It measures 0.755 inches inner diameter by 0.949 inches outer diameter with a cross-section thickness of 0.097 inches. The round cross-section profile seats reliably in standard O-ring grooves. At 90 Shore A hardness (Extra Hard rating), this O-ring delivers strong resistance to compression set, tearing, and abrasion. Buna-N is the most widely used O-ring elastomer in trade applications, particularly where petroleum-based media are present.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for residential and commercial applications involving petroleum-based fluids and hydraulic systems. HVAC technicians, plumbers, and mechanical contractors use Dash 910 O-rings as replacement seals in valves, fittings, pumps, and refrigerant-side components compatible with petroleum products. The operating temperature range spans -40 degrees F to 250 degrees F, making it appropriate for a wide range of service environments. Each order contains 100 pieces, supporting both single-repair and bulk maintenance needs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBuna-N (Nitrile Butadiene Rubber) construction  -  excellent resistance to petroleum products and hydraulic fluids\u003c\/li\u003e\n\u003cli\u003e90 Shore A hardness (Extra Hard) for strong compression set resistance and dimensional stability under load\u003c\/li\u003e\n\u003cli\u003eRound cross-section profile for reliable seating in standard Dash 910 O-ring grooves\u003c\/li\u003e\n\u003cli\u003eOperating range of -40 degrees F to 250 degrees F suits a broad range of mechanical and HVAC service conditions\u003c\/li\u003e\n\u003cli\u003eTear and abrasion resistant for demanding sealing environments\u003c\/li\u003e\n\u003cli\u003eSold in a 100-piece package  -  suitable for fleet service and bulk repair stock\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with petroleum products and petroleum-based hydraulic fluids. Designed as a standard Dash 910 O-ring replacement for valves, fittings, and mechanical assemblies requiring a 0.755-inch ID Buna-N seal. Not recommended for applications involving ozone exposure, direct sunlight storage, or proximity to motors and other ozone-generating electrical equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic, plumber, or HVAC technician. Always depressurize and de-energize the system before replacing O-rings; relieve all fluid or refrigerant pressure and confirm the line is isolated before disassembly. Lubricate the O-ring with a compatible fluid during installation to prevent tearing during seating. Do not store unused O-rings in direct sunlight or near motors or other electrical equipment that may generate ozone, as ozone exposure degrades Buna-N material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Buna-N (Nitrile Butadiene Rubber)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 910\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.7550 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.9490 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness (Cross Section)\u003c\/strong\u003e: 0.0970 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 90 Shore A (Extra Hard)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Media\u003c\/strong\u003e: Petroleum Products\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31401503\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: USA INDUSTRIALS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ZUSAH90910\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"USA INDUSTRIALS","offers":[{"title":"Default Title","offer_id":51972122607922,"sku":"ZUSAH90910","price":27.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8eeb1d85faeec493547bdef75c5b6195.jpg?v=1789963028","url":"https:\/\/voomisupply.com\/products\/usa-industrials-zusah90910-o-ring-dash-910-buna-n-100pc","provider":"Voomi Supply","version":"1.0","type":"link"}
