The WESTLAKE PIPE FITTINGS g308 is an 8-inch SDR 35 PVC gasketed sewer wye fitting designed for gravity-flow sewer and drain systems. It accepts a gasketed connection on all openings, allowing for a watertight, push-fit assembly without solvent cement. The wye configuration diverts flow at a 45-degree lateral angle, making it a standard choice for mainline branch connections in underground sewer installations. At 13 pounds, this is a substantial fitting suited for larger-diameter sewer work. Licensed plumbers and sewer contractors install this type of fitting in residential and commercial gravity drain systems.
This fitting is used in underground sewer and storm drain installations where 8-inch SDR 35 PVC pipe is the mainline material. SDR 35 is the most common specification for municipal and site sewer work, conforming to pressure-class requirements for gravity sewer service. Typical applications include main sewer line branch connections at building services, lateral tie-ins, and contractor-grade residential sewer stub-outs. The gasketed connection type makes it compatible with standard gasketed SDR 35 pipe ends commonly used on job sites.
Designed as an OEM-style replacement and standard fitting for 8-inch SDR 35 gasketed PVC sewer pipe systems used in gravity-flow underground drain and sewer applications.
Installation of this fitting is typically performed by licensed plumbers or sewer contractors in accordance with local plumbing codes and the International Plumbing Code (IPC). The trench and pipe bedding must be prepared to proper grade before setting the fitting to maintain gravity flow. Ensure all gaskets are properly seated and pipe ends are clean and lubricated before pushing connections together. Do not use solvent cement on gasketed SDR 35 joints.
