SharkBite push-to-connect slip fittings are the fastest way to connect copper or CPVC in any combination. No soldering, clamps, unions, glue, or special tools required. Simply insert the pipe and the teeth bite down and grip tight, while a specially formulated O-ring compresses to create a watertight seal. Changes can easily be made by rotating the fitting after installation. Removing the fitting is just as fast using a disconnect tool so fittings and valves can be easily changed or reused. Designed with stainless steel gripping teeth for a secure connection, chlorine-resistant O-ring for a long-lasting seal and backed by a 25-year warranty.
