Rwc UC608LFA 3/4 in Male Sweat Brass Pex Barb Adapter

Product Description

The RWC UC608LFA is a 3/4-inch male sweat by 3/4-inch PEX barb adapter manufactured by SharkBite from lead-free DZR brass. This fitting connects copper pipe on the sweat end to PEX tubing on the barb end, serving as a transition point in potable water distribution and hydronic heating systems. The barb end is compatible with both stainless steel clamp systems and copper crimp ring systems, giving installers flexibility depending on the tooling on hand. Plumbers and pipefitters install this fitting as a low-profile, code-compliant solution when transitioning between copper and PEX in residential and light commercial plumbing.

This adapter is suited for residential and light commercial applications where a copper supply line transitions to a PEX distribution system. Common scenarios include retrofits of existing copper distribution lines, new construction rough-in where PEX runs extend from copper mains, and hydronic heating loops that tie into copper manifolds or boiler connections. The fitting is rated for potable water contact, making it appropriate for both domestic water supply and closed-loop heating systems.

Key Features

• Lead-free DZR brass construction meets NSF 372 requirements for low lead content
• 3/4-inch male sweat end connects to standard copper pipe using a torch and solder
• 3/4-inch PEX barb end accepts both stainless steel clamp rings and copper crimp rings
• Rated for potable water distribution and hydronic heating per NSF/ANSI 61
• Meets ASTM F1807 barb fitting dimensional and performance standards
• Sold individually, allowing quantity purchase to match job requirements

Compatibility

Designed for use in potable water distribution and hydronic heating applications. Compatible with PEX tubing secured with either a stainless steel clamp system or a copper crimp ring system, each sold separately.

Installation Notes

This fitting is installed by licensed plumbers or experienced pipefitters working under applicable plumbing codes such as the IPC or local equivalents. Shut off and drain the water supply before beginning work. The sweat end requires a torch, flux, and appropriate solder per local code; allow the joint to cool completely before pressurizing. The PEX barb end requires a separate clamp or crimp tool sized for 3/4-inch fittings — confirm tool compatibility with the ring system selected before installation.
