It measures 5.25 inches inside diameter, 5.375 inches outside diameter, and 0.0625 inches thick. The compound is rated at 70 Shore A hardness and carries an operating temperature range of -40 degrees F to 250 degrees F. Licensed plumbers, pipefitters, and hydraulic technicians install this style of o-ring when servicing valves, pumps, flanges, and couplings that contact petroleum-based fluids or lubricants.\u003c\/p\u003e\u003cp\u003eThis o-ring is suited for residential and commercial fluid systems where petroleum product compatibility is required. Typical install scenarios include pump seal replacement, valve bonnet sealing, and hydraulic cylinder service. The Buna-N compound is the most widely used elastomer in industrial and trade sealing applications and performs reliably in environments involving oils, fuels, and petroleum-based hydraulic fluids. It is sold in packages of 10 units, making it practical for service trucks and shop stock.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBuna-N (NBR) compound offers excellent resistance to petroleum products, oils, and fuels\u003c\/li\u003e\n\u003cli\u003e70 Shore A hardness rating provides reliable compression set and long service life\u003c\/li\u003e\n\u003cli\u003eOperating range of -40 degrees F to 250 degrees F suits most HVAC, plumbing, and hydraulic environments\u003c\/li\u003e\n\u003cli\u003eRound cross section for consistent sealing in standard o-ring grooves\u003c\/li\u003e\n\u003cli\u003eTear and abrasion resistance supports both static and dynamic sealing applications\u003c\/li\u003e\n\u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with petroleum products, oils, and petroleum-based hydraulic fluids.
