Westlake Pipe Fittings P157-4 SDR-35 Pvc Sanitary Tee

Product Description

The WESTLAKE PIPE FITTINGS P157-4 is a 6 x 4 inch SDR-35 PVC sanitary tee designed for solvent weld installation in gravity-flow drainage systems. This fitting connects a 4-inch branch line into a 6-inch mainline run, making it a standard component in residential and commercial sanitary sewer and storm drainage piping. The SDR-35 wall thickness rating ensures the fitting meets the structural requirements for underground sewer applications. Licensed plumbers and pipefitters install this type of fitting during new construction and pipe replacement projects.

This sanitary tee is suited for underground sanitary sewer and storm drainage installations where a swept-inlet branch connection is required. It is commonly used in residential site work, commercial construction, and municipal lateral connections. The solvent weld joint style creates a permanent, leak-resistant bond when used with the appropriate PVC primer and cement per local plumbing code requirements.

Key Features

• SDR-35 wall thickness rated for gravity-flow underground sewer service
• 6-inch mainline by 4-inch branch configuration for reducing lateral connections
• Solvent weld joints for a permanent, code-compliant bond
• PVC construction resists corrosion, root intrusion chemicals, and biological degradation
• Swept inlet design promotes smooth flow and reduces solids buildup at the branch entry

Compatibility

Designed as an OEM-style replacement and new-installation fitting for SDR-35 PVC gravity sewer piping systems using 6-inch mainline and 4-inch branch pipe.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code and applicable local amendments. Shut off or divert flow in the existing line before cutting in the fitting. Clean and dry all mating surfaces, apply approved PVC primer, then solvent cement before joining. Allow full cure time per the cement manufacturer instructions before allowing flow through the fitting.
