It measures 0.644 inches inside diameter, 0.818 inches outside diameter, and 0.087 inches thick with a round cross section. The material is a 70-durometer fluoroelastomer rated for service from -15 degrees F to 400 degrees F, making it suitable for high-temperature and chemical-exposure environments. Each package contains 25 O-rings. Licensed plumbers, pipefitters, and hydraulic technicians working with petroleum-based fluids and high-temperature systems will find this seal appropriate for demanding service conditions.\u003c\/p\u003e\u003cp\u003eThis O-ring is used as a boss gasket for straight-thread tube fittings in hydraulic, pneumatic, and fluid-transfer systems where petroleum product compatibility and high-temperature resistance are required. The fluoroelastomer compound provides good chemical resistance across a wide spectrum of fluids and offers low gas permeability, making it suitable for vacuum service as well. Typical install environments include industrial fluid systems, HVAC refrigerant-adjacent plumbing, and mechanical equipment with threaded port connections exposed to elevated temperatures or aggressive fluid media.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFluoroelastomer (Viton-type) material rated from -15 degrees F to 400 degrees F\u003c\/li\u003e\n\u003cli\u003e70-durometer hardness rated Hard for reliable compression sealing under pressure\u003c\/li\u003e\n\u003cli\u003eLow compression set for sustained sealing performance over time\u003c\/li\u003e\n\u003cli\u003eGood resistance to petroleum products and a wide spectrum of chemical media\u003c\/li\u003e\n\u003cli\u003eSuitable for vacuum service with low gas permeability\u003c\/li\u003e\n\u003cli\u003eRound cross section, Dash 908 sizing for straight-thread boss fittings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement boss gasket for straight-thread tube fittings requiring a Dash 908 O-ring in systems handling petroleum products or high-temperature fluids.
