This Quick Connect fitting incorporates stainless steel gripping teeth in its collet. These corrosion resistant teeth allow these fittings to interconnect with multiple materials without the need for special tools or tube inserts. After a joint is made, the tubing can still swivel while connected, even under maximum pressure. Easy installation, reusable, works with hot and cold water, can be used with PEX, CPVC, PB or copper tubing.
