CUT. PUSH. DONE. Cap off pipes in seconds with the SharkBite Push-to-Connect 1/2 Inch End Cap. This plumbing fitting caps copper, PEX, CPVC, HDPE, or PE-RT pipe. With no soldering, clamps, or glue required, capping is as simple as inserting a pipe into the fitting deep enough to be sealed by the specially-designed O-ring. The SharkBite Connection System makes any plumbing project fast and easy with our unique push-to-connect technology. When you insert a pipe into the SharkBite quick connect fittings, the stainless-steel teeth bite down and grip the pipe, while the specially formulated O-ring compresses to create the perfect watertight seal. SharkBite push connect fittings are the no fuss way to fix small leaks or plumb a whole house. Whether you need to repair a broken pipe or plumb a whole house, SharkBite fittings are the push-to-connect solution for leak-free results.
