3515r-1008 Pex Quick Connect Tube Coupling, 1/2 X 3/8 In.

This push-fit tube coupling makes fast, tool-free connections between PEX, copper, CPVC, and other flexible tubing without special tools or tube inserts. The Watts 3515R-1008 is ideal for new plumbing installations, repairs, and service work where speed and reliability matter. It eliminates the need for assembly, soldering, or crimping, reducing labor time and the risk of leaks.

The coupling incorporates stainless steel gripping teeth in the collets that securely hold multiple tubing materials, while an exclusive O-ring guide ensures zero-leak connections. Its reusable design and code approval for behind-wall and underground installation make it suitable for both visible and concealed applications. The tube orientation can be changed with a simple twist, reducing the amount of tubing required in complex plumbing layouts.
