Rated at 70 durometer hardness, this O-ring is engineered for demanding sealing applications where high temperature resistance, low compression set, and broad chemical compatibility are required. The fluoroelastomer compound handles continuous service from -15 degrees F up to 400 degrees F, making it suitable for systems that cycle through wide thermal ranges. Licensed plumbers, pipefitters, and industrial maintenance technicians typically install this size in large-bore sealing assemblies.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for use in petroleum product handling systems, hydraulic circuits, vacuum service lines, and process piping where standard Buna-N compounds fall short. The Dash 266 designation follows AS568 sizing standards, making it a direct fit in any application calling out that dash number. Its low gas permeability rating also supports vacuum and pressure containment service. Package quantity is 2 rings per package with a minimum order quantity of 1.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFluoroelastomer (Viton) compound for broad chemical and petroleum product resistance\u003c\/li\u003e\n  \u003cli\u003e70 durometer hardness rating with hard hardness classification for positive compression sealing\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -15 degrees F to 400 degrees F\u003c\/li\u003e\n  \u003cli\u003eLow compression set maintains seal integrity over repeated thermal cycles\u003c\/li\u003e\n  \u003cli\u003eLow gas permeability supports vacuum service applications\u003c\/li\u003e\n  \u003cli\u003eRound cross section, Dash 266 per AS568 sizing standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a Dash 266 AS568-standard O-ring for large-bore sealing assemblies requiring fluoroelastomer compound compatibility with petroleum products and high-temperature process fluids.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers, pipefitters, or industrial maintenance technicians. De-pressurize and drain the system completely before disturbing any seal or fitting. Inspect the O-ring groove for nicks, burrs, or corrosion before seating the new ring, and apply a compatible lubricant to ease installation and prevent rolling. Do not stretch the O-ring over sharp threads or edges, as surface damage compromises the seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Fluoroelastomer (Viton)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 266\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 8 inches (8.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 8.25 inches (8.2500 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 durometer (Hard)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -15 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 400 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Material\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\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: ZMSCV70266\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722392633650,"sku":"ZMSCV70266","price":19.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95af013f1047efd3723d888ef917b41c.jpg?v=1788590446","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70266-viton-o-ring-dash-266","provider":"Voomi Supply","version":"1.0","type":"link"}
