These unique self-torquing fittings create a secure seal without the use of any tools. As the fitting is tightened, the resistance of the cap increases until the correct torque is reached. Fittings are made of PEEK™ and are compact in design and provide excellent chemical resistance.

The fitting can spin freely, eliminating tubing from twisting. A recess in the fitting houses the ferrule allowing maximum thread engagement with the port. Type S ferrule system uses a two-piece ferrule that fits permanently to the outside of the tubing. Two-part ferrule is made up of an inner PEEK or ETFE sealing surface surrounded by a stainless steel lock ring with only the inner portion in the fluid path.
