Royal Building Products 35-1801 Gasket Tee 6x4 Inch

Product Description

The ROYAL BUILDING PRODUCTS 35-1801 is a 6-inch by 4-inch gasket-seal tee fitting designed for sewer and drain piping systems. This tee provides a branch connection in solid-wall drainage pipe runs, using a compression gasket joint for a secure, leak-resistant seal without solvent cement. It is typically installed by licensed plumbers during new construction or repair work on residential and light commercial gravity-drain systems. The gasket-style connection allows for faster assembly and field adjustment compared to solvent-welded fittings, making it a practical choice for underground or in-wall drain configurations.

This fitting is suited for sewer and drain applications where a 4-inch branch outlet is required off a 6-inch main line. It is commonly used in residential and light commercial plumbing systems for connecting lavatory, sink, or floor drain branch lines into a larger main drain stack or horizontal run. The compression gasket design is appropriate for below-grade and in-slab installations where a reliable, watertight connection is required.

Key Features

• 6-inch by 4-inch tee configuration provides a reduction branch off the main line
• Compression gasket joint design eliminates the need for solvent cement at connection points
• Compatible with solid-wall sewer and drain pipe in standard OD dimensions
• Suitable for below-grade and underground drain installations
• Gasket seal accommodates minor field alignment adjustments during installation

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 6-inch by 4-inch sewer and drain piping systems using gasket-joint solid-wall pipe.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off flow and isolate the affected drain section before cutting into an existing line. Ensure pipe ends are clean, deburred, and properly lubricated before seating the gasket joint. Do not over-deflect the joint beyond the fitting manufacturer's stated angular tolerance.
