It measures 5.5 inches inside diameter, 5.875 inches outside diameter, and 0.1875 inches thick. The fluoroelastomer compound delivers a 70 Shore A hardness rating, suitable for high-temperature environments up to 400 degrees F and cold-weather service down to -15 degrees F. This part is installed by licensed HVAC technicians, plumbers, and industrial maintenance professionals requiring dependable seals in petroleum-based fluid systems.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for residential and commercial applications where exposure to petroleum products, fuels, oils, and hydraulic fluids is expected. Its wide chemical compatibility and low gas permeability make it appropriate for vacuum service lines and high-temperature sealing points in refrigeration, fuel delivery, and hydraulic circuit assemblies. The Dash 357 designation follows AS568 standard sizing, making it a straightforward dimensional match for equipment calling out that dash number. Each package contains 2 O-rings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFluoroelastomer (Viton) compound rated from -15 degrees F to 400 degrees F operating range\u003c\/li\u003e\n\u003cli\u003e70 Shore A hardness for low compression set and durable sealing under sustained load\u003c\/li\u003e\n\u003cli\u003eGood resistance to petroleum products, fuels, and oils\u003c\/li\u003e\n\u003cli\u003eLow gas permeability suitable for vacuum service applications\u003c\/li\u003e\n\u003cli\u003eWide spectrum of chemical compatibility for diverse fluid system environments\u003c\/li\u003e\n\u003cli\u003eRound cross section; Dash 357 AS568 standard sizing for direct dimensional replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with petroleum products and petroleum-based fluid systems.
