Rwc UC142LFA Sharkbite Pex Barb Adapter 1in Cf X 3/4in Mpt

Product Description

The RWC UC142LFA is a SharkBite PEX barb threaded male adapter designed to connect PEX tubing to a male NPT threaded fitting. Constructed from lead-free DZR brass, this adapter features a 1-inch CF (crimp/clamp) barb end and a 3/4-inch MNPT threaded end. It accepts both stainless steel clamp systems and copper crimp ring systems, giving installers flexibility in their connection method. Suitable for potable water distribution and hydronic heating applications, this fitting meets ASTM F1807, NSF/ANSI 61, and NSF 372 standards. Licensed plumbers and pipefitters are the primary installers for this type of fitting.

This adapter is suited for residential and light commercial plumbing systems where PEX tubing must transition to a threaded male connection. Common install scenarios include connecting PEX supply lines to valves, manifolds, or threaded ports on water heaters and hydronic heating equipment. It works with both potable water distribution systems and closed-loop hydronic heating applications, making it a versatile transition fitting for new construction and retrofit work alike.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off and depressurize the water supply before beginning work.
