3 in PVC DWV Female Adapter

This Mueller Industries fitting joins a 3-inch female NPT thread to a hub connection in drain waste and vent systems. The Schedule 40 PVC body meets ASTM D1784 cell class 12454 for consistent material quality. Its white finish identifies the piping network at a glance.

DWV installers needing a thread-to-hub transition

The adapter handles the change from threaded pipe to a hub socket in gravity-flow drainage. It is not rated for pressurised lines so installers working on water supply or compressed air must choose a pressure-class component instead.

Maximum service temperature 140 degrees F

The PVC material is certified for continuous use up to 140 degrees Fahrenheit. Systems that routinely exceed this temperature require a higher-temperature piping material.
