Sharkbite UC058LFA Pex Barb Reducing Coupling 3/4 X 1/2 Inch

Product Description

The SHARKBITE UC058LFA is a PEX barb reducing coupling designed to connect PEX tubing in potable water distribution and hydronic heating systems. Constructed from lead-free DZR (dezincification-resistant) brass, this fitting transitions from 3/4 inch to 1/2 inch tubing. The barb design creates a secure, low-profile connection when used with either a stainless steel clamp system or a copper crimp ring system. Clamps and crimp rings are sold separately. Licensed plumbers and pipefitters install this fitting in residential and light commercial piping runs where a reducing connection between different PEX tubing sizes is required.

This coupling is suited for potable water distribution lines and hydronic heating applications. The lead-free DZR brass construction meets certification requirements for drinking water contact surfaces. It works within both the stainless steel clamp and copper crimp ring installation methods, giving installers flexibility based on their preferred tooling. The fitting is sold individually, making it practical for service calls and small repairs as well as new construction projects.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line before cutting and fitting. Use the appropriate PEX clamp tool or copper crimp tool along with the correct ring size for the tubing dimension being connected. Do not overtighten crimp rings beyond tool-rated closure to avoid fitting damage.
