Rated at 70 Shore A hardness, this O-ring is built for applications that demand a wide operating temperature range, running from -80 degrees F to 450 degrees F. Silicone construction provides solid resistance to dry heat, weathering, and ozone. Licensed trades and maintenance technicians install these in sealing applications where thermal cycling or outdoor exposure is a primary concern. Each package contains 5 O-rings.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for use in HVAC, plumbing, and industrial equipment where large-bore sealing is required. The silicone compound performs well in dry-heat environments, outdoor-exposed assemblies, and systems subject to temperature extremes. It carries limited oil resistance, making it a better fit for air, gas, or mild chemical service than for continuous petroleum-fluid contact. Typical install scenarios include large valve bodies, pump housings, access covers, and flanged connections that call for a Dash 356 profile.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicone material rated for -80 degrees F to 450 degrees F operating temperature range\u003c\/li\u003e\n  \u003cli\u003eRound cross-section, Dash 356 sizing: 5.375 inches ID, 5.75 inches OD, 0.1875 inches thick\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness for firm, reliable compression sealing\u003c\/li\u003e\n  \u003cli\u003eGood resistance to weathering, ozone, and dry heat\u003c\/li\u003e\n  \u003cli\u003eCompatible with oils, certain chemicals, and solvents with noted limitations on petroleum-fluid exposure\u003c\/li\u003e\n  \u003cli\u003eSold in a pack of 5, minimum order quantity of 1 pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style or aftermarket replacement O-ring for any application calling for a Dash 356 round cross-section silicone seal with a 5.375-inch inside diameter and 0.1875-inch cross-section thickness.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians, plumbers, or maintenance mechanics. Always depressurize and isolate the system before removing the old O-ring and seating the replacement. Inspect the groove and mating surfaces for nicks or corrosion that could compromise the seal. Avoid using petroleum-based lubricants with silicone O-rings; use a silicone-compatible assembly lubricant if needed to seat the ring without rolling or twisting it.\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: 356\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 5.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross-Section Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 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\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  \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: ZMSCS70356\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699937542450,"sku":"ZMSCS70356","price":17.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_9068a219-1366-4356-b01c-c7d2e6d5bc5a.jpg?v=1788383681","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70356-silicone-o-ring-dash-356-5pk","provider":"Voomi Supply","version":"1.0","type":"link"}
