It features a 5.5-inch inside diameter, a 5.875-inch outside diameter, and a 0.1875-inch (3\/16 inches) cross-section thickness. Silicone compound gives this seal strong resistance to dry heat, weathering, and ozone exposure. It is suited for static sealing applications across HVAC, plumbing, pool equipment, and general industrial systems. Licensed tradespeople and maintenance technicians install this ring where a reliable, heat-tolerant seal is required.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is rated for use with oils, chemicals, and solvents, though oil resistance is limited compared to nitrile or fluorocarbon compounds. It is appropriate for residential and commercial applications where wide temperature swings and outdoor ozone exposure are concerns, such as chiller fittings, pump housings, valve assemblies, and pool equipment sealing points. Each order ships in a package of 5 rings. This is a hard-rated silicone seal and is not FDA approved.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicone compound rated -80 degrees F to 450 degrees F operating range\u003c\/li\u003e\n  \u003cli\u003e70 durometer hardness with round cross-section profile\u003c\/li\u003e\n  \u003cli\u003eGood resistance to weathering, ozone, and dry heat\u003c\/li\u003e\n  \u003cli\u003eCompatible with oils, chemicals, and solvents (limited oil resistance)\u003c\/li\u003e\n  \u003cli\u003eDash 357 industry-standard sizing for straightforward replacement sourcing\u003c\/li\u003e\n  \u003cli\u003eSold in a package of 5 rings per order unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 357 O-ring replacement for static sealing applications in HVAC, plumbing, pool, and general industrial equipment requiring a 5.5-inch ID silicone seal.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eO-rings of this size are typically installed by licensed HVAC technicians, plumbers, or pool service professionals. Shut down and depressurize the system fully before removing any fittings or housings. Seat the ring evenly in the groove without twisting or stretching; a light coating of compatible lubricant helps prevent roll-out during assembly. Verify the groove dimensions match the Dash 357 specification before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\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\u003eDash Number\u003c\/strong\u003e: 357\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 Durometer\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\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: ZMSCS70357\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720238301490,"sku":"ZMSCS70357","price":18.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_9a56a303-7829-4aec-86f7-2992ab1322ec.jpg?v=1788561789","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70357-silicone-o-ring-dash-357","provider":"Voomi Supply","version":"1.0","type":"link"}
