The SharkBite 1/4" push-to-connect x 3/4" garden hose thread 90° dishwasher elbow is the easiest way to join copper, PE-RT, 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.
