When reducing pipe size, there is no easier way than with SharkBite’s EvoPEX push-fit reducing couplings. Easily reduce from 3/4” to 1/2”. There is no need for solder, glue, clamps or unions – simply push-to-connect and move on. It’s as simple as inserting PEX pipe into the fitting deep enough to be sealed by our specially-formulated O-ring. Once inserted, the stainless steel teeth bite down and grip the pipe. A green indicator ring will display in the slots around the fitting to visually show the secured permanent inner-diameter connection.This quick-connect fitting is designed to make PEX-to-PEX connections in potable water and radiant heating (including underground or behind-the-wall) applications with no access panels required. Fittings are rated to 80 psi @ 200°F, 100 psi @ 180°F, and 160 psi @ 73.4°F.
