Nibco Inc W01050D Copper Female Adapter 1/2 Inch Cxf

Product Description

The NIBCO INC W01050D is a lead-free copper female adapter fitting designed to transition a solder (sweat) connection to a female NPT threaded connection. Conforming to the C603 standard, this fitting features a solder cup end for a clean copper sweat joint on the 1/2 inch side and a female NPT thread on the 3/8 inch end. It provides a reliable, code-compliant method for adapting copper tubing runs to threaded pipe components in residential and light commercial plumbing systems. Licensed plumbers and pipefitters install this fitting wherever a copper line must terminate into a threaded valve, fixture supply, or manifold port.

This adapter is suited for potable water supply, hydronic distribution, and general plumbing applications where a solder-to-thread transition is required. The 1/2 inch by 3/8 inch CxF configuration is a common size for fixture supply connections, water heater hookups, and branch-line terminations. The lead-free construction meets federal and state drinking water compliance requirements for use in potable water systems.
