Uponor LF2935050 1/2 Inch Pex Brass X C Straight Stub

Product Description

The UPONOR LF2935050 is a straight stub fitting designed for use in PEX piping systems. It connects PEX tubing to copper pipe using a PEX Brass x C (sweat copper) end configuration, making it a reliable transition fitting for residential and light commercial plumbing installations. The 1/2-inch nominal size is one of the most common sizes in domestic water distribution. The lead-free brass construction meets drinking water safety requirements, making it appropriate for potable water applications. Licensed plumbers and pipefitters install this fitting in new construction and retrofit work where PEX meets existing copper infrastructure.

This fitting is used in residential and light commercial domestic water distribution systems where PEX tubing must interface with copper supply lines. The straight stub profile makes it well suited for tight spaces and direct connections without the need for additional adapters. It is a practical choice for plumbers transitioning from copper to PEX in remodel or repair scenarios, as well as for new PEX rough-in work that ties into existing copper stub-outs.

Compatibility

Installation Notes

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 beginning work. The copper sweat end requires standard soldering tools and flux; follow safe soldering practices and allow joints to cool fully before restoring water pressure. The PEX end must be installed using the appropriate expansion or clamp tool specified for the PEX system in use.
