Nibco E022900 Cxm Dwv Threaded Cast Copper Fitting

Product Description

The NIBCO E022900 is a cast copper CXM DWV threaded piece fitting designed for drain, waste, and vent piping systems. It combines a solder cup inlet with a male NPT threaded outlet, allowing a transition from sweat-soldered copper tube to a threaded connection. When soldered to the end of the tube and paired with a slip joint nut and washer, the fitting provides a secure slip joint connection. Manufactured in an ISO 9001 certified facility, this fitting meets the quality and dimensional standards expected by licensed plumbers working in residential and light commercial DWV applications.

This fitting is used in drain, waste, and vent piping runs where a copper tube must terminate or transition to a threaded connection. It is suited for residential and light commercial plumbing installations where slip joint assemblies are required. The CXM configuration accepts a standard copper tube on the solder cup end and connects to NPT-threaded fittings, traps, or drain bodies on the male thread end. Plumbers working on fixture drain connections, trap assemblies, and vent tie-ins will find this fitting applicable to common rough-in and finish plumbing scenarios.
