The ring measures 2.563 inches inside diameter, 2.75 inches outside diameter, and 0.094 inches thick with a round cross section. Shore A hardness is rated at 75, placing it in the hard durometer range. Operating temperature spans -15 degrees F to 400 degrees F, making it suitable for demanding fluid and gas sealing environments encountered in HVAC, plumbing, refrigeration, and industrial systems. Sold in a package quantity of 10.\u003c\/p\u003e\u003cp\u003eThis O-ring is well suited for use with petroleum-based fluids, hydraulic oils, fuels, and related media. Its fluoroelastomer compound provides low gas permeability, making it appropriate for vacuum service applications. Typical installation scenarios include pump seals, valve stems, fittings, and manifold connections in residential and commercial mechanical systems. The brown color is standard for Viton-compound O-rings and aids in field identification when sorting mixed seal inventories.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFluoroelastomer (Viton) compound offers high resistance to petroleum products and a wide spectrum of chemical compatibility\u003c\/li\u003e\n\u003cli\u003eTemperature range of -15 degrees F to 400 degrees F supports high-heat service environments\u003c\/li\u003e\n\u003cli\u003e75 Shore A hardness rating provides a hard, low-compression-set seal under sustained clamping loads\u003c\/li\u003e\n\u003cli\u003eLow gas permeability makes this ring suitable for vacuum service applications\u003c\/li\u003e\n\u003cli\u003eRound cross section, Dash 145 sizing for straightforward replacement and sourcing\u003c\/li\u003e\n\u003cli\u003ePackage quantity of 10 supports stocking for repeat service calls\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 145 O-ring replacement compatible with grooves and fittings dimensioned for 2.563 inches inside diameter and 0.094 inches cross-section thickness.
