Watts 1/2 in. x 3/8 in. CTS Push Fit Coupling

The Watts 1/2 in. x 3/8 in. CTS Push Fit Coupling works with copper, CPVC, PEX, LPDE, MPDE, HDPE, and polybutylene tubing in hot and cold water applications. It incorporates stainless steel gripping teeth in the collets, allowing the connectors to interconnect with multiple piping materials without special tools or tube inserts. Featuring an exclusive O-ring guide to ensure zero-leak connections, this coupling allows tube orientation to be changed with a simple twist to reduce the amount of tubing required. It is reusable and approved for use behind walls and underground.
