It features a round cross section measuring 0.301 inches inside diameter, 0.429 inches outside diameter, and 0.064 inches thick. Rated for service from -15 degrees F to 400 degrees F, this O-ring delivers low compression set and high temperature resistance. Its fluoroelastomer compound provides wide chemical compatibility and low gas permeability, making it suitable for vacuum service applications. Each package contains 25 O-rings. Licensed HVAC techs, plumbers, and pipefitters are the typical installers.\u003c\/p\u003e\u003cp\u003eThis O-ring functions as a boss gasket for straight-thread tube fittings, commonly used in hydraulic, pneumatic, fuel, and refrigerant line connections where resistance to petroleum products is required. Its black fluoroelastomer construction suits residential and commercial installations wherever elevated temperatures or aggressive fluid contact rule out standard NBR or EPDM compounds. The Dash 903 designation follows standard O-ring sizing and allows direct cross-referencing with most industry sizing charts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFluoroelastomer (Viton) material for superior heat and chemical resistance\u003c\/li\u003e\n\u003cli\u003eRated from -15 degrees F to 400 degrees F continuous service temperature\u003c\/li\u003e\n\u003cli\u003eRound cross section; functions as O-ring boss gasket for straight-thread tube fittings\u003c\/li\u003e\n\u003cli\u003eLow compression set and low gas permeability — suitable for vacuum service\u003c\/li\u003e\n\u003cli\u003eGood resistance to petroleum products and a wide spectrum of chemical compatibility\u003c\/li\u003e\n\u003cli\u003eSold in a package of 25 pieces (minimum order quantity: 1 package)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Dash 903 O-ring boss gasket for straight-thread tube fittings in systems handling petroleum products, hydraulic fluids, fuels, and refrigerants where fluoroelastomer sealing material is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers, HVAC technicians, or pipefitters.
