SharkBite Elbows allow the user to connect any combination of copper, PEX CPVC, or PE-RT pipe together to form a 90-degree connection. With no soldering, clamps, unions or glue required, it's as simple as inserting the pipe into the fitting deep enough to be sealed by our specially-formulated O-ring. Once inserted, the stainless steel teeth bite down and grip the pipe. This push-to-connect fitting is designed for potable water and radiant heating (including underground or behind-the-wall) applications with no access panels required. It is rated up to 200°F and 200 psi.
