Westlake Pipe Fittings dwv-d107-251 Dwv Pvc Flush Bushing

Product Description

The WESTLAKE PIPE FITTINGS dwv-d107-251 is a DWV-pattern PVC flush bushing used to reduce pipe size within drain, waste, and vent systems. It accepts a 2-inch hub connection on one end and a 1-1/2-inch spigot on the other, allowing a transition from larger to smaller diameter pipe without adding length to the run. The flush bushing profile keeps the fitting compact inside the pipe assembly. Licensed plumbers and pipefitters install this type of fitting during rough-in and repair work on residential and light commercial DWV systems.

This bushing is suited for drain, waste, and vent piping applications where a 2-inch line must transition down to a 1-1/2-inch line. Common install scenarios include lavatory and kitchen sink drain connections, fixture branch lines, and stack transitions. The hub end receives a 2-inch spigot, and the spigot end inserts directly into a 1-1/2-inch hub fitting or pipe section downstream.

Key Features

• Flush bushing design keeps fitting compact within the pipe assembly
• Spigot x Hub end configuration for straightforward inline transitions
• DWV-rated PVC construction suitable for drain, waste, and vent service
• Reduces from 2 inches to 1-1/2 inches in a single fitting

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 2-inch x 1-1/2-inch DWV PVC piping systems using solvent-weld connections.

Installation Notes

Installation is performed by a licensed plumber in accordance with the International Plumbing Code or applicable local code. Shut off water supply and ensure the drain line is clear before beginning work. Use a approved PVC primer and solvent cement rated for DWV applications, following the manufacturer and code requirements for cure time before restoring flow. Do not apply mechanical stress to the fitting joint before the cement has fully cured.
