Flareless compression fittings are used to terminate hydraulic tubing ends or allow them to connect to other hydraulic tubing. They come in straights, 90 degree elbows, 45 degree elbows, tees, branch tees, run tees and crosses.

Dual Ferrule versus Single Ferrule

Most compression tube manufacturers will use dual or single ferrule configuration to lock tubing to the fittings. Swagelok, Parker, SSP, and Weatherhead flareless compression fittings will use a dual ferrule combination whereas Tylok and Tompkins will use a single ferrule combination.
