The SharkBite 1/2" push-to-connect x 3/8" male pipe thread dishwasher elbow is the easiest way to join copper, CPVC or PEX pipe in any combination with no soldering, clamps, unions or glue. Just insert the pipe and the stainless steel teeth bite down and grip tight, while a specially formulated O-ring compresses to create a perfect seal. Disassembly is just as fast using the simple disconnect tool (sold separately). So fittings and valves can be easily changed and reused. Get SharkBite, and get a grip on your next plumbing project.
