CUT. PUSH. DONE. Innovative push-to-connect design makes for quick and easy installation. Connect two pieces of PEX, copper, CPVC, PE-RT and/or HDPE pipe in any combination. Ideal for working in tight spaces. Faster install time and ease of use reduces installation errors. The SharkBite Connection System makes any plumbing project fast and easy thanks to unique push-to-connect technology. When you insert a pipe into a SharkBite quick-connect fitting, the fitting’s stainless-steel teeth bite down and grip the pipe, while its special O-ring compresses to create a watertight seal.
