The round cross-section ring measures 0.625 inches inside diameter, 1.000 inches outside diameter, and 0.1875 inches thick. With a Shore A hardness of 70 and a working temperature range of -80 degrees F to 450 degrees F, this O-ring is suited for applications that demand wide thermal tolerance and reliable dry heat resistance. Licensed trades and maintenance technicians install this part as a sealing component in fluid-handling assemblies, valve bodies, and mechanical fittings. Each package contains 10 O-rings.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is appropriate for residential and commercial installations where silicone sealing material is specified. Typical applications include HVAC equipment service ports, plumbing valve seats, pump housings, and other assemblies exposed to oils, chemicals, or solvents. The silicone compound provides good weather and ozone resistance, making it suitable for both indoor and outdoor service environments. It is not rated for high-oil-concentration environments where nitrile or fluorocarbon compounds would be preferred. Installers should verify Dash 312 sizing matches the gland specifications before installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicone compound rated for a wide temperature range of -80 degrees F to 450 degrees F\u003c\/li\u003e\n  \u003cli\u003eRound cross-section profile in standard Dash 312 size for consistent gland fit\u003c\/li\u003e\n  \u003cli\u003eShore A hardness of 70 for firm sealing under compression\u003c\/li\u003e\n  \u003cli\u003eGood weather and ozone resistance for indoor and outdoor service use\u003c\/li\u003e\n  \u003cli\u003eCompatible with oils, chemicals, and solvents in limited concentrations\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 10 to support service calls and repair stock\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 312 O-ring replacement for any gland or groove machined to the Dash 312 dimensional standard, including valve bodies, fittings, pump housings, and mechanical assemblies requiring a 0.625-inch inside diameter silicone seal.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians, plumbers, or qualified mechanical trades. Depressurize and isolate the system before removing any existing seal or fitting. Inspect the gland or groove for wear, scoring, or contamination before seating the new O-ring. Do not use petroleum-based lubricants with silicone O-rings; use a silicone-compatible lubricant only to ease installation and reduce the risk of tearing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Silicone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 312\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.6250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness (Cross Section)\u003c\/strong\u003e: 0.1875 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: -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 Media\u003c\/strong\u003e: Oils, Chemicals, Solvents (limited concentration)\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: 10\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: ZMSCS70312\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716305092914,"sku":"ZMSCS70312","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_29eb58d2-c250-42a3-9d9f-70024c0035ba.jpg?v=1788524115","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70312-silicone-o-ring-dash-312","provider":"Voomi Supply","version":"1.0","type":"link"}
