SharkBite 1/2 in. Push-to-Connect Brass 45-Degree Elbow Fitting is the fastest way to connect PEX, Copper, CPVC, PE-RT, or HDPE pipe 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.
