface. Note that when the pressure is outward, the groove outside diameter (OD) is primary, and the groove width then determines the inside diameter. Conversely, when the pressure is inward, the groove inside diameter is primary. This design technique minimizes movement of the O-ring in the groove due to pressure, thereby virtually eliminating wear and pumping leakage. If this principle is used, groove diameters larger or smaller than indicated may be used. Two possible groove widths are shown in this chart, one for liquids, and the other for vacuum and gases, the extra width for liquids allows for some minimal volume swell. In vacuum applications, the narrower width allows for faster pump down and reduces dead volume in which gas can be trapped. In sealing a liquid that is known to cause no swelling of the O-ring elastomer, the narrower groove would be suitable. Design Chart 4-3 is preferred over Design Chart 4-2 for static face seals because it calls for a heavier squeeze in all but the smallest (.070) cross-section rings, thus improving reliability at low temperatures. In a male or female gland design, the amount of squeeze required by Design Chart 4-3 is quite difficult to assemble. 4-2 Parker Hannifin Corporation • O-Ring Division 2360 Palumbo Drive, Lexington, KY 40509 Phone: (859) 269-2351 • Fax: (859) 335-5128 www.parkerorings.com < Back Section Contents Parker O-Ring Handbook Table of Contents Search Next > The 4-3 and 4-7 design charts are often used for vacuum seals. See O-Ring Applications, Section III, for assistance in finding the best rubber material and calculating the approximate leak rate for a face type static seal used for a vacuum or a gas. Face type seals are sometimes rectangular. In designing such a seal to receive a standard O-ring, the inside corner radii of the groove should be at least three times (ideally six times) the cross-section diameter of the O-ring to avoid over-stressing the ring or causing corner creases that would potentially leak. 4.4 Dovetail and Half-Dovetail Grooves It is sometimes necessary to mount an O-ring in a face type groove in such a way that it cannot fall out. The dovetail groove described in Design Charts 4-4 and 4-5 will serve this function. This groove is difficult and expensive to machine, and the tolerances are especially critical. It should be used only when it is absolutely necessary. 4.5 Boss Seals The AS568-901 through -932 O-ring sizes (Parker’s 3- series) are intended to be used for sealing straight thread tube fittings in a boss. Design Table 4-3 and Design Table 4-4 show the two standard boss designs that are used for this purpose. Both of these bosses use the same O-ring, but Parker Seal Group recommends the Design Table 4-4 design when there is a choice. It is the newer design, and it has not been fully accepted yet by industry or by the military though there is a military standard for it. The 4-4 dimensions provide for closer tolerance control of the O-ring cavity and distort the O-ring less when assembled. The improved tolerance condition assures much less trouble due to leakage resulting from insufficient squeeze or extrusion when the older cavity is too small. The reduced distortion gives a longer life. 4.6 Failures and Leakage By far the most common type of failure in static O-ring seals is extrusion. This is relatively easy to prevent if the curves of Figure 3-2 are used when the seal assembly (groove and seal element) is designed. “Pulsing” or “pumping” leakage occasionally occurs when system pressure alone causes the O-ring to rotate in the groove and the resilience of the seal returns it to its original position. To avoid pumping leakage, design the gland so that the normal position of the seal cross-section will be on the low-pressure side of the gland or use a narrower groove. Porous castings, eccentric grooves, out-of-tolerance parts, tool marks, and distorted or breathing glands are also frequent contributors to static O-ring seal malfunctioning and failure. Cast housings and parts fabricated from powdered metal are commonly vacuum impregnated with an epoxy to seal minute pores. In this impregnation process, it is standard procedure to wash excess epoxy from the surface with acetone before the parts are given an oven cure. This washing process may be overdone to the point where small fissures on the surface are re-opened causing leakage under the seal in spite of the epoxy impregnant. It is advisable, after the acetone bath, to paint the sealing surface with a thin film of epoxy and wipe off the excess before oven curing. Leakage due to breathing, distortion, and incorrect machining requires a careful analysis of the problem and a consideration of the possible alternatives to find the most economical solution. When one of these causes is suspected, however, the possibility of porous metal should also be considered. For additional information on O-ring failures, see Section VIII, Failure Analysis, in this handbook. 4.7 O-Ring Glands 4.7.1 O-Ring Glands (Per SAE AS5857) for Aerospace Hydraulic (Static and Reciprocating) Packings and Gaskets The SAE Aerospace Standard (AS) 5857 provides standardized gland (groove) design criteria and dimensions for elastomeric seal glands for static applications. The glands have been specifically designed for applications using SAE AS568 size O-rings at pressures exceeding 1500 psi (10.3 MPa) utilizing one or two anti-extrusion (backup) rings and applications at pressures under 1500 psi (10.3 MPa) without backup rings. The glands have been sized to provide increased squeeze as compared to AS4716 (shown in Section V) for more effective sealing at low temperatures and low seal swell conditions. These glands are not recommended for dynamic use. Primary usage is for static external sealing. The rod dimensions are the same as AS4716. The cylinder bore dimensions are the same as AS4716 except for sizes -001 through -011 and -104 through -113. For additional information on SAE AS4716, see Section V, O-Ring Glands (Per AS4716) For Aerospace Hydraulic (Reciprocating) Packings And Gaskets. 4.7.2 O-Ring Glands for Industrial Static Seals Design Chart 4-2 provides the basis for calculating gland dimensions. For standard O-ring sizes, these dimensions have been calculated and are listed in Design Table 4-2. The procedures for the use of Design Table 4-2 are outlined in the guide below. After selecting gland dimensions, read horizontally to determine proper O-ring size number. Refer to Basic O-ring Elastomers and O-Ring Applications, Sections II and III respectively, for help in the selection of the proper compound. Remember, the effective part number for an O-ring consists of both a size number and a compound number. Refer to Appendix, Section X for installation information.

Section Contents Table of Contents Search Next > Parker O-Ring Handbook Dynamic O-Ring Sealing Dynamic O-Ring Sealing 5.1 Introduction Dynamic O-ring sealing applications are considerably more involved than static applications due to the implied motion against the O-ring seal interface. Resistance to fluids must be more carefully scrutinized than in conventional static seal designs since a volumetric increase in the O-ring in excess of approximately 20% may lead to friction and wear difficulties, and only a minimum of shrinkage (at most 4%), can be tolerated. The metal or other surface over which the O-ring will move also becomes critical. It must be hard and wear resistant. It also must be sufficiently smooth so that it will not abrade the rubber, and yet there must be small microfine “pockets” on the moving surfaces to hold lubricant. The greatest dynamic use of O-rings is in reciprocating hydraulic rod and piston seals. These are discussed first, but many of the ideas expressed are also applicable to other dynamic applications. Considerations applying only to other types of dynamic seals are discussed in greater detail later in the section. 5.2 Hydraulic Reciprocating O-ring Seals O-rings are best when used on short-stroke, relatively smalldiameter applications. Millions of O-rings however, are used very successfully in reciprocating hydraulic, pneumatic, and other fluid systems which employ long stroke, large diameter seals. If designed properly, an O-ring seal will give long, trouble-free service. The following discussion is presented so that common troubles and misuses can be avoided. If the engineer or designer is to become his own seal expert, he must learn the basic types and causes of seal failure. In this section we present a discussion of failures and causes of various seal failure modes even though it may overemphasize the problems. Reciprocating seals are affected by extrusion, breathing, surface finish of the metal, and hardness of the seal as discussed in O-Ring Applications, Section III. These factors should therefore be considered in any reciprocating gland design. There are also additional factors discussed in this chapter that must be considered in order to avoid future difficulty. Materials for the surface(s) over which moving O-rings slide should be chosen carefully. Those that give the maximum life to moving O-ring seals are: Cast iron or steel for bores, hardened steel for rods, or hard chrome plated surfaces. Soft metals such as aluminum, brass, bronze, monel and some stainless steels should be avoided in most dynamic applications, although they may be used in low-pressure pneumatics. If the cylinder bore surface can be hardened, as by carburizing, cylinder life will be increased. Hardness of the piston should always be lower than the cylinder walls to minimize the possibility of damage to the cylinder bore surface. Preferably, metallic moving surfaces sealed by an O-ring should never touch, but if they must, then the one containing the O-ring groove should be a soft bearing material. It is impossible to run a highly polished piston rod through a hard bearing without inflicting scratches on the rod. It is likewise impossible to slide a hard piston in a highly polished cylinder and not inflict scratches on the cylinder wall. The scratches are usually caused by small hard particles that are loosened and picked up by the oil which sooner or later become jammed between the moving surfaces and score them. Though they may be hairlines, they are longitudinal scratches and will therefore reduce sealing efficiency and life of the O-ring. The most satisfactory bearing material tried for this purpose is babbitt metal. Babbitt makes an excellent bearing and the hard particles become imbedded and captured in it without damage to the hardened rod. In fact after millions of cycles, the babbitt imparts a glass-like finish to the rod. Nylon may also be used as a bearing material, but the bearing may need to be split in some fashion to allow for nylon’s relatively high coefficient of thermal expansion. In a suggested design, Figure 5-1, the piston is surfaced with babbitt. The gland is also lined with babbitt. The O-ring may be located in the babbitt lining or in the supporting metal which should be relieved 0.051 or 0.076 mm (0.002 or 0.003 inches) so there will be no chance of the hard metals running together. Lubrication, as explained in O-Ring Application, Section III, is useful in all O-ring seals. It is doubly important in dynamic applications where a lubricating film between the O-ring, and the surface it slides over, will protect the ring from abrasion, frictional heating and rapid wear. In pneumatic applications, a back-up ring will trap some lubricant, and extend the useful life of seals that are lubricated infrequently. It will also help retain oil in applications powered with lubricated air.

Equipment exposed to such conditions should be fitted with a wiper/scraper ring to prevent the dirt from reaching the O-ring seal. It is also good practice to install a felt ring between the scraper and the seal to insure proper lubrication of the rod on its return stroke. Figure 5-2 illustrates this concept. A felt ring may cause corrosion in some installations, as felt also tends to collect moisture. A second O-ring may be used for the wiper, but it must not actually seal because a pressure trap condition is likely to develop between two reciprocating Enlarged View of Felt Wiper Gland with Felt Installed in Groove in Squeeze Condition O-ring seals. This can be prevented by cutting the outer O-ring so it cannot seal. Since this can easily be forgotten, it is preferable to provide a vent hole between the two O-rings. It should vent downward so it will not become clogged with dirt. The sample problem provided in Table 5-1 explains how to design the gland for such an O-ring wiper. 5.3 Surface Finishes Finishes of contact surfaces have much to do with the life of dynamic O-ring seals. Limits of maximum roughness for glands are given on the drawings accompanying the design charts in this section and represent accepted practice for military and industrial use. Surface roughness values less than 5 micro-inches are not recommended for dynamic seals, however, as an extending rod will be wiped completely dry and will not be lubricated when it retracts. The surface must be rough enough to hold small amounts of oil. Ideally, a microscopic “orange peel” type of surface is best, presenting smooth rounded surfaces for the O-ring to slide on, with small crevices between to act as oil reservoirs. This kind of surface may be approximated by peening the rod with metal shot or glass beads. An even better surface can be obtained by electropolishing. The most desirable surface roughness value is from 10 to 20 micro-inches. The roughness of a surface as measured comprises several elements which can be handled separately according to DIN 4760: Level 1 — dimensional deviations within tolerance band Level 2 — surface undulations (waves) Levels 3 to 5 — range of roughness All these deviations from the ideal finish are superimposed as measurements are carried out and represent the surface roughness (see Figure 5-3). Surface finish is often quantified in terms of Rt and Ra (see Figure 5-4). Rt is the vertical distance between the highest and the lowest peaks in a roughness profile over a test length lm. Rt is increasingly being replaced by the maximum depth of roughness, Rmax. Rmax is the greatest single roughness found in five consecutive single trace lengths lm. Dynamic O-Ring Sealing 1/8 Ref.

In this case Z4 = Rmax does not include extreme roughness peaks as is the case of Rt. The medium roughness value Ra is an arithmetic mean of all components of the roughness trace within the trace length lm. The average roughness value Rz of five consecutive trace lengths often is preferred to Re. If Ra is known, Rz can be taken from Figure 5-5 and vice versa. Figure 5-5 is taken from DIN 4768, part 1, attachment 1. Should Rz reach the upper portion of the graph, it can be assumed that the specified Ra values will not be exceeded. The lower limits would be taken if an Rz value should be specified. Finally, the depth of roughness Rp also is of interest and is the vertical distance between the highest point on the roughness trace and the center line of that trace. Values for Rt are of very little assistance in reaching a conclusion regarding the suitability of a surface roughness from the sealing point of view. Table 5-1 shows that for a similar Rt all levels of roughness can be produced. Ra values are unsuitable for comparison because profiles 6 and 7 have the same Ra value. Rp values without reference to the load area tp also gives a false impression of roughness. A static sealing surface Rt ≤ 6.3 µm (VVV roughness DIN 3141) is rougher than the dynamic surface requirements. Seal manufacturers recommend a roughness Rt ≤ 2.5 µm for a dynamic sealing surface (Ra = 0.25 to 0.5 mm) (VVV roughness DIN 3141) when the load area is over 50%, or when the surface finish roughness Rp is under 50%. These limitations often are overlooked, nevertheless the connection between surface finish and load area is very important because an “open” profile can have sharp edges (e.g., profiles 2 through 6 in Table 5-2). These open profiles are a product of cutting processes such as turning or grinding. A much larger load area is produced by cold forming processes such as rolling, drawing or sinking. e lm = 5 x le Rz = 1 (Z1 + Z2 + Z3 + Z4 + Z5) 5 Rp = Depth of Roughness Ra = Middle Roughness Value Ra Rp lm Figure 5-4: Roughness Terminology Relationship Between Ra and Rz 2000 1000 500 250 125 63 50.000 31.500 20.000 12.500 8.000 5.000 3.150 Ra Upper limit for Rz when transposing from Ra to Rz Deviation Ra Value in μ m 2.000 1.250 0.800 0.500 0.315 0.200 0.125 0.080 Ra Ra-Value in μ inch 32 16 8 4 2 1 Upper limit for Ra when transposing from Rz to Ra 0.050 0.032 0.020 Rz Rz 0.16 0.40 1.0 2.5 6.3 16 40 100 250 10 25 63 160 1.6 4.0 0.25 0.63 Rz Value in μ m Figure 5-5: Relationship Between Ra and Rz 5-4 Parker Hannifin Corporation • O-Ring Division 2360 Palumbo Drive, Lexington, KY 40509 Phone: (859) 269-2351 • Fax: (859) 335-5128 www.parkerorings.com < Back Section Contents Parker O-Ring Handbook Table of Contents Search Next > It can be clearly seen from Figure 5-6 that surfaces produced by roller burnishing have no sharp peaks which can cause damage to a seal. Further, the valleys form potential lubrication reservoirs which improve the dynamic behavior of a seal. Surface finish values obtained in a single test are possibly not typical. For this reason several readings should be taken. When several results are to be compared, the length of the test surface must be stated — for different trace lengths, results are not comparable because they result from other profile heights. 5.4 Temperature Effects On Dynamic Seals High Temperatures — It should be remembered that the higher the temperature (above 38°C) (100°F) in and around a reciprocating gland, the more critical the application becomes. The higher the interface temperature, the greater the tendency of the lighter fractions of the oil to evaporate from an exposed surface. Lack of lubrication will cause greatly accelerated seal wear. If the temperature is high enough, the tacky residue (resins) which remains after oil evaporation will char and create a hard, abrasive surface which, if not removed, will quickly abrade away the seal until leakage or complete seal failure occurs. Low temperatures — Low temperature environments are most troublesome, especially if the seal has been operating at a high temperature for some time. This is because the elastomer in the seal will take a compression set at high temperature. When the seal is then subjected to low temperature, there may be insufficient elastic memory to overcome the relatively high coefficient of shrinkage (10 times that of steel) at low temperatures. Rt Rp 1. Rt Rp 2. Rt Rp 3. Rt Rp 4. Rt Rp 5. Rt Rp 6. Rt Rp 7. Rt Rp 8. Rt Once unseated from a spot on a given metal surface, the seal must be reseated by internal seal resilience or system pressure. Therefore, it is much easier to seal a hydraulic system that goes from zero-pressure to high-pressure almost instantaneously. Low-pressure fuel, pneumatic, oil, and similar fluid systems are prone to leak if an O-ring is used as a dynamic seal at -54°C (-65°F) because there is insufficient pressure to keep the O-ring tightly seated during and immediately after motion of the gland. Remember that the -54°C (-65°F) compound is flexible and capable of acceptable seal performance at -54°C (-65°F) but may not be resilient below -43°C (-45°F). 5.5 Side Loads Side loads on a piston or rod can cause the clearance in the gland to be on one side only. If excess clearance is created by side-loading, extrusion will result. If adequate squeeze has not been applied, leakage will result. The higher unit load on the opposite side causes uneven friction on the seal, and if high enough, the rod or barrel will be galled or scored. 5.6 Direction of Pressure The placement of a groove can be determined from the direction of the system pressure in relation to the direction of the moving friction force. If the friction of the moving metal surface across the O-ring is in the same direction as the direction of pressure, the O-ring will tend to be dragged into the gap more readily and thus extrude at only 30 to 40% of the pressure normally necessary to cause extrusion. By placing the groove in the opposite metal part, any friction will work against pressure. Snubbing cylinders, in which the motion and force create the pressure, are the usual culprits. 5.7 Shock Loads and Pressures Shock pressures, such as those created by the sudden stopping of a rapidly descending hydraulic hoist cylinder on which there is a heavy load, are often far in excess of the pressure for which the seal and the system were designed.

The reduction of friction with increasing velocity stems from the hydrodynamic properties of the lubricating fluid.3. Specific seal pressure is in general related to. • Axial loads and wear bands on pistons. 1 min. pure hydrodynamic friction which does not allow direct contact between the seal and the running surfaces is rarely reached. Friction caused by Orings increases with increasing pressure. Lexington. In absolute terms there are very large discrepancies according to the thickness of the lubricating film.. • Velocity of movement. the more lubrication is squeezed from between the seal and the running surface resulting in a non-lubricated vacuum. Stribeck diagram Normally the decision must be made between lower friction and high leakage. V μ min. Friction is proportional to the working pressure and therefore it is necessary to keep seal friction low. Friction is directly influenced by the seal diameter because the wear-area is greater. As complete lubrication (= flooding) occurs. reduction of the sealing force also results in an increased tendency to leakage. deformation. a wiper seal scrapes a shaft dry. Level of Starting Friction Dependant Upon Time and Compound 1.08 according to the proportion of lubrication/non-lubricated areas (Figure 5-11).8 b) 0. the more the contact surface consists of metallic “islands” and therefore again mixed friction occurs. However. The longer the down-time. 1 hr. As in many other areas break-out friction of elastomers is significantly higher than running friction. Unfortunately. Hardness and deformation of the seal influence the seal pressure. • Type of material and surface finish of surfaces. Initially the seal is in direct contact with the sealing face with few lubricated fields. Lip seals are more sensitive to pressure.< Back Section Contents Table of Contents Search Next > Parker O-Ring Handbook Dynamic O-Ring Sealing Related to the working conditions: • Working pressure. This is also true for harder compounds.4 10 sec. This relationship can be modified within certain limits by selection of the seal geometry.

Swelling means increase sealing force and increased friction. The dynamic piston actually causes less friction with increasing velocity. The result depends on the geometry of the seal. Leakage at a wiper seal will not occur until the seal wears. an unstable seal geometry due to swelling in the medium plays a role. In this condition the level of starting friction approaches that for dry friction and is up to 10 times that found in running friction (Figures 5-12 and 5-11). the seal geometry once again plays a role when. These factors cannot be quantified because they overlap and act cumulatively. At low pressures the friction varies to the piston speed.2 a) Break-out friction Coefficient of Friction μ Mixed friction Hydro-dynamic friction Coefficient of Friction 0. for example. Then follows a wider area of mixed friction where the coefficient of friction can drop as low as 0. tendency to adhesion.

Finally. • Working tolerances. This shows that the geometry of a seal directly affects the amount of friction. but not strictly proportional. the down-time and the surface finish play a role in increasing break-out friction. The optimum condition is a relatively thin lubricating film with sufficient adhesive properties. loss of fluid from a system increases. 1 day 1 wk.06 to 0. especially at low pressures. On the other hand lubrication can cause leakage amounting to the thick lubricating film with every stroke. Friction depends on a compound's sliding properties. The greater the metal surface roughness. The working pressure controls the width of clearance gaps and thereby the thickness of the lubricating film. At the beginning of a stroke the seal goes through three friction phases. µ = 0. to the system pressure. 1 mo. Apart from compound type and seal geometry. When the medium is mineral oil it would seem that sufficient lubrication is assured. Additionally. e.parkerorings.com . as found when lubricated air is not available.14. lubricating film and surface finish. the increase in friction causes high wear.2 Pneumatic Seals In principle the same conditions apply here as for the hydraulic seal. the mass is decelerated by the increasing friction in direction µH. Certain improvements can be made making the system stiffer. Breakdown of the lubricating film after long operation also results in contact between the seal and the metal surfaces. • The power is transmitted through the elastic body of the “compressible” oil. The potential energy stored in the spring accelerates the mass even further. Radial oscillation of the piston will occur when the lubricating film breaks down. except that the effects of certain extreme conditions are more serious. The stick-slip effect also is related to the friction at the sealing face. The most important factors can be seen in Figure 5-13. the break-out friction µH must be overcome by F1.

To accelerate a mass m from zero to maximum velocity. it can eventually be removed by a seal lip. With an O-ring seal the loss of grease can lead to total breakdown of the hydrodynamic lubricating film after only a few slow strokes. Break-out friction occurs when the three following conditions are present: • When the break-out friction is higher than the running friction a running velocity Vµ min (see Figure 5-11). Of all these factors. Figure 5-13 is valid only for a specific seal in a particular application. Conversely oils with strong film building properties do not break down under the same working conditions using the same seals. This makes the seal move in the mixed friction range. or better expressed the difference between break-out and running friction. The spring element is loaded with F1 and with increasing velocity the friction value µH reduces to µG and the force to F2. • The running velocity is Vµ min. Running velocity is a product of seal friction. 5. this means the smallest possible oil volume under pressure on the hydraulic side. plays an important role in evaluation and selection of a suitable elastomer. The effectiveness of lubrication with grease depends on the thickness of the original film and the running velocity of the seal (Figure 5-15). For other seals and applications the interdependence varies. Lubricated air gives more or less the same results as in a hydraulic application.

The friction. Here friction is shown as a function of pressure and velocity. Lexington. The lower the velocity the thinner will become the lubricating film. In the other extreme a lack of lubricating film causes problems due to high friction. stability is difficult to achieve because the relevant parameters often work conversely. To estimate friction. Stickslip is effected directly and negatively by long seal lips and sharp seal edges. in dynamic applications particularly these wear conditions can cause the seal to fail through abrasion. A rough metal surface normally is the cause of elastomer abrasion. Figure 5-15: Change in Original Film Thickness as a Function of Running Speed During a Single Stroke (Border Line Δ Theoretical maximum Values) This action has little effect upon the starting friction but brings a noticeable improvement in running friction levels. Wear in fluid solutions can be divided into four groups: • Scuff wear develops with metal-to-metal contact in the semidry condition where both materials tend to form mixed crystals. • Abrasive wear can affect both metallic and seal areas.4 Interdependence of Friction Wear and an Effective Seal In order to obtain a problem-free seal it is necessary to have stability with regard to the clearance gap to avoid possible extrusion. It is therefore quite understandable that seal manufacturers cannot give customers fixed figures regarding friction and wear for an individual seal. 5. These additives have no influence in rubber/steel or rubber/metal combinations. However. Metals are abraded by hard compounds or by hard foreign matter in the medium. Today’s high precision machinery tends in most cases to eliminate hydrodynamic lubrication because of the increased wipe-off effect.2 m/s. A soft compound favors a thicker film.4 m/s. velocity.

Often many of these factors are difficult to measure or reproduce. Information about seal lifetimes only can be made when all parameters affecting the seal are known and reproducible. • Fatigue wear becomes evident when particles are released from the metal structure and is usually the result of pulsating loads. Lexington. The lubricating film is very important but only one of the factors affecting seal friction. Other factors are. the risk of high stick-slip increases. for example. Hardness. Hard and soft compounds behave differently at high velocities.parkerorings. The instantaneous viscosity of the fluid also plays an important role in resisting the wiping effect of the seal. together with the width and length of a clearance gap is very important. If slow pneumatic piston velocities are achieved by throttling the pressurizing air. pressure. It is still not known which factors influence the lubricating film and which mechanisms act in the clearance gap. This means the seal always functions in semidry condition and for this reason wear resistance depends on: • properties of the compound.14. v = 1.0 m/s. However. • running surface roughness.14.

An extremely rough or fine polished metallic running surface both cause equally higher stick-slip. To keep friction as low as possible the lubricating film should be fairly substantial. The hardness determines the elasticity of the seal and assures that the seal gives way to the lubricating film under pressure. The first consideration is the lubricating film in the clearance gap. and changes in direction.

The ballooning effect that can occur at very low pressure usually pops the O-ring out of the groove the same as blow-out. The seal is satisfactory as long as the valve is not opened at or near the pressure necessary to cause blow-out.29 Seat Seals A properly designed check or poppet type valve. the space between the two faces becomes increasingly larger. use Design Table 5-4 for O-ring sizes and gland dimensions. Either of these should only be used when absolutely necessary to obtain the desired seal. etc. 5. Many designers and engineers make the costly mistake of trying to use a conventional groove (square or rectangular) design to hold the O-ring. forcing it out of the groove into some other part of the valve or system.

In addition to its good chemical resistance. Use groove widths given in the Static O-Ring Sealing and Dynamic O-Ring Sealing Sections. it must be remembered that cylinders tend to expand when pressurized.com . PTFE back-up rings may be used with most elastomeric O-ring seals. Lubrication is enhanced by rubber which absorbs system fluid and does not plate out on rubbing surfaces. At assembly. PTFE may be used over a wide temperature range. 3. Special sizes are also made to order. Wherever possible use two back-up rings. It is cheap insurance to use two Parbaks even in single acting installations. Acids and inorganic salts have very little effect on PTFE resin. they have been in use for a number of years. but reversal does no harm. a Parbak is required on both sides of the O-ring. and they cannot fall out of the O-ring groove. are generally usable through a temperature range of -40°C to 121°C (-40° to 250°F). Parbaks are contoured on one face to minimize distortion of the O-ring when under pressure. For installation. Parker’s Parbaks will not “collapse” or cold flow if used with proper groove designs. Thus.1 Introduction Parker’s Parbak® back-up rings help prevent extrusion in high pressure service and compensate for loose fitting parts. The standard sizes are listed in Table 6-1. Tolerances on these can be opened up until they permit these larger clearances to occur. and the extra Parbak does no harm. 6. Parbak rings are continuous.

If only one back-up ring is used. Lexington. The clearance that the Parbak will see is the clearance between the piston and the expanded cylinder.4. PTFE can also impair seal lubrication by plating rubbing surfaces with PTFE resin to which lubricating oil will not adhere.2 Anti-Extrusion Device Design Hints 1. the O-ring should be placed between it and the source of pressure. 5. The use of loose fitting parts makes for cost reduction in the machining of unit components. Parbaks are quick and easy to assemble. minimizing assembly costs.4 Other Back-Up Ring Materials 6. Continuous construction prevents damage to the O-ring seal. 6. Parbak® is a registered trademark of Parker Hannifin Corporation. it is too easy to place a single Parbak on the wrong side of the O-ring. PTFE back-up rings are supplied either scarf or spiral cut as shown in Figure 6-1. 3. yet the orientation of the contoured face is immaterial to the proper function of the part because it is flexible. Elastic memory permits Parbak rings to be stretched into place for assembly without preconditioning or cutting. preserving the O-ring and reducing friction. they do not have a cut because they can be stretched over the end of a piston during assembly. 6. 2. Parbaks should be installed with the contoured face against the O-ring. When tolerances are increased. By specifying one on each side of the O-ring. Parbaks in Parker Seal Group’s standard nitrile compound. Hence they contact the mating O-ring uniformly. The extrusion curves can be used in two different ways to reap the benefits of Parbaks. In high pressure applications. Refer to the appropriate Design Chart for recommended groove width. N1444-90. depending on the application. there will be one on the low pressure side. Features of Parbak Rings 1. 6-2 Parker Hannifin Corporation • O-Ring Division 2360 Palumbo Drive. These are special devices designed to satisfy a specific problem. Parbak rings help trap lubricant. These discontinuities may contribute to seal damage due to biting and pinching. In low pressure seals. one on each side of the O-ring. however. Unlike many PTFE back-up rings. Although no industrial or military standards have been issued for rubber back-up rings. Hardening of this material due to high or low temperatures often improves performance as a back-up ring. the curves will indicate wider permissible clearances than those given in the design charts. In using these curves. The 90 durometer curve in Figure 3-5 may be used to find the maximum recommended clearance at a given pressure for temperatures up to 74°C (165°F) when standard Parbak rings in Parker’s N1444-90 nitrile compound are used to protect an O-ring from extrusion.3 Parbak Elastomer Back-Up Rings Hard rubber back-up rings combine most of the best features of both leather and PTFE anti-extrusion devices.< Back Section Contents Table of Contents Search Next > Parker O-Ring Handbook Back-Up Rings p g Back-Up Rings 6. resulting in substantial machining economies. where it is needed. one must check to be sure that squeeze values do not become too high or too low.1 Polytetrafluoroethylene (PTFE) Back-Up Rings Anti-extrusion rings made from tetrafluoroethylene are impervious to oils and solvents.parkerorings.

Because an O-ring may wipe all lubrication from such a surface. 6. Functional tests have proven that millions of cycles can be obtained with Parbaks. They do not leave a deposit on the metal surface. reverse stroking is dry and greatly reduces seal life. If there is any question concerning the suitability of leather for the application. Leather back-up rings are manufactured as continuous rings and in most cases must be stretched during installation.

Leather back-up rings should never be cut to facilitate installation.2 Metal Non-Extrusion Rings In most cases it will be impracticable and unnecessary (under 1380 bar 20. Parker Seal has developed other compounds for installations requiring special characteristics.parkerorings. The standard compound for Parbaks is N1444-90. In addition to N1444-90. It is resistant to nearly all hydraulic fluids except certain non-flammable types such as Skydrol. Careful engineering and research has produced N1444-90 which has the best combination of characteristics for the majority of back-up ring installations — broad temperature range.3 Leather Back-Up Rings Leather was a standard back-up ring material for many years. showing their tremendous superiority over the older types of back-up rings.e. toward or away from the O-ring.

(See Section II.) Identification of Compression Set Failure A typical example of classic O-ring compression set in simplistic terms: the O-ring ceases to be “O” shaped and is permanently deformed into a flat sided oval. O-ring seals are susceptible to failure.

Parker suggests the engineer obtain a copy of Publication AIR1707. 10.) There are a number of factors that can contribute to compression set failure of an O-ring seal. The establishment of this “seal line” is a function of gland design and seal crosssection which determines the correct amount of squeeze (compression) on the O-ring to maintain seal integrity without excessive deformation of the seal element.1. Excessive temperature developed causing the O-ring to harden and lose its elastic properties. An effective O-ring seal requires a continuous “seal line” between the sealed surfaces.

Wide clearance combined with side loads. Replace with a harder O-ring. for example. High pressure (in excess of system design or high pressure excursions). 2. more than 50% of the O-ring may be destroyed before catastrophic leakage is observed. Insure installation of proper size O-rings. extrusion and nibbling are caused by one or more of the following conditions: 1.
