Measuring 4.75 inches inside diameter, 5 inches outside diameter, and 0.125 inches thick with a round cross section, this O-ring carries a Shore A hardness rating of 70 and is rated for service from -15 degrees F to 400 degrees F. It is sold in a pack of five and is suitable for installation by licensed plumbers, HVAC technicians, industrial maintenance mechanics, and experienced trade professionals working with fluid or gas sealing systems.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for applications involving petroleum-based fluids and oils, hydraulic systems, fuel handling lines, and high-temperature sealing environments. The fluoroelastomer compound provides low compression set and low gas permeability, making it a reliable choice for vacuum service and pressurized sealing joints in both residential and light commercial mechanical systems. It is not FDA approved and should not be specified for food-contact or potable-water applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFluoroelastomer (Viton) compound rated from -15 degrees F to 400 degrees F\u003c\/li\u003e\n  \u003cli\u003eShore A hardness of 70 for reliable compression and sealing force under load\u003c\/li\u003e\n  \u003cli\u003eRound cross section with 0.125-inch thickness for standard groove fitment\u003c\/li\u003e\n  \u003cli\u003eLow compression set helps maintain seal integrity over extended service life\u003c\/li\u003e\n  \u003cli\u003eLow gas permeability suitable for vacuum service applications\u003c\/li\u003e\n  \u003cli\u003eCompatible with petroleum products and a wide spectrum of chemical environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 248 O-ring replacement for sealing grooves requiring a 4.75-inch inside diameter, 5-inch outside diameter, and 0.125-inch cross section thickness.
