It measures 5.75 inches inside diameter, 6 inches outside diameter, and 0.125 inches thick with a round cross section. Rated for service from -15 degrees F to 400 degrees F, this O-ring delivers low compression set and low gas permeability. Each package contains 2 O-rings. The fluoroelastomer compound provides a wide spectrum of chemical compatibility, making it a reliable choice for demanding industrial and mechanical sealing jobs.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for use in HVAC, plumbing, hydraulic, and industrial fluid systems where petroleum-based media, high temperatures, or vacuum service conditions are present. The Dash 256 designation identifies the standard AS568 size, making it straightforward to cross-reference for replacement or MRO applications. It is appropriate for both residential and light commercial equipment as well as general industrial machinery where a large-diameter fluoroelastomer seal is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFluoroelastomer (Viton-type) material offers broad chemical resistance including petroleum products\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of -15 degrees F to 400 degrees F supports high-heat applications\u003c\/li\u003e\n\u003cli\u003eLow compression set maintains sealing force over extended service life\u003c\/li\u003e\n\u003cli\u003eLow gas permeability makes it suitable for vacuum service\u003c\/li\u003e\n\u003cli\u003eRound cross section, Dash 256 AS568 standard size for easy cross-referencing\u003c\/li\u003e\n\u003cli\u003ePackage includes 2 O-rings per order\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 256 fluoroelastomer O-ring compatible with petroleum products and suitable for systems requiring resistance to high temperatures and a wide range of chemicals.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by licensed HVAC technicians, plumbers, or industrial maintenance personnel. Always depressurize and drain the system before replacing seals. Inspect the groove dimensions and surface finish to ensure compatibility with the O-ring cross section before installation. Avoid rolling or twisting the O-ring during installation to prevent cross-sectional distortion that can cause premature seal failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Fluoroelastomer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 256\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 5.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 6 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 A (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\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Media\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\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: ZMSCV70256\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711008899378,"sku":"ZMSCV70256","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7cd48aa4c089c464ed9a8a0c48d1bd35.jpg?v=1788473474","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70256-viton-o-ring-dash-256","provider":"Voomi Supply","version":"1.0","type":"link"}
