What is a two-ferrule compression fitting?

Two-ferrule compression fittings is coupling method used to connect two pipes, instrumentation or valves. It consists of a compression nut, back ferrule, front ferrule and fitting body. The pipe slid through the nut and ferrules and the nut is tightened down, from the finger tight position the nut is rotated for 1-1/4 turn. The installation sequence is fitting body (seat), Front ferrule (big ferrule), Back ferrule (smaller one) and the compression nut. Front ferrule crates sealing against tubing outside diameter and the fitting body while the back ferrule axially pushes the front ferrule and applies a radial grip on the tube.

The application covers a wide range of industries such as household, automotive, oil & gas, mining, chemical & petrochemical, semiconductors, pneumatic and hydraulic systems
