Designed for burst and/or frozen pipe breaks, pinhole leaks, and other situations when pipe movement is restricted, the connector fitting allows for repairs in a confined area. They require no tools to make secure, leak-proof connections and can be used with copper, PEX or CPVC pipe. The fittings are not suitable for potable water applications. 973-808-5600; www.johnguest.com.
