Anvil 390080927 Flanged Seal Ring 8 Inch Rubber

Product Description

The ANVIL 390080927 is a flanged rubber seal ring designed for use with 7012 and 7312 grooved pipe couplings. The ring seats between the coupling housing and pipe ends to create a pressure-rated, leak-resistant joint. At 8 inches nominal size, it fits standard grooved pipe in that diameter class. Plumbers and pipefitters install this seal ring during assembly or as a replacement when an existing gasket shows wear, cracking, or compression set. Domestic manufacture meets typical procurement requirements for commercial and industrial piping projects.

This seal ring is suited for grooved piping systems in commercial mechanical, industrial, and institutional applications. It is used wherever a 7012 or 7312 coupling is installed on 8-inch grooved pipe, including hydronic heating and cooling loops, fire protection mains, and general water distribution headers. The flanged profile locks into the coupling housing to prevent gasket blowout under pressure.

Key Features

• 8-inch nominal size matches standard grooved pipe in that diameter class
• Flanged seal ring design prevents blowout and maintains gasket position inside the coupling housing
• Rubber construction provides flexibility and compression under mechanical coupling load
• Compatible with 7012 and 7312 grooved coupling housings as a direct replacement
• Domestic manufacture supports project compliance requirements

Compatibility

Designed as a replacement seal ring for ANVIL 7012 and 7312 grooved pipe couplings in 8-inch nominal pipe size.

Installation Notes

Seal ring installation is performed by licensed pipefitters or plumbers working on grooved mechanical piping systems. Depressurize and drain the line segment before disassembling any grooved coupling. Inspect the pipe ends and coupling housing for corrosion or damage before seating the new ring. Lubricate the seal ring with the coupling manufacturer-approved lubricant only and ensure the flanged lip is fully seated in the housing groove before torquing the coupling bolts.
