Nibco Inc W01290T Cxm Adapter 1-1/2 Inch Lead-free

Product Description

The NIBCO INC W01290T is a 1-1/2 inch copper-to-male adapter designed to transition a solder (sweat) cup connection to a male NPT threaded connection. Also referenced as the U604, this fitting is manufactured lead-free, meeting the requirements for potable water applications. It is a standard component in copper plumbing systems where a sweat-joined pipe run must terminate or connect at a threaded fitting, valve, or equipment port. Plumbers and pipefitters install this adapter in residential and commercial plumbing, hydronic heating, and mechanical systems wherever a copper line must interface with a threaded component.

This adapter is suited for use in water supply lines, hydronic piping, and other copper plumbing applications requiring a solder-to-thread transition. The 1-1/2 inch size fits standard copper tubing and mates with 1-1/2 inch male NPT threads. Its lead-free construction makes it appropriate for drinking water systems subject to lead-free compliance requirements under applicable plumbing codes.

Compatibility

Designed as an OEM-style replacement and standard-use fitting for 1-1/2 inch copper plumbing systems requiring a solder cup to male NPT threaded transition.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters. The copper solder cup end is joined using standard sweat-soldering technique — clean and flux all mating surfaces before applying heat, and ensure the pipe and fitting are dry before soldering. The male NPT threads should be wrapped with thread seal tape or pipe thread compound before assembly into a female threaded fitting or valve. Always shut off and depressurize the water supply and drain the line before beginning work, in accordance with applicable local plumbing codes.
