Apollo 1/2 in. Brass PEX-A Expansion Barb x Polybutylene Coupling

The Apollo ExpansionPEX 1/2 in. Brass PEX-A Barb Polybutylene Coupling is simple to install and designed for the transition from polybutylene pipe to PEX-A tubing. Apollo ExpansionPEX transition couplings must be secured into place Apollo ExpansionPEX sleeves or comparable expansion-type sleeve or ring (all sold separately). The Apollo ExpansionPEX system is a comprehensive cold expansion 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. A cold-expansion tool (sold separately) is required for installation.|Larger internal diameter of Apollo expansion PEX fittings results in a 25% greater flow rate within the system|Item is not compatible with PEXb pipe, crimp-style (ASTM 1807) or pinch clamp (ASTM F2098) piping systems|Constructed of lead free dezincification resistant (DZR) brass for superior reliability and strength|Meets or exceeds ASTM F1960 standard|Meets UPC, IPC, and cUPC standard requirements|Must secured in place using Apollo expansion PEX sleeves or other PEX-A expansion sleeves/rings (all sold separately)|NSF Listed|Barb x barb connection for PEX-A plumbing systems|Go/no-go gauges are never required|To ensure secure connections every time, fittings cannot be dry fit|Rated to 200 degree F and 200 psi
