The ASC Engineered Solutions 390080026 is an EPDM gasket sized for 2.5-inch grooved piping systems. It seats inside the Gruvlok 7012 grooved flange coupling to create a leak-tight seal between pipe ends. EPDM rubber provides solid performance across a range of water and mechanical system applications, resisting compression set under repeated thermal cycling. The gasket is identified by its green color coding, consistent with standard EPDM grading in grooved coupling systems. Weighing 0.10 pounds, it is a direct drop-in sealing component requiring no adhesives or special tools to seat. Plumbers and pipefitters working on grooved piping assemblies stock these as standard replacement seals.
This gasket is designed for use with the Gruvlok 7012 grooved flange fitting at the 2.5-inch pipe size. Typical installations include commercial plumbing, fire protection, and mechanical piping systems where grooved-end couplings are specified. The green EPDM material is suited for cold and hot water service lines where a resilient, elastomeric seal is required. It fits into the standard gasket groove of the 7012 flange housing and is installed during initial assembly or as a replacement during routine maintenance of grooved piping connections.
Designed for use with the Gruvlok 7012 Grooved Flange at 2.5-inch pipe size as stated by the manufacturer.
Installation is performed by licensed plumbers or pipefitters working on grooved-end piping assemblies. Depressurize and drain the pipe section before removing any existing coupling or gasket. Inspect the pipe groove and flange housing seating surface for damage before installing the replacement gasket. Follow the coupling manufacturer torque and assembly procedure for the 7012 housing to ensure proper gasket compression and seal integrity.
