With an inside diameter of 8.5 inches, an outside diameter of 8.875 inches, and a cross-section thickness of 0.1875 inches, this O-ring fits large-bore connections commonly found in HVAC, plumbing, and industrial fluid systems. The round cross-section profile seats cleanly in standard groove cuts. At 70 durometer hardness, it balances flexibility and compression resistance. It is typically installed by licensed plumbers, HVAC technicians, and industrial maintenance professionals.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for sealing applications involving petroleum-based fluids, hydraulic oils, fuels, and similar hydrocarbons. The fluoroelastomer compound maintains a reliable seal across a working temperature range of -15 degrees F to 400 degrees F, making it appropriate for high-temperature fluid systems and vacuum service applications. Its low gas permeability makes it a dependable choice where gas-tight seals are required, including refrigerant circuits and pressurized fluid lines. The Dash 371 designation follows AS568 standard sizing, allowing straightforward cross-referencing to groove specifications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFluoroelastomer (Viton) compound provides strong resistance to petroleum products and a wide spectrum of chemicals\u003c\/li\u003e\n\u003cli\u003eWorking temperature range of -15 degrees F to 400 degrees F suits high-heat and cryogenic-adjacent applications\u003c\/li\u003e\n\u003cli\u003e70 durometer hardness rating delivers low compression set over extended service cycles\u003c\/li\u003e\n\u003cli\u003eRound cross-section conforms to standard AS568 Dash 371 groove geometry\u003c\/li\u003e\n\u003cli\u003eLow gas permeability makes it suitable for vacuum service and pressurized gas containment\u003c\/li\u003e\n\u003cli\u003eSold in a package quantity of 2\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to fit any application calling for an AS568 Dash 371 O-ring with an 8.5-inch inside diameter, 8.875-inch outside diameter, and 0.1875-inch cross-section thickness.
