Constructed from polymer, this fitting delivers corrosion resistance and reliable performance in residential and light commercial plumbing applications. Each bag contains 25 couplings, making it practical for contractors running multiple drops or supply lines in a single job. The barb design creates a secure, watertight connection when used with the appropriate clamp or crimp ring per the tubing manufacturers recommendation.This coupling is suited for new construction and retrofit plumbing work where PEX tubing size changes are needed within a distribution system. Typical applications include reducing a 3/4-inch trunk line to a 1/2-inch branch line feeding fixtures such as sinks, toilets, or shower valves. The 25-piece bag format is well suited to rough-in work on residential homes, multi-unit buildings, and light commercial plumbing projects where multiple reductions are required.Key FeaturesReduces 3/4-inch PEX to 1/2-inch PEX in a single fittingPolymer construction resists corrosion and scale buildupBarb-style end connections compatible with standard PEX clamp and crimp tools25 couplings per bag for efficient job-site inventory managementSuitable for potable water and hydronic distribution pipingCompatibilityDesigned as an OEM-style barb fitting for use with standard 3/4-inch and 1/2-inch PEX-A, PEX-B, and PEX-C flexible tubing in residential and light commercial plumbing distribution systems.Installation NotesInstallation is performed by licensed plumbers in accordance with local plumbing codes and IPC guidelines for PEX piping systems.
