The NIBCO INC W01240T is a 3/4 inch CxM male adapter designed to transition a copper sweat (solder cup) connection to a male NPT threaded connection. Built to lead-free standards, this fitting is suited for potable water systems where compliance with lead-free requirements is mandatory. The solder cup end accepts standard 3/4 inch copper tubing, while the male NPT thread end connects directly to female-threaded valves, nipples, or other threaded components. It is a standard catalog item sold in packages of 25 units and is installed by licensed plumbers in both residential and light commercial piping systems.
This adapter is used wherever a copper sweat line must terminate into a threaded fitting — common in water supply rough-in, fixture connections, valve installations, and equipment hookups. It is appropriate for residential potable water distribution as well as light commercial plumbing applications. The lead-free construction makes it suitable for use in drinking water systems governed by state and federal lead-free mandates.
Designed as an OEM-style replacement and standard-use adapter for 3/4 inch copper sweat to male NPT threaded plumbing connections in residential and light commercial water supply systems.
Installation is performed by a licensed plumber. Shut off water supply and depressurize the line before soldering. Clean and flux the copper tube end before sweating the solder cup connection per standard practice. Apply pipe thread sealant or PTFE tape to the male NPT threads before making the threaded connection. Follow applicable IPC and local plumbing codes for potable water systems.
