A bite type fitting is sometimes incorrectly referred to as a compression fitting. Compression fittings are designed for use with soft tubing and are not interchangable with bite type fittings!

The Ferulok bite type fitting is a flareless fitting that consists of a body, a one-piece precision machined ferrule, and a nut. On assembly, the ferrule “bites” into the outer surface of the tube with sufficient strength to hold the tube against pressure, without significant distortion of the inside tube diameter. The ferrule also forms a pressure seal against the fitting body.

Parker Ferulok fittings allow the fitting assembler to visually inspect the bite quality, thus significantly minimizing the risk of improper assembly and related service problems.
