It features a round cross section with a 3.75-inch inside diameter, 4-inch outside diameter, and a thickness of 0.125 inches. Rated at 70 Shore A hardness, this O-ring is formulated for wide temperature range service, rated from -80 degrees F to 450 degrees F. It carries good resistance to dry heat, weather, and ozone. Licensed plumbers, HVAC technicians, and industrial maintenance professionals install these as static or low-motion seals in fluid and gas systems.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for applications requiring broad thermal tolerance and reliable sealing against oils, chemicals, and solvents. Silicone compound makes it a common choice in HVAC, refrigeration, plumbing, and general industrial assemblies where temperature extremes or outdoor exposure are concerns. Note that this compound has limited oil resistance compared to Buna-N or Viton, so confirm compatibility with your specific fluid media before installation. Each order ships as a pack of 5 individual O-rings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDash 240 size: 3.75 inches ID, 4 inches OD, 0.125 inches thick\u003c\/li\u003e\n\u003cli\u003eSilicone compound rated from -80 degrees F to 450 degrees F\u003c\/li\u003e\n\u003cli\u003e70 Shore A hardness rating for firm, reliable sealing\u003c\/li\u003e\n\u003cli\u003eGood weather and ozone resistance for outdoor or exposed installations\u003c\/li\u003e\n\u003cli\u003eCompatible with oils, chemicals, and solvents in appropriate concentrations\u003c\/li\u003e\n\u003cli\u003eRound cross section for use in standard O-ring groove profiles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 240 O-ring replacement for any application calling for a 3.75-inch ID silicone seal with a 0.125-inch cross section.

Clean the mating groove of debris and inspect for surface damage that could compromise the seal. Apply a compatible lubricant sparingly to ease seating without overstretching the O-ring. Silicone O-rings should not be used with silicone-based greases or fluids, as these can cause swelling and seal failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 240\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: Silicone\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: -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\u003eCompatible With\u003c\/strong\u003e: Oils, Chemicals, Solvents\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\u003ePackage Quantity\u003c\/strong\u003e: 5\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: ZMSCS70240\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723298046258,"sku":"ZMSCS70240","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_cd86e54b-0c2e-4b7a-8851-e5cce9cffd27.jpg?v=1788602846","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70240-silicone-o-ring-dash-240-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
