For applications where self-filling float equipment is used. Reduces the risk of stuck casing by eliminating down-time to fill casing Ability to immediately circulate casing by engaging element creates a safer working environment by eliminating the need to install a pump-in swage. Also allows for immediate well control by circulating heavier fluids as needed. 0 H O S E AD A P T E R 2 2 .0 S E A L R E T A IN E R R IN G S E A L IN G E L E M E N T G A U G E R IN G R E T A IN E R S U B 14' 3" (O V E R A L L ) 7 3 .0 0 6 .3 M U D S A V E R S U B 1 3 .2 N O S E G U ID E C O N E .0 M AN D R E L 4 .0 D R IL L P IP E C O N N E C T O R S U B 2 4 .C O M PO N E N T S O F FA C T O O L 1 2 .0 F L E X IB L E H O S E 4 .0 0 6 .0 0 7 .
