Keeney's quarter turn repair valves offer a simple solution for failed valves. Over time the internal parts of a valve can corrode and cause the valve to freeze up making it impossible to close. An existing valve can be difficult to remove and could involve cutting the pipe that the valve is connected to. Keeney's repair valves attach to the outlet of your existing failed valve using a compression connection and a captured nut and acts as the new valve; eliminating the need to remove or cut the old valve off. All repair valves are quarter turn and feature a solid chrome plated brass ball and stem, brass forged body, and Teflon seats. Available in 2 sizes; 3/8" O.D. x 3/8" O.D. and 1/2" F.I.P. x 3/8" O.D.
