The SharkBite straight coupling is the easiest plumbing fitting to join any combination of Copper, PEX, CPVC, PE-RT or SRD9 HDPE pipe together. 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 the 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 applications with no access panels required. It is rated up to 200 degree Fahrenheit and 200 PSI.
