Westlake Pipe Fittings dwv-d302-040 Dwv Street Elbow 4 in

Product Description

The WESTLAKE PIPE FITTINGS dwv-d302-040 is a 4-inch, 90-degree PVC street elbow rated for drain, waste, and vent (DWV) applications. It connects with a hub end on one side and a spigot end on the other, allowing it to fit directly into another hub without a coupling. Built to Schedule 40 standards, this fitting handles the directional changes common in residential and light commercial drain systems. Plumbers reach for this part when routing waste lines through tight spaces or changing pipe direction at fixtures and cleanouts.

This fitting is intended for gravity-flow DWV piping systems in residential and commercial construction. The hub x spigot configuration makes it well suited for back-to-back or stacked fitting runs where eliminating a coupling saves space inside walls, floors, or ceiling chases. It is compatible with standard 4-inch PVC DWV pipe and solvent-weld fittings conforming to Schedule 40 dimensions.

Key Features

• 90-degree sweep supports proper drainage slope in DWV piping layouts
• Hub x spigot end configuration eliminates the need for an additional coupling when connecting into a hub fitting
• Schedule 40 wall thickness meets standard DWV pressure and load requirements
• PVC construction resists corrosion and buildup from household and light commercial waste streams
• 4-inch nominal size fits common main drain and stack applications

Compatibility

Designed as an OEM-style replacement and standard new-installation fitting for 4-inch Schedule 40 PVC DWV piping systems using solvent-weld connections.

Installation Notes

Installation is performed by licensed plumbers in accordance with the International Plumbing Code (IPC) and applicable local codes. Before cutting into an existing drain line, isolate the section and clear standing water. Clean and dry all mating surfaces, apply an approved PVC primer, then solvent-weld with a listed PVC cement rated for DWV service. Allow full cure time before restoring flow or covering the installation.
