Asc 390080869 Gruvlok Seal Ring 4 in 7012 7312 Flange

Product Description

The ASC Engineered Solutions 390080869 is a Gruvlok seal ring designed for use with 7012 and 7312 series grooved pipe flanges in 4-inch pipe applications. This elastomeric sealing component seats between the flange face and the mating surface, providing a pressure-rated seal at grooved piping connections. It is a direct-fit replacement element for the specified flange series and is installed by licensed plumbers, pipefitters, and mechanical contractors working on grooved piping systems in commercial and industrial settings.

This seal ring is sized for 4-inch grooved pipe and is intended for use specifically with Gruvlok 7012 and 7312 flange couplings. These flange types are common in mechanical piping systems including HVAC hydronic loops, chilled water distribution, fire protection headers, and industrial process piping where grooved-end flange connections are specified. The seal ring maintains joint integrity at the flange interface and must be replaced any time the flange joint is broken and re-made during service or system modification.
