Charlotte Pipe PVC-102-3X4 Pvc Dwv Increaser Reducer 3x4

Product Description

The CHARLOTTE PIPE PVC-102-3X4 is a PVC DWV increaser reducer coupling designed for drain, waste, and vent piping systems. This fitting transitions between 3-inch and 4-inch pipe diameters in gravity-fed, non-pressure drainage applications. Rated for use in systems where temperatures do not exceed 140 degrees F, the fitting is lightweight and accepts standard solvent cement joining. Plumbers and pipefitters install this type of coupling when connecting different pipe sizes within a DWV stack or branch line. No special cutting tools are required, and the fitting is also compatible with threading, flanging, and roll-grooved joining methods.

This increaser reducer is suited for residential and light commercial drain, waste, and vent installations where a diameter change is needed between a 3-inch branch and a 4-inch main line or stack. Typical applications include connecting lavatory or sink drains into larger soil stacks, or upsizing a vent run where code requires a larger diameter. Manufactured in the USA by Charlotte Pipe, it meets the expectations of licensed plumbers working to IPC and UPC code requirements.
