Uponor LF4541010 Propex Brass Coupling 1 Inch

Product Description

The UPONOR LF4541010 is a 1-inch nominal ProPEX brass coupling designed for use in PEX piping systems. This fitting connects two sections of 1-inch PEX tubing using the ProPEX expansion method, where a ProPEX tool expands the tubing end before the fitting is inserted and the tubing contracts to form a secure, leak-resistant joint. Constructed from lead-free brass, this coupling meets domestic sourcing requirements. It is a standard component installed by licensed plumbers in both new construction and retrofit applications.

This coupling is suited for residential and light commercial plumbing installations where ProPEX-style PEX piping is specified. It is commonly used in water supply distribution systems, including hot and cold potable water lines. The ProPEX expansion connection method is widely used in hydronic and domestic water applications where a reliable, tool-driven mechanical joint is preferred over crimp or clamp alternatives.

Installation Notes

Installation requires a calibrated ProPEX expansion tool sized for 1-inch tubing. Licensed plumbers should shut off the water supply and depressurize the line before beginning work. All installations must comply with applicable local plumbing codes and IPC requirements. Allow adequate expansion ring seating time as specified by system installation guidelines before pressurizing the system.
