It carries a Dash 274 designation and a Shore A hardness of 70, placing it in the hard hardness rating category. Silicone compound makes this O-ring well suited for applications that demand a wide service temperature range, from -80 degrees F to 450 degrees F, along with reliable dry heat, weather, and ozone resistance. Plumbers, HVAC technicians, and industrial maintenance trades use this type of seal where thermal cycling or outdoor exposure are primary concerns.\u003c\/p\u003e\u003cp\u003eThis O-ring is appropriate for static and low-movement sealing applications in residential and commercial mechanical systems. Its silicone material offers compatibility with oils, certain chemicals, and solvents, though users should note that oil resistance is limited and the material is not FDA approved. Typical install scenarios include pipe flanges, pump housings, valve bodies, and equipment covers where a large-diameter face seal or radial seal is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSilicone compound rated for service temperatures from -80 degrees F to 450 degrees F\u003c\/li\u003e\n\u003cli\u003eRound cross section, 0.125 inches thick, for consistent seating in standard O-ring grooves\u003c\/li\u003e\n\u003cli\u003eDash 274 designation for straightforward cross-reference and replacement sourcing\u003c\/li\u003e\n\u003cli\u003eShore A hardness of 70 (hard rating) for firm compression and reliable sealing\u003c\/li\u003e\n\u003cli\u003eCompatible with oils, chemicals, and solvents; limited oil resistance applies\u003c\/li\u003e\n\u003cli\u003eGood weather and ozone resistance for outdoor or exposed installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 274 replacement O-ring for any application requiring a 10-inch ID silicone seal with a 0.125-inch cross section thickness.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified plumber, HVAC technician, or industrial maintenance technician. Depressurize and drain the system fully before removing the old seal and installing the replacement. Inspect the O-ring groove for nicks, corrosion, or debris that could cause leakage or damage the new seal. Lubricate the O-ring with a compatible silicone-based lubricant before seating to prevent tearing during assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 10.25 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: 274\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\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 70 Shore A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: 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\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31401503\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: ZMSCS70274\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693344457010,"sku":"ZMSCS70274","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_da7802cd-3447-462c-a9e4-4809a034810b.jpg?v=1788310983","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70274-silicone-o-ring-dash-274","provider":"Voomi Supply","version":"1.0","type":"link"}
