It measures 0.313 inches inside diameter, 0.563 inches outside diameter, and 0.125 inches thick with a round cross section. Rated at 70 Shore A hardness, this O-ring handles operating temperatures from -15 degrees F to 400 degrees F, making it well suited for high-heat and chemically aggressive service environments. It delivers low compression set, good vacuum service performance, and low gas permeability. HVAC technicians, plumbers, and industrial mechanics use this O-ring for fluid and gas sealing applications where petroleum product exposure is expected.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is appropriate for residential and commercial service applications involving petroleum-based fluids, hydraulic media, and similar chemical environments. Its wide spectrum of chemical compatibility makes it a practical choice for refrigeration fittings, fuel system connections, and hydraulic couplings. The fluoroelastomer compound maintains sealing integrity at elevated temperatures where standard Buna-N or EPDM compounds would degrade. Each package contains 25 O-rings, supporting service kits, bulk repairs, or fleet maintenance stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFluoroelastomer (Viton) compound rated for -15 degrees F to 400 degrees F continuous service\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness for firm sealing under compression in high-pressure fittings\u003c\/li\u003e\n  \u003cli\u003eRound cross section, Dash 203 standard sizing for consistent fitment\u003c\/li\u003e\n  \u003cli\u003eGood resistance to petroleum products and a wide range of industrial chemicals\u003c\/li\u003e\n  \u003cli\u003eLow gas permeability and suitable for vacuum service applications\u003c\/li\u003e\n  \u003cli\u003ePackaged 25 per unit to support service stock and bulk repair work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 203 O-ring replacement for use in petroleum-compatible fluid and gas sealing applications across HVAC, plumbing, hydraulic, and industrial systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians, plumbers, or mechanical service technicians. Always depressurize and drain the system before removing or replacing O-rings to prevent fluid or gas release. Inspect the mating groove for nicks, corrosion, or debris before seating the new O-ring. Consult applicable codes such as the IFGC or IPC for gas and plumbing system service requirements.\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: 203\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.313 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.563 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\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\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25\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: ZMSCV70203\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715457057074,"sku":"ZMSCV70203","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45181f4e70f20f42b1fc3c387322ab02.jpg?v=1788514240","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70203-viton-o-ring-dash-203-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
