Westlake Pipe Fittings dwv-d323-040 Dwv Pvc 1/8 Bend 4 in

Product Description

The WESTLAKE PIPE FITTINGS dwv-d323-040 is a 4-inch DWV PVC 1/8 bend, also commonly called a 45-degree street elbow. It features one hub (socket) end and one spigot end, allowing it to connect directly into another fitting without a coupling. Manufactured for non-pressurized drain, waste, and vent systems, this fitting redirects flow at a 45-degree angle with a smooth interior profile that minimizes debris buildup. Licensed plumbers and pipefitters install this fitting in residential and light commercial DWV systems as part of rough-in drain lines.

This fitting is intended for use in gravity-flow drain, waste, and vent piping where non-pressurized conditions apply. The street configuration — hub on one end, spigot on the other — makes it useful in tight spaces or back-to-back fitting arrangements where a standard elbow and coupling would add unnecessary length. Typical applications include sanitary drain lines, vent stacks, and horizontal branch connections in residential new construction and remodel projects.

Key Features

• 45-degree (1/8 bend) change of direction for gradual flow transitions in drain lines
• Street pattern: one hub end and one spigot end for direct fitting-to-fitting connections
• 4-inch nominal pipe size suits main drain lines and large branch connections
• Non-pressurized DWV rating for gravity-flow drain, waste, and vent applications
• PVC construction resists corrosion and chemical attack common in drain service

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 4-inch nominal PVC DWV piping systems operating under non-pressurized, gravity-flow conditions.

Installation Notes

Installation is performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local code. Before cutting into an existing drain line, confirm the system is out of service and any upstream cleanouts are accessible. Solvent-cement the hub end following ASTM D2564 procedures — prime both surfaces with approved PVC primer before applying cement, and allow full cure time before restoring flow. Do not use this fitting in pressurized supply or irrigation systems.
