It measures 10.5 inches inside diameter, 10.75 inches outside diameter, and 0.125 inches thick. Rated at 70 Shore hardness, it handles temperatures from -40 degrees F to 250 degrees F and is compatible with petroleum-based media. Buna-N is the most widely used O-ring elastomer in trade applications, offering strong resistance to petroleum products, good compression set performance, and solid tear and abrasion resistance. Licensed plumbers, pipefitters, and fluid-system technicians reach for this material as a standard sealing solution across a wide range of industrial and mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for use in hydraulic systems, pneumatic assemblies, fuel and oil lines, and general plumbing connections where petroleum-fluid compatibility is required. The Dash 275 designation follows standard AS568 sizing, making it straightforward to cross-reference against existing system documentation. It is appropriate for both residential and light commercial service applications where a reliable, large-diameter face seal or static seal is needed. The pack quantity of 5 supports field technicians who require spares on hand for recurring maintenance tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) material with excellent resistance to petroleum products\u003c\/li\u003e\n  \u003cli\u003eDash 275 standard sizing: 10.5 inches ID, 10.75 inches OD, 0.125 inches thick\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e70 Shore hardness (Hard rating) for reliable compression sealing\u003c\/li\u003e\n  \u003cli\u003eRound cross section for consistent seating in standard O-ring grooves\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003eSold in a pack of 5 to support ongoing service needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum-based fluids and products.

Always depressurize and drain the system before replacing an O-ring to prevent injury and ensure a proper seal. Inspect the groove and mating surfaces for nicks, burrs, or contamination before seating the new ring. Avoid storing Buna-N O-rings near electric motors, ozone-generating equipment, or in direct sunlight, as ozone and UV exposure degrade nitrile rubber over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nitrile Butadiene Rubber (Buna-N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 10.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 10.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 275\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: 70 Shore (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\u003eStandards\u003c\/strong\u003e: SAE, MIL-Spec\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31401503\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: ZMSCH70275\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715618079026,"sku":"ZMSCH70275","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5882ead709679393d90bacb710e8f49c.jpg?v=1788516402","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70275-o-ring-dash-275-nitrile-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
