Rwc UC134LFA10 Sharkbite Brass Pex Barb Adapter 3/4 in

Product Description

The RWC UC134LFA10 is a SharkBite PEX barb threaded male adapter designed for fast, reliable connections in PEX tubing systems. Constructed from lead-free DZR brass, this fitting features a 3/4 inch CF (crimp/clamp) barb inlet on one end and a 3/4 inch male NPT (MNPT) threaded outlet on the other. It is approved for potable water distribution and hydronic heating applications. The fitting is compatible with both stainless steel clamp ring and copper crimp ring installation methods, making it a flexible option for plumbers working across different jobsite conditions. Clamp and crimp rings are sold separately.

This adapter is suited for residential and light commercial plumbing installations where PEX tubing must transition to a threaded male connection. Typical applications include potable water supply lines and hydronic heating distribution loops. The MNPT end connects directly to standard female-threaded fittings, valves, and manifolds. Its lead-free DZR brass construction meets current NSF and ASTM standards for water contact applications, making it appropriate for any jurisdiction requiring NSF 372 lead-free compliance.

Installation Notes

Installation is performed by a licensed plumber following applicable IPC or local plumbing code requirements. Shut off the water supply and depressurize the line before making any connections.
