(1/2 — 3/4 in.) Reduce installation times with ProLock and Speedfit CTS valves.

Copper, CPVC or PEX Shut-Off Valves

John Guest push-fit, shut-off valves feature Twist-to-Lock technology, which creates easy, secure installations. These CTS valves come in two models; ProLock and Speedfit Shut-Off Valves. Both copper, CPVC or PEX shut-off valves are available in 1/2 inch and 3/4 inch sizes and require no tools, soldering, glue, or clamps to install. They can also be removed easily without pipe damage. Our small water shut-off valves can be installed with copper, PEX or CPVC pipes and are available with hot and cold color-coding caps.
