It measures 2.75 inches inside diameter, 2.875 inches outside diameter, and 0.0625 inches thick. Rated at 70 Shore hardness, this O-ring handles a wide service temperature range from -80 degrees F to 450 degrees F, making it well-suited for applications requiring dry heat resistance and stable sealing performance across temperature extremes. Plumbers, HVAC technicians, and maintenance professionals install this type of O-ring as a static or low-motion face seal or radial seal in fluid and gas systems. Each package contains 10 O-rings.\u003c\/p\u003e\u003cp\u003eThis silicone O-ring is appropriate for use in residential and commercial systems where good weather resistance, ozone resistance, and moderate chemical compatibility are required. Silicone material provides good resistance to oils, certain chemicals, and solvents, though oil resistance is limited compared to nitrile or fluorocarbon alternatives. Typical applications include HVAC equipment fittings, plumbing connections, and general industrial assemblies that see elevated or sub-zero temperatures. This O-ring is not FDA approved and should not be used in food-contact applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTemperature range of -80 degrees F to 450 degrees F for wide thermal envelope coverage\u003c\/li\u003e\n\u003cli\u003e70 Shore hardness (Hard rating) for firm, reliable compression sealing\u003c\/li\u003e\n\u003cli\u003eRound cross section for standard groove compatibility\u003c\/li\u003e\n\u003cli\u003eSilicone material provides good weather and ozone resistance\u003c\/li\u003e\n\u003cli\u003eCompatible with oils, certain chemicals, and solvents; limited oil resistance noted\u003c\/li\u003e\n\u003cli\u003eSold in a pack of 10 for service and maintenance stocking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 039 O-ring replacement for any system or fitting that accepts a 2.75 inches ID round-cross-section O-ring in silicone material.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified plumber, HVAC technician, or maintenance professional after depressurizing and draining the system. Inspect the seating groove for damage, debris, or wear before installing the new O-ring. Avoid twisting or stretching the O-ring during installation, as distortion can lead to premature seal failure. Confirm material compatibility with the system fluid or gas before installation, particularly in applications with prolonged hydrocarbon oil exposure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Silicone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 039\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: -80 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 450 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible With\u003c\/strong\u003e: Oils, Chemicals, Solvents (limited oil resistance)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10\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: ZMSCS70039\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698038669618,"sku":"ZMSCS70039","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/508aa4154a75a06a9a74ddf3a3741320.jpg?v=1788357014","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70039-silicone-o-ring-dash-039","provider":"Voomi Supply","version":"1.0","type":"link"}
