It measures 17 inches inside diameter, 17.25 inches outside diameter, and 0.125 inches thick, with a round cross section and a Shore hardness rating of 70. This O-ring is suited for static and dynamic sealing in systems that handle petroleum-based fluids. It ships in a package quantity of two and is installed by plumbers, pipefitters, HVAC technicians, and industrial maintenance trades wherever a standard Dash 283 seal is required.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is commonly used in large-diameter pipe flanges, pump housings, valve bonnets, and fluid system assemblies that contact petroleum products, oils, and hydraulic fluids. Its Buna-N compound provides excellent resistance to petroleum-based media, making it a practical choice in plumbing, HVAC, and light industrial equipment where sealing integrity against oils and fuels is a service priority. It is not recommended for use with ozone-generating equipment or in direct sunlight storage conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) compound with excellent resistance to petroleum products, oils, and hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003eShore hardness of 70 with a hard hardness rating for reliable compression set performance\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eRound cross section profile for consistent seating in standard O-ring grooves\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003eBlack color; package quantity of 2 per order\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 283 O-ring replacement compatible with petroleum products and systems requiring Buna-N elastomer seals in large-diameter applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers, pipefitters, or HVAC technicians as part of routine maintenance or component replacement. Depressurize and drain the system fully before removing any existing seals. Clean the O-ring groove and mating surfaces to remove debris or old seal material before seating the new O-ring. Do not store Buna-N O-rings near motors, electrical equipment, or in direct sunlight, as ozone and UV exposure degrade the elastomer.\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: 283\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 17 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 17.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 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: 70 Shore\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: 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: 2\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: ZMSCH70283\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718149013810,"sku":"ZMSCH70283","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_4339209c-eb71-4f1d-ada8-7abcb0e3d0e8.jpg?v=1788550356","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70283-o-ring-dash-283-nitrile-nbr","provider":"Voomi Supply","version":"1.0","type":"link"}
