It measures 4.875 inches inside diameter, 5.125 inches outside diameter, and 0.125 inches thick with a round cross section. The silicone compound is rated for a working temperature range of -80 degrees F to 450 degrees F, making it well suited for applications that demand wide thermal tolerance and good dry heat resistance. Hardness is rated at 70 Shore A. This O-ring is used by plumbers, HVAC technicians, and industrial maintenance trades wherever a reliable face or radial seal is required.\u003c\/p\u003e\u003cp\u003eThis O-ring fits applications where silicone elastomer is the specified compound, including fluid handling assemblies, pump housings, valve bodies, and HVAC equipment that operate across wide temperature swings. Silicone provides good weather and ozone resistance, making it appropriate for both indoor and outdoor service environments. It offers limited oil resistance, so it is best suited for water, air, and dry-heat service rather than petroleum-heavy applications. Each package contains 5 O-rings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSilicone compound rated from -80 degrees F to 450 degrees F for wide thermal range service\u003c\/li\u003e\n\u003cli\u003eRound cross section, 0.125 inches thick, for standard groove fitment\u003c\/li\u003e\n\u003cli\u003e70 Shore A hardness — rated Hard — for positive sealing under compression\u003c\/li\u003e\n\u003cli\u003eGood weather and ozone resistance extends service life in exposed installations\u003c\/li\u003e\n\u003cli\u003eCompatible with oils, chemicals, and solvents per manufacturer specifications; limited oil resistance noted\u003c\/li\u003e\n\u003cli\u003ePackaged in quantities of 5 to support single-job or stock replenishment needs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 249 O-ring replacement for any application specifying a 4.875 inches ID silicone O-ring with a 0.125-inch cross section.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eO-ring installation is typically performed by licensed plumbers, HVAC technicians, or qualified maintenance personnel. Before replacing any O-ring, relieve all system pressure and shut off fluid supply to the assembly being serviced. Lubricate the O-ring with a compatible lubricant before installation to prevent tearing during seating. Do not roll or twist the O-ring into the groove; seat it evenly to ensure a uniform seal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 4.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5.125 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\u003eDash Number\u003c\/strong\u003e: 249\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 With\u003c\/strong\u003e: Oils, Chemicals, Solvents (limited oil resistance)\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: ZMSCS70249\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714884665650,"sku":"ZMSCS70249","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_2c089894-ce75-4b58-9f62-ce880d640cac.jpg?v=1788507402","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70249-silicone-o-ring-dash-249-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
