Westlake Pipe Fittings dwv-d107-338 Dwv Flush Bushing

Product Description

The WESTLAKE PIPE FITTINGS dwv-d107-338 is a PVC flush bushing designed for drain, waste, and vent (DWV) piping systems. It reduces a 3-inch spigot connection down to a 2-inch hub, allowing technicians to transition between pipe sizes within a DWV assembly. Constructed from PVC, it is lightweight, corrosion-resistant, and compatible with standard solvent-weld installation methods. Plumbers and pipefitters install this fitting during rough-in and finish plumbing on both new construction and retrofit projects where pipe size reductions are required in gravity-drain configurations.

This fitting is suited for residential and light commercial DWV applications. The spigot end inserts into an existing 3-inch hub fitting, while the 2-inch hub accepts standard 2-inch PVC pipe or spigot fittings. It is commonly used in horizontal drain runs, vertical stacks, and vent piping assemblies where a flush-style bushing provides a compact, low-profile transition without adding significant stack height. No separate adapter is required for this reduction.

Key Features

• Flush bushing design provides a compact in-line size reduction with minimal added length
• Spigot x hub end configuration for direct integration into standard DWV assemblies
• PVC construction resists corrosion and chemical degradation common in drain and waste service
• 3-inch to 2-inch nominal pipe size reduction for common stack and branch transitions
• Solvent-weld connection on both ends for a permanent, leak-resistant joint

Compatibility

Designed as an OEM-style replacement or new-installation fitting for residential and light commercial PVC DWV piping systems using 3-inch and 2-inch nominal pipe sizes.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off the water supply and ensure the drain line is depressurized and clear before cutting into an existing system. Clean and deburr pipe ends, apply an appropriate PVC primer, and follow with PVC solvent cement per the cement manufacturer's instructions. Allow adequate cure time before restoring flow to the line.
