It measures 9.25 inches inside diameter, 9.5 inches outside diameter, and 0.125 inches thick with a round cross section. Rated at 90 durometer (extra hard), it delivers firm compression set resistance along with strong tear and abrasion resistance. The operating temperature range runs from -40 degrees F to 250 degrees F, making it suitable for demanding industrial and mechanical environments. Licensed tradespeople and maintenance technicians handling petroleum-based fluid systems will find this O-ring a reliable sealing component.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is intended for use in applications involving petroleum products, hydraulic fluids, oils, and fuels where a Buna-N compound is the specified material. The Dash 271 size designation follows standard O-ring sizing conventions, and the 90 durometer hardness rating suits high-pressure or high-extrusion-risk installations. Typical applications include pump housings, valve bodies, cylinder heads, and pipe flanges in industrial, HVAC, plumbing, and fluid-power systems. Compliance with SAE and MIL-Spec standards makes this part appropriate for both commercial and light military-spec maintenance work. Parts are sold in packages of 10.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (nitrile butadiene rubber) compound offers excellent resistance to petroleum products, hydraulic oils, and fuels\u003c\/li\u003e\n  \u003cli\u003e90 durometer extra-hard rating provides strong resistance to extrusion and compression set\u003c\/li\u003e\n  \u003cli\u003eOperating range of -40 degrees F to 250 degrees F suits a wide range of service conditions\u003c\/li\u003e\n  \u003cli\u003eRound cross section, 0.125 inches thick, conforms to standard Dash 271 sizing\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003eSold in a package quantity of 10\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum products, hydraulic oils, fuels, and similar petroleum-based media.

Always depressurize and drain the system before removing any sealing components. Inspect the O-ring groove and mating surfaces for nicks, burrs, or corrosion before installing a new O-ring. Avoid twisting or rolling the O-ring during installation, and do not store unused O-rings in direct sunlight or near ozone-generating equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 271\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 9.25 inches (234.54 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 9.5 inches (241.30 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 inches (3.53 mm)\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 Durometer (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\u003eStandards\u003c\/strong\u003e: SAE, MIL-Spec\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.95 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ZMSCH90271\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689108865330,"sku":"ZMSCH90271","price":22.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e63e5be40384736fb1f090e4d0cdd585_3be7659f-adf9-423c-b8e0-58ee10509ac9.jpg?v=1788254829","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch90271-o-ring-dash-271-nitrile","provider":"Voomi Supply","version":"1.0","type":"link"}
