This round cross-section ring measures 2.563 inches inside diameter, 2.75 inches outside diameter, and 0.0937 inches thick. With a Shore A hardness of 70 and a working temperature range of -40 degrees F to 250 degrees F, it delivers reliable compression set resistance, tear resistance, and abrasion resistance. Sold in packs of 50, this O-ring is a standard choice for plumbing, hydraulic, pneumatic, and fluid-handling maintenance work.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for use with petroleum-based fluids and oils, making it a fit for hydraulic systems, fuel systems, pumps, valves, and compressors commonly found in HVAC, plumbing, and industrial equipment. It conforms to SAE and MIL-Spec standards, which makes it appropriate for both commercial and light industrial service environments. Plumbers, HVAC technicians, and equipment mechanics regularly stock Buna-N O-rings at this size for routine seal replacements and preventive maintenance. The pack quantity of 50 supports service fleets and shop inventory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) construction with excellent resistance to petroleum products\u003c\/li\u003e\n  \u003cli\u003eDash 145 standard sizing: 2.563 inches ID, 2.75 inches OD, 0.0937 inches thick\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range from -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eShore A hardness of 70 for reliable compression set and sealing performance\u003c\/li\u003e\n  \u003cli\u003eRound cross-section profile for standard groove fitment\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards; sold in a 50-piece pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement O-ring for any application requiring a Dash 145 size in Buna-N material.
