Westlake Pipe Fittings P158-6 Pvc Sanitary Tee 8x6 in SDR-35

Product Description

The WESTLAKE PIPE FITTINGS P158-6 is an 8 x 6 inch SDR-35 PVC sanitary tee designed for solvent weld installation in gravity-flow drain, waste, and vent (DWV) systems. The sanitary tee configuration allows a branch line to tie into a main run while directing flow smoothly in the direction of drainage. Constructed from SDR-35 PVC, this fitting meets the wall-thickness standard required for sewer and drain service. Licensed plumbers and pipefitters specify this fitting where an 8-inch main line accepts a 6-inch branch connection. At 10.01 pounds, this is a substantial fitting suited for larger commercial and municipal-scale drainage work.

This sanitary tee is used in residential and commercial below-grade or above-grade DWV piping where a reducing branch connection is needed on larger-diameter sewer lines. Typical applications include main building sewer runs, site utility drainage, and storm or sanitary collection systems where an 8-inch trunk line must accept a 6-inch lateral. The solvent weld ends provide a permanent, leak-resistant joint when properly primed and cemented per manufacturer and code requirements.

Key Features

• SDR-35 PVC construction rated for gravity sewer and drain service
• 8-inch main run with 6-inch reducing branch outlet
• Solvent weld ends for a permanent, code-compliant bonded joint
• Sanitary sweep interior promotes smooth, unobstructed flow toward the main run
• Heavyweight build at 10.01 pounds suited for larger-diameter commercial installations

Compatibility

Designed as an OEM-style replacement and new-construction fitting for 8-inch SDR-35 PVC gravity sewer and DWV piping systems requiring a 6-inch solvent weld branch connection.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local code. Shut off flow and isolate the line segment before cutting into an existing system. Use the correct PVC primer and solvent cement rated for SDR-35 pipe and fittings, and allow full cure time before restoring flow. Confirm branch orientation for proper drainage direction before making permanent joints, as solvent weld connections cannot be disassembled after cure.
