Product Description CUT. PUSH. DONE. Used to join different size pipe together. Compatible with PEX, copper, CPVC, PE-RT and HDPE pipe in any combination and does not require soldering, gluing, crimping or the use of specialized tools for installation. 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. No soldering, no clamps, no glue. SharkBite products work with your existing plumbing, are easy to disassemble for changing and reusing fittings, and can be rotated for installation in tight spaces. Whether you need to repair a broken pipe or plumb a whole house, SharkBite provides a push-to-connect solution and leak-free results.
