Westlake Pipe Fittings g1212-8 Sdr 35 Pvc Sewer Bushing 12x8 in

Product Description

The WESTLAKE PIPE FITTINGS g1212-8 is a 12-inch by 8-inch SDR 35 PVC segmental sewer bushing with a gasketed small end. This fitting reduces a 12-inch sewer main to an 8-inch pipe connection while maintaining the SDR 35 wall dimension standard required for gravity sewer applications. Constructed from PVC, it is lightweight relative to concrete or clay alternatives and resistant to corrosion and chemical degradation common in municipal and commercial sewer environments. Plumbers and underground utility contractors install this fitting where inline reductions are needed in gravity-flow sewer lines.

This bushing is used in residential, commercial, and light municipal gravity sewer systems built to SDR 35 specifications. Typical applications include main-to-lateral transitions and in-line diameter reductions in buried drain lines. The gasketed small end allows for a secure, flexible joint that accommodates minor pipe movement and differential settlement without relying on solvent cement at that connection point. It is suited for direct-bury installations in trenched sewer construction projects.

Key Features

• SDR 35 wall rating meets standard requirements for gravity sewer service
• Gasketed small end provides a flexible, pressure-assisted seal without solvent welding
• PVC construction resists corrosion, root intrusion degradation, and common sewer gases
• Reduces 12-inch mainline to 8-inch lateral or branch connection in a single fitting
• At 11.5 pounds, manageable for single-person handling in trench conditions

Compatibility

Designed as an OEM-style replacement and new-installation fitting for SDR 35 PVC gravity sewer piping systems with a 12-inch mainline and an 8-inch branch or lateral pipe.

Installation Notes

Installation is performed by licensed plumbers or underground utility contractors following applicable plumbing codes such as the IPC or local sewer authority specifications. Ensure the trench is properly bedded and that pipe ends are clean and deburred before seating the gasket joint. Do not use solvent cement on the gasketed end. Inspect the gasket for nicks or displacement before making the final connection, and verify alignment before backfilling.
