Polyalloy Plugs for PEX Systems Polyalloy plugs are used to pressure test a PEX system or to cap, either permanently or temporarily, a PEX water line. These Advanced Polymer (plastic) fittings are perfect for highly corrosive applications. This 3/4" Polyalloy Plug Fitting is compatible with 3/4" PEX tubing and is typically used in conjunction with a copper crimp ring or stainless steel clamp ring. This fitting maintains a tight seal and resists corrosion due to its state-of-the-art plastic alloy construction. The maximum working pressure/temperature is 200 PSI/200°F, so this coupling will hold up in high pressure, hot water applications. Product Specifications: Size: 3/4" Connections: Barb Material: Plastic Polysulfone Max Pressure: 200 PSI Max Temperature: 200°F Compatibilities: 3/4" PEX Tubing
