Uponor LF4521515 Male Adapter 1-1/2 in Pex X Mnpt Brass

Product Description

The UPONOR LF4521515 is a lead-free brass male adapter designed to transition from PEX tubing to a male NPT threaded connection. At 1-1/2 inches, this fitting is sized for main distribution lines and larger branch runs found in residential and light commercial plumbing systems. The brass construction delivers long-term corrosion resistance, and the lead-free designation meets current federal and state potable water compliance requirements. Licensed plumbers and pipefitters install this adapter when connecting PEX distribution lines to threaded metal valves, manifolds, or other threaded components.

This adapter is suited for potable water supply systems, hydronic heating distribution, and radiant floor applications where PEX tubing terminates at a threaded fitting. The 1-1/2-inch size is commonly found at water heater connections, main shutoffs, and larger zone feeds. Domestic manufacturing supports traceability requirements on commercial projects where Buy American provisions apply.

Key Features

• Lead-free brass construction meets federal Safe Drinking Water Act requirements for potable water use
• 1-1/2-inch PEX x MNPT configuration transitions PEX tubing to male threaded pipe connections

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/2-inch PEX plumbing systems requiring a transition to male NPT threaded connections.

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 making any connections. Apply thread sealant tape or pipe dope to the male NPT threads before engaging the mating female fitting. Follow the PEX system manufacturer instructions for the appropriate expansion or crimp connection method at the PEX end.
