Uponor LF4545050 Propex Brass Coupling 1/2 Inch

Product Description

The UPONOR LF4545050 is a lead-free brass ProPEX coupling designed for joining 1/2-inch PEX tubing in potable water and hydronic piping systems. The ProPEX end style requires an expansion tool to enlarge the PEX pipe end and ring before insertion, creating a reliable, leak-resistant joint as the material returns to its original diameter. This coupling is manufactured domestically and is suitable for residential and light commercial plumbing applications where lead-free compliance is required by code.

This coupling is used in ProPEX-based plumbing installations, including hot and cold domestic water distribution, radiant heating, and snow-melt systems. It is a standard in-line fitting used when extending or repairing 1/2-inch PEX tubing runs. The domestic manufacture makes it suitable for projects with Buy American or domestic-content requirements.
