Westlake Pipe Fittings P608-4 Pvc Reducing Coupling 8x4 in

Product Description

The WESTLAKE PIPE FITTINGS P608-4 is an 8 x 4 inch SDR-35 PVC reducing coupling designed for solvent weld installation in gravity-flow drainage and sewer systems. This fitting transitions a larger 8-inch pipe down to a 4-inch pipe in a single connection, eliminating the need for multiple adapters. Weighing 2.21 pounds, it is built to SDR-35 wall-thickness standards, making it appropriate for sewer lateral and storm drainage applications. Licensed plumbers and pipefitters are the typical installers for this type of fitting in both residential and light commercial projects.

This reducing coupling is suited for underground and above-grade gravity drainage systems where a change in pipe diameter is required along the run. Common scenarios include connecting a main sewer lateral to a smaller branch line or transitioning pipe sizes at a cleanout or junction point. The fitting accepts solvent cement bonding on both the 8-inch and 4-inch sockets, providing a leak-resistant, permanent joint rated for gravity sewer service.

Key Features

• Reduces from 8-inch to 4-inch pipe diameter in a single fitting
• SDR-35 wall thickness rated for gravity sewer and storm drain service
• Solvent weld sockets on both ends for a permanent, watertight bond
• PVC construction resists corrosion, root intrusion, and common sewer gases
• Lightweight at 2.21 pounds for easier handling during underground installation

Compatibility

Designed as an OEM-style replacement and new-installation fitting compatible with SDR-35 PVC pipe in 8-inch and 4-inch nominal diameters used in gravity sewer and storm drainage systems.

Installation Notes

Installation is typically performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local codes for sewer and drainage piping. Clean and deburr pipe ends before applying primer and solvent cement per the cement manufacturer's instructions. Ensure pipe is fully inserted to the socket stop and allow adequate cure time before backfilling or pressurizing the line. Do not use this fitting on pressurized supply systems.
