SharkBite® elbows allow the user to connect any combination of copper, PEX CPVC or PE-RT pipe together to form a 90 deg 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 deg F and 200 psi.
