The ApolloPEX 1/2 in. Chrome-Plated Brass PEX Barb x 3/8 in. Compression Quarter-Turn Dishwasher Tee Valve is a unique design that allows flow control to the outlet. Designed with retrofit dishwasher and water filtration installations in mind, simply cut the PEX pipe, install the tee using ApolloPEX fasteners and connect a standard 3/8 in. OD compression style water supply line to both the appliance and the valve and the project is complete. The 3/8 in. compression outlet provides the capability to install 3/8 in. O.D. tubing or 3/8 in. supply lines. It is designed for adding point of use fixtures such as dishwashers, toilets, faucets, ice makers, hot water dispensers and water filters to existing water supply systems. The ApolloPEX system is a comprehensive piping system comprised of brass fittings, poly alloy fittings, manifolds, valves, fasteners, tools and tubing designed for implementation in water delivery systems, simple or complex.
