Westlake Pipe Fittings dwv-d107-532 Dwv Pvc Flush Bushing

Product Description

The WESTLAKE PIPE FITTINGS dwv-d107-532 is a 6-inch x 4-inch flush bushing designed for drain, waste, and vent (DWV) piping systems. Constructed from white PVC, this fitting features a spigot end on the 6-inch side and a hub end on the 4-inch side, allowing a transition from a larger pipe to a smaller pipe within a DWV assembly. The flush bushing profile keeps the fitting compact and seated cleanly within the adjoining hub. Plumbers and pipefitters use this type of bushing when reducing pipe diameter inline without requiring a separate coupling or adapter.

This bushing is suited for residential and light commercial drain, waste, and vent applications where a 6-inch line must transition down to a 4-inch line. Typical installations include building drain reductions, stack transitions, and branch connections in gravity-flow DWV systems. The spigot x hub configuration allows the fitting to slide directly into a standard 6-inch DWV hub while accepting a 4-inch pipe or fitting into its own hub end.

Key Features

• Flush bushing design reduces bulk and sits flat within connecting hub
• Spigot x hub end configuration for inline diameter reduction
• White PVC construction suited for DWV service conditions
• 6-inch to 4-inch reduction for gravity-flow drain and vent lines
• Compatible with standard DWV solvent-weld fittings and pipe

Compatibility

Designed as an OEM-style replacement and standard-fit component for residential and commercial PVC DWV piping systems using solvent-weld connections.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off water flow and verify the line is depressurized before cutting into any existing DWV assembly. Use approved PVC DWV primer and solvent cement rated for the pipe schedule and service type. Do not apply solvent cement in enclosed spaces without adequate ventilation.
