Royal Building Products 35-181 Sewer Gasket Bushing

Product Description

The ROYAL BUILDING PRODUCTS 35-181 is a sewer gasket bushing designed to create a sealed transition between sewer pipe sections of differing diameters. This type of fitting is used in drain, waste, and vent (DWV) systems to maintain a watertight connection at pipe joints. Based on the part reference data, this bushing is sized for an 8 x 4 inch application. Licensed plumbers and drainage contractors install this component as part of gravity-fed sewer and waste piping assemblies in both residential and light commercial construction.

This gasket bushing is suited for use in underground or below-grade sewer installations where a flexible, compression-style seal is needed between pipes of different nominal diameters. It is appropriate for use in new construction and in repair or replacement work on existing DWV systems. The internal reference codes SEW-GSKBUSH8X4 and G1219 may be used to cross-reference this part with distributor or supplier catalogs.

Key Features

• Designed for 8 x 4 inch pipe diameter transition in DWV sewer applications

Compatibility

Designed as an OEM-style replacement or new-installation fitting for sewer and DWV piping systems requiring an 8 x 4 inch diameter reduction with a gasketed seal. No specific compatible model numbers were provided in the product data.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC) where applicable. Shut off flow and verify the line is clear before beginning any joint work. Ensure mating pipe ends are clean, deburred, and properly aligned before seating the gasket bushing. Do not overtighten mechanical compression fittings, as this can deform the gasket and compromise the seal.
