PEX Stop Valves

Watts PEX Stop Valves are available in either straight or angle stop configurations. These PEX stop valves are used for point-of-use shut-off at the fixture. Both Pex Stop valves connect 1/2" PEX Tubing to 3/8" O.D. risers. The valves are full port and feature a quarter-turn shut-off. Compression inserts and rings for the 3/8" riser connections are included with the valves. These PEX valves may be used with the stainless steel clamping system or the copper crimp ring system.
