With a 9.5-inch inside diameter, 9.75-inch outside diameter, and 0.125-inch cross-section thickness, this round-profile ring delivers a reliable static or dynamic seal where heat resistance and chemical compatibility are priorities. The fluoroelastomer compound supports continuous service from -15 degrees F up to 400 degrees F, making it suitable for high-temperature environments that would degrade standard Buna-N or EPDM seals. A Shore hardness rating of 70 (Hard) provides controlled compression without excessive deformation under load. Sold in a package of two rings.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for use in petroleum-fluid systems, refrigeration equipment, hydraulic circuits, and vacuum service assemblies. The Dash 272 designation follows the AS568 standard sizing convention, which allows straightforward cross-referencing when replacing worn or damaged seals in large-bore fittings, manifolds, pump housings, or valve bodies. Plumbers, HVAC technicians, and industrial maintenance professionals install this size in applications where larger-diameter sealing surfaces require a chemically resistant fluoroelastomer compound rather than a general-purpose elastomer.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFluoroelastomer (Viton-type) material rated for service up to 400 degrees F\u003c\/li\u003e\n\u003cli\u003eLow compression set characteristics help maintain sealing force over extended service intervals\u003c\/li\u003e\n\u003cli\u003eGood resistance to petroleum products, hydraulic fluids, and a wide spectrum of chemicals\u003c\/li\u003e\n\u003cli\u003eLow gas permeability makes this ring suitable for vacuum service applications\u003c\/li\u003e\n\u003cli\u003eRound cross-section profile conforms to AS568 Dash 272 standard dimensions\u003c\/li\u003e\n\u003cli\u003eShore hardness 70 (Hard) for controlled deformation under compression load\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for large-bore fluoroelastomer O-ring applications requiring AS568 Dash 272 dimensions and compatibility with petroleum products and high-temperature service conditions.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eShut down and depressurize the system completely before removing the old O-ring. Inspect the groove and sealing surfaces for scoring or corrosion before installing the new ring. Apply a thin film of a compatible lubricant — one rated for use with fluoroelastomer compounds and the process fluid — to ease installation and reduce the risk of twisting or cutting the ring during assembly. Fluoroelastomer O-ring service in refrigeration, gas, or plumbing systems must comply with applicable local mechanical codes and manufacturer specifications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 9.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 9.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness (Cross Section)\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 272\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Fluoroelastomer (Viton-type)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\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: -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 Fluids\u003c\/strong\u003e: Petroleum products\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: ZMSCV70272\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721920577842,"sku":"ZMSCV70272","price":20.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd6f83455c531e3c223cd06beda7ea7b.jpg?v=1788583199","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70272-viton-o-ring-dash-272","provider":"Voomi Supply","version":"1.0","type":"link"}
