The ASC ENGINEERED SOLUTIONS 390080034 is a 3-inch EPDM gasket designed for use with the Gruvlok 7012 Grooved Flange. EPDM rubber provides reliable sealing performance across a wide range of fluid and temperature applications commonly found in commercial and industrial piping systems. At 0.10 pounds, this lightweight gasket seats into the grooved flange face to create a pressure-rated seal when the flange is bolted together. Plumbers, pipefitters, and mechanical contractors working with grooved piping assemblies will find this gasket a direct-fit component for completing 7012 flange connections.
This gasket is used in grooved-end piping systems where a 3-inch flanged transition is required. The 7012 Grooved Flange is a common fitting in HVAC hydronic systems, fire protection, and general commercial plumbing. The gasket installs between mating flange faces, providing a fluid-tight seal once fasteners are torqued down. It is appropriate for both new construction and retrofit service work on grooved mechanical piping assemblies.
Designed for use with the Gruvlok 7012 Grooved Flange in 3-inch grooved piping configurations.
Installation should be performed by a licensed plumber or pipefitter familiar with grooved mechanical piping systems. Shut off and depressurize the piping system completely before replacing or installing any flange gasket. Ensure the flange seating faces are clean and free of debris before placing the gasket. Follow the flange bolt torque sequence recommended in the system manufacturer documentation and applicable mechanical codes.
