It measures 6.75 inches inside diameter and 7.125 inches outside diameter, with a wall thickness of 0.1875 inches. The compound is rated at 70 durometer hardness, placing it in the hard range on the Shore A scale. Silicone construction gives this O-ring a working temperature range of -80 degrees F to 450 degrees F, making it suitable for high-heat and wide-range thermal cycling environments where standard nitrile or EPDM compounds fall short.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is appropriate for use in residential and commercial equipment where good dry heat resistance, weather resistance, and ozone resistance are required. Typical applications include furnace and air handler seal points, pump housings, valve bodies, and equipment exposed to outdoor conditions or elevated temperatures. The material offers limited oil resistance, so it is best suited for dry or chemical environments rather than petroleum-fluid systems. Compatible materials include oils in low-exposure contexts, chemicals, and solvents as noted in the manufacturer specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicone compound rated for -80 degrees F to 450 degrees F continuous service\u003c\/li\u003e\n  \u003cli\u003e70 durometer hardness for firm, reliable sealing under compression\u003c\/li\u003e\n  \u003cli\u003eRound cross section conforms to standard O-ring groove dimensions for Dash 364\u003c\/li\u003e\n  \u003cli\u003eGood weather and ozone resistance for outdoor or exposed installations\u003c\/li\u003e\n  \u003cli\u003eCompatible with chemicals and solvents; limited oil resistance noted\u003c\/li\u003e\n  \u003cli\u003eWhite color for visual inspection and identification in the field\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 364 O-ring replacement for any equipment or assembly specifying a 6.75-inch ID silicone O-ring with a 0.1875-inch cross section thickness.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlumbers, HVAC technicians, and industrial service technicians install O-rings of this type during equipment teardown and reassembly. Always depressurize and de-energize the system before replacing seals. Inspect the mating groove for burrs, corrosion, or debris before seating the new O-ring, and do not use petroleum-based lubricants with silicone compounds unless confirmed compatible with the system fluid. Follow applicable codes such as the IPC or IFGC for sealed connections in gas and plumbing systems.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 6.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 7.125 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\u003eDash Number\u003c\/strong\u003e: 364\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 (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 (limited), Chemicals, Solvents\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: ZMSCS70364\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714558722354,"sku":"ZMSCS70364","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7d9085bf314ec85d93e2122413e997a4.jpg?v=1788503198","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70364-silicone-o-ring-dash-364","provider":"Voomi Supply","version":"1.0","type":"link"}
