Float Shoes (FLOSHO) and Float Collars (FLOCOL) act on the same principle as our Bull Nose Plugs but with a non return (one way) valve and a heavier duty locking mechanism. The Float Shoe (Left) is used where long casing or rod strings are being used. It is inserted into end of rods with a flange. The Float Collar (Right) can be located inside any rod in the drill string. It is inserted into rod with a 2 way locking mechanism and non return (one way) valve.
