BrassCraft’s Push Connect high-performance stops needs no special preparation. Just make sure the tube is cut square and free of burrs before installing the stop to help ensure a quick, leak-free connection. It is compatible with PEX, copper and CPVC. A pre-inserted tube stiffener makes it a faster connection. No installation tools are required; no soldering or gluing is needed to install. The stops are offered in straight and angle configurations and are no-lead compliant.
