The SharkBite Connection System offers an extensive line of barb fittings plus manifolds, supports and tools for both clamp and crimp ring PEX tubing installations. When a water distribution project requires low cost materials, a system that utilizes PEX tubing, barb fittings and manifolds is a good choice. In addition to being cost effective, these systems simplify the installation compared to copper or rigid plastic pipe systems that use solder or glue for fitting joints. The SharkBite PEX/Barb System includes everything needed, from pressure regulators and valves with barb connectors, to chrome plated stops for hooking up fixtures. Material: Brass.
