The ring measures 10 inches inside diameter, 10.25 inches outside diameter, and 0.125 inches in cross-section thickness with a round cross-section profile. Rated at 90 durometer (extra hard), it delivers firm compression set resistance and reliable sealing under pressure. The operating temperature range runs from -40 degrees F to 250 degrees F, making it suitable for a broad range of service environments. Licensed plumbers, pipefitters, and industrial maintenance technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for use in hydraulic systems, pneumatic assemblies, pumps, valves, and pipe fittings that handle petroleum-based fluids and lubricants. The Buna-N compound provides excellent resistance to petroleum products, oils, and fuels, making it a standard choice in HVAC, plumbing, and industrial fluid-system maintenance. It is not recommended for use in ozone-rich environments or in direct prolonged sunlight exposure. The package quantity is 10 rings per pack with a minimum order quantity of 1 pack.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) compound — the most widely used O-ring elastomer for petroleum service\u003c\/li\u003e\n  \u003cli\u003e90 durometer extra-hard rating provides strong compression set resistance and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003eOperating range of -40 degrees F to 250 degrees F covers most commercial and industrial service conditions\u003c\/li\u003e\n  \u003cli\u003eRound cross-section, Dash 274 designation for straightforward replacement identification\u003c\/li\u003e\n  \u003cli\u003eCompatible with petroleum products, oils, and hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with systems and assemblies that handle petroleum products and oils.

Depressurize and isolate the system fully before removing the existing O-ring or introducing the replacement. Avoid rolling or twisting the O-ring during installation, as this can cause premature seal failure. Do not store O-rings near motors, electrical equipment, or in direct sunlight, as ozone and UV exposure degrade Buna-N compound over time.\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: 274\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 10 inches (253.59 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 10.25 inches (260.35 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 Fluids\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 per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.05 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: ZMSCH90274\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693185106226,"sku":"ZMSCH90274","price":24.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e63e5be40384736fb1f090e4d0cdd585_5dca633b-4656-45a7-adfb-c39fcca96fa2.jpg?v=1788308582","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch90274-o-ring-dash-274-buna-n","provider":"Voomi Supply","version":"1.0","type":"link"}
