Learn how to make push-to-connect installations with SharkBite 1-1/4 and 2-inch fittings, ideal for commercial new construction applications. SharkBite fittings are compatible with PEX, copper, CPVC, PE-RT and HDPE pipe. Installations with PEX, PE-RT, and HDPE pipe require tube stiffeners, sold separately. Like traditional brass SharkBite installations, these fitting sizes will require the insertion depth chart and a correctly sized disconnect clip for fitting adjustments. Using SharkBite is fast, efficient and reliable.
