With an inside diameter of 1.313 inches, an outside diameter of 1.563 inches, and a thickness of 0.125 inches, this round cross-section ring provides a dependable seal in systems where temperature extremes and ozone or weather exposure are primary concerns. Rated for service from -80 degrees F to 450 degrees F, it is well suited for dry heat environments and general industrial sealing tasks. Each order includes 50 rings per package.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is appropriate for use in HVAC, plumbing, and general mechanical assemblies where silicone elastomers are specified. It performs in applications involving exposure to oils, chemicals, and solvents, though users should note its oil resistance is limited compared to nitrile or EPDM compounds. It is commonly installed by HVAC technicians, plumbers, and industrial maintenance professionals in fittings, valves, pumps, and fluid system connections that require broad temperature tolerance and reliable weather resistance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWide service temperature range: -80 degrees F to 450 degrees F for demanding thermal environments\u003c\/li\u003e\n  \u003cli\u003eRound cross-section silicone construction with a 70 Shore A hardness rating\u003c\/li\u003e\n  \u003cli\u003eGood resistance to ozone, weather, and dry heat degradation\u003c\/li\u003e\n  \u003cli\u003eCompatible with oils, chemicals, and solvents (limited oil resistance — verify suitability for heavy oil exposure)\u003c\/li\u003e\n  \u003cli\u003eWhite color aids visual inspection during installation\u003c\/li\u003e\n  \u003cli\u003eSold in a 50-piece package with a minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 219 O-ring replacement suitable for fittings, valves, pumps, and fluid system components specifying a silicone elastomer seal with 1.313 inches ID and 1.563 inches OD.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eO-rings of this type are installed by licensed HVAC technicians, journeyman plumbers, and qualified mechanical service personnel. Always depressurize and de-energize the system before replacing any seal. Inspect the groove for nicks or burrs that could compromise the seal surface. Use only a compatible lubricant rated for silicone elastomers — petroleum-based greases can degrade silicone over time.\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: 219\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.313 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.563 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 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 oil resistance)\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: 50\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: ZMSCS70219\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695723151666,"sku":"ZMSCS70219","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/792989f58b47d995e8f20d92a317784f_e03c39f6-5bad-45e8-b577-2e0dd2ae834c.jpg?v=1788337761","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70219-silicone-o-ring-dash-219-50pk","provider":"Voomi Supply","version":"1.0","type":"link"}
