The SharkBite UR016A4 Push-to-Connect Flexible Water Connector provides a fast, tool-free solution for connecting water supply lines to toilets, faucets, water heaters, and other plumbing fixtures without soldering or special skills. SharkBite’s patented push-to-connect technology allows the fitting to be installed on copper, PEX, CPVC, or PE-RT pipe simply by pushing the pipe end firmly into the fitting until it locks. The flexible stainless steel braid outer sleeve withstands water pressure and resists kinking, while the inner EPDM rubber lining is safe for potable water applications. Lead-free and NSF-certified for use in hot and cold water systems, the UR016A4 is a professional-grade connector that simplifies both new installations and repairs in residential plumbing.
