A.Y. McDonald’s Push-Fit Valves & Fittings connect to copper tubing, PEX tubing and/or CPVC pipe. Pipe/tube end preparation is not required with the use of the beveled stiffeners supplied with the fittings. No soldering, crimping or solvent welding is necessary due to the special rubber gasket and stainless steel grip ring in the socket end. Produced from low lead forged brass, the fittings are ideal for above-ground plumbing, water systems and hydronic heating systems.
