The 1/2" x 8" Copper Pipe Push-Fit Stubout Elbow allows for the plumbing to be roughed in, dry walled and painted. Once ready to install the fixture simply cut the copper stubout and attach necessary fitting to and complete the job. Clamps secure the SharkBite fitting to a joist and the push-to-fit 1/2" Sharkbite fitting 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 so fittings and valves can be easily changed and reused.
