No Twist One-Piece Fittings – High Pressure PEEK

PEEK nuts
No-Twist one piece fittings
close move

Our patented* no twist fittings for 1/16" and 1/32" tubing offer the convenience of a one-piece fitting while solving a problem inherent to such designs. In other one-piece designs, the ferrule rotates against the fitting detail, creating particulates. The no twist design has a separate ferrule that snaps into the nut, so it's attached but still free to avoid rotation during tightening.

Since the ferrule is not machined onto the nut, it can be made from a different material. PEEK nut with PEEK ferrule, or PEEK nut with CTFE ferrule — the possibilities are endless.
