Uponor LF4512020 Adapter 2 Inch Pex X C Brass

Product Description

The UPONOR LF4512020 is a 2-inch PEX-to-copper (PEX x C) transition adapter manufactured from lead-free brass. It is designed to connect PEX tubing directly to copper pipe systems, making it a standard fitting for residential and light commercial plumbing installations. The lead-free brass construction meets current potable water compliance requirements. Licensed plumbers install this adapter during new construction, system expansions, or remodel work where PEX and copper piping must interface at a 2-inch connection point.

This adapter is suited for potable water distribution systems where a transition from PEX tubing to copper pipe is required at a 2-inch diameter. It is typically used in main supply lines, branch manifold connections, or service entry points where system designers specify a PEX-to-copper crossover. The domestic designation confirms the fitting is manufactured for use in U.S. potable water applications.
