This 1/16” fingertight fitting is 1.07” (27.2 mm) long and comes with a CTFE ferrule. Short and medium lengths are also available.
VICI’s patented no-twist fittings are designed with a separate ferrule that snaps into the nut, so it is attached but will not rotate during tightening, thus avoiding the particulates commonly created with other one-piece fittings.
Sold in packages of 5. Since the ferrule is not machined onto the nut, it can also be made from a variety of materials including FEP, PFA, PTFE, CTFE, glass-filled PTFE, and glass-filled PEEK.
