Royal Building Products 35-1615 8 Inch Sewer Gasket Plug

Product Description

The ROYAL BUILDING PRODUCTS 35-1615 is an 8-inch sewer gasket plug designed to seal and cap sewer drain lines during testing, repair, and maintenance operations. This plug relies on a compression gasket mechanism to form a watertight seal inside the pipe bore, preventing flow or pressure loss during service work. It is suited for use in sanitary drain systems and is typically installed by licensed plumbers and drain technicians working on residential and light commercial sewer lines.

This gasket plug is intended for use in 8-inch sewer drain pipe applications. It is commonly deployed when pressure-testing drain lines, isolating a section of sewer pipe for repair, or temporarily capping an open line during construction or retrofit work. Plumbers use this style of plug on both new installations and existing systems where a secure, removable seal is required without permanent modification to the piping.

Key Features

• 8-inch nominal size fits standard sewer drain pipe bores
• Gasket-style compression seal provides a watertight fit during testing and service
• Removable design allows temporary capping without permanent pipe alteration
• Suitable for sanitary sewer drain line applications in residential and light commercial settings

Compatibility

Designed as an OEM-style replacement and standard fitment for 8-inch nominal sewer drain pipe systems.

Installation Notes

Installation is typically performed by a licensed plumber. Before inserting the plug, confirm the pipe bore is clean and free of debris that could compromise the gasket seal. Isolate the section of pipe and relieve any system pressure before inserting or removing the plug. Follow applicable plumbing codes, including IPC guidelines, for pressure testing and temporary pipe sealing procedures.
