The Apollo PEX 12-Port PEX Manifold with 1/2 in. Brass Ball Valves is simple to install. Think of it as the circuit breaker for your water delivery system. The installation of an Apollo PEX manifold provides a single point flow control over each outlet. Apollo PEX manifolds are designed for implementation within home-run type PEX piping systems eliminating the need for additional fittings or connections between the water source and the point of use fixture. Apollo PEX manifolds are a key component of the most economical potable water piping systems. Also capable of integration into hydronic heating systems, Apollo PEX manifolds can be secured into place using copper crimps, stainless steel pinch clamps or stainless steel crimp sleeves (all sold separately). The Apollo PEX 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.
