The RWC UC374LFA is a 1 inch x 1 inch x 1 inch PEX barb tee fitting manufactured from lead-free DZR brass. It connects PEX tubing runs at a tee junction and is designed for reliable performance in both potable water distribution and hydronic heating systems. The barb configuration allows for a secure, low-profile connection when used with a stainless steel clamp ring system or a copper crimp ring system. Licensed plumbers and experienced installers use this fitting as a straightforward, cost-effective solution wherever a branch connection is needed in a PEX line.
This fitting is suited for residential and light commercial applications involving PEX tubing. It performs in potable water distribution systems as well as closed-loop hydronic heating installations. The barb design works with standard stainless steel clamp systems and copper crimp ring systems, giving installers flexibility to use their preferred connection method. Clamp rings and crimp rings are sold separately. The fitting is sold individually.
Designed for use with 1 inch PEX tubing in stainless steel clamp ring or copper crimp ring systems approved for potable water distribution and hydronic heating applications per ASTM F1807.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line before cutting into any existing piping. Use a dedicated PEX clamp or crimp tool rated for the connection system being used. Do not overtighten or reuse clamp rings once crimped or clamped.
