Dibafit gripper fitting system uses a one-piece ferrule that permanently attaches to the outside of semi-rigid tubing. The fitting can spin freely, preventing tubing from twisting. Select from polypropylene (PP), ETFE, or PEEK fittings. PP fittings are available in 10 different colors for easy identification. Mixed pack includes all 10 colors. ETFE and PEEK fittings provide excellent chemical resistance. PEEK fittings withstand higher temperatures and are available in compact or standard head.
