It measures 1.375 inches inside diameter, 1.5 inches outside diameter, and 0.0625 inches thick with a round cross-section. The compound carries a Shore A hardness of 75, placing it in the hard hardness rating category. Rated for service from -15 degrees F to 400 degrees F, this O-ring suits high-temperature fluid and gas sealing applications where petroleum-based media, wide-spectrum chemical exposure, or vacuum service is a concern. Fluoroelastomer construction provides low compression set and low gas permeability.\u003c\/p\u003e\u003cp\u003eThis O-ring is used in HVAC, plumbing, hydraulic, pneumatic, and industrial equipment where a reliable static or dynamic face seal or radial seal is required. The Dash 028 sizing is a standard AS568 designation, making it a direct fit in any groove machined to that standard. Its resistance to petroleum products and high-temperature stability make it well suited for fuel systems, refrigerant service valves, pump seals, and process fittings across residential and light commercial applications. The 50-piece pack supports shop stock or service van inventory.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFluoroelastomer (Viton) material with good resistance to petroleum products and a wide spectrum of chemicals\u003c\/li\u003e\n\u003cli\u003eTemperature range of -15 degrees F to 400 degrees F for high-heat service environments\u003c\/li\u003e\n\u003cli\u003eShore A hardness of 75 for a firm, low-compression-set seal\u003c\/li\u003e\n\u003cli\u003eLow gas permeability and suitable for vacuum service\u003c\/li\u003e\n\u003cli\u003eStandard AS568 Dash 028 sizing fits any groove machined to that designation\u003c\/li\u003e\n\u003cli\u003ePack of 50 supports bulk stocking and repeat-service use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AS568 Dash 028 O-ring replacement compatible with petroleum products and equipment requiring fluoroelastomer sealing material.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by licensed HVAC technicians, plumbers, or industrial mechanics depending on the application. Always depressurize and de-energize the system before replacing any O-ring seal. Inspect the mating groove for nicks, burrs, or corrosion before installing the new ring. Use only lubricants compatible with fluoroelastomer compounds; avoid silicone greases where petroleum-based media is present, and do not twist or roll the O-ring during installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 028\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.375 inches (34.65 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.5 inches (38.21 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0625 inches (1.78 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShore A Hardness\u003c\/strong\u003e: 75 (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: Brown\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: 50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 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: ZMSCVB75028\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722817863986,"sku":"ZMSCVB75028","price":25.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f0e36f9f99629f739efd82c3e8c67be_65b462cd-1fbe-4188-8156-c1c24eef9f80.jpg?v=1788596363","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscvb75028-viton-o-ring-dash-028-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
