The Apollo Expansion PEX 1/2 in. Plastic PEX-A Barb Tee (5-Pack) is simple to install. Apollo Expansion PEX poly alloy fittings are the perfect alternative to brass in regions where water quality can negative affect brass. Apollo PEX barb fittings are a key component of the most economical potable water piping systems. Also capable of integration into hydronic heating systems, Apollo Expansion PEX couplings must be secured into place using a Apollo Expansion PEX sleeve or comparable cold expansion-type sleeve or ring (all sold separately). The Apollo Expansion PEX 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. Pro pack includes 5-fittings Larger internal diameter of Apollo expansion PEX fittings results in a 25% greater flow rate within the system Constructed of high density polysulfone alloy for superior reliability and strength Cold-expansion tool (sold separately) is required for installation Meets or exceeds ASTM F1960 standard Meets UPC, IPC and cUPC standard Must secured in place using Apollo expansion PEX sleeves or other PEX-A expansion sleeves/rings Go/no-go gauges are never required Barb x barb x barb connection for PEX-A plumbing systems To ensure secure connections every time, fittings cannot be dry fit Rated to 200F and 200 psi Item is not compatible with PEXb pipe, crimp-style (ASTM 1807) or pinch clamp (ASTM F2098) piping systems Dimensions Double Fitting Size 1/2" x 1/2" Fitting 1 size 1/2" Fitting 2 size 1/2" Fitting 3 size 1/2" Fitting Size Dimensions 1/2" x 1/2" x 1/2" Product Height (in.) 1.44 in Product Width (in.) 2.44 in Single Fitting Size 1/2" Triple Fitting Size 1/2" x 1/2" x 1/2" Details Application Potable Water Color Family Black Color/Finish Black Compatible Pipe Material PEX Connection 1 Barb Connection 2 Barb Connection 3 Barb Connectivity Barb Features Corrosion Resistant, Lead Free, Removable Fitting or Connector Type Tee Fitting/ Connector Collection PEX Material Plastic Maximum working pressure (psi) 200 Maximum Working Temperature (F) 200 Pack Size 10 PEX Fitting Type Expansion PEX Type A Pipe or Fitting Product Type Fittings Connectors Product Weight (lb.) 0.02 lb Reducing Fitting No
