Tube fitting ferrule set inch size CFS-4 1 piece

The basic configuration consists of four parts: the fitting body, front ferrule, back ferrule, and nut, to which the tube is connected when in use. When in use, the two ferrules on the front and back work together to compensate for variations in tube outer diameter, wall thickness, material and hardness within the tolerance limits, always ensuring a superior leak-free connection. Hy-Lok tube fittings are manufactured under Hy-Lok Corporation's rigorous quality control program.
