The round cross-section profile measures 2.0625 inches inside diameter, 2.25 inches outside diameter, and 0.0937 inches thick. Made from white silicone with a Shore A hardness of 70, this O-ring holds a seal across an operating range of -80 degrees F to 450 degrees F. Licensed technicians and pipefitters install these during equipment repair, valve service, and pump overhaul work where consistent sealing performance under thermal cycling is required.\u003c\/p\u003e\u003cp\u003eThis O-ring suits applications that demand wide temperature tolerance and good dry heat resistance. It performs well in environments with exposure to weather and ozone. Oil resistance is limited, so it is best suited for non-petroleum fluid paths or dry-heat service points. Typical uses include HVAC equipment fittings, water handling assemblies, and light chemical service connections where a silicone compound is specified by the equipment manufacturer. Each package contains 10 O-rings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOperating range from -80 degrees F to 450 degrees F suits extreme thermal cycling environments\u003c\/li\u003e\n\u003cli\u003eRound cross-section profile ensures consistent compression and seal contact\u003c\/li\u003e\n\u003cli\u003eShore A hardness of 70 rated as hard provides stable sealing under moderate mechanical load\u003c\/li\u003e\n\u003cli\u003eGood weather and ozone resistance extends service life in outdoor or exposed installations\u003c\/li\u003e\n\u003cli\u003eCompatible with oils, select chemicals, and solvents where silicone compounds are appropriate\u003c\/li\u003e\n\u003cli\u003ePackaged in quantities of 10 for bench stock and service van inventory\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 137 O-ring replacement for any application calling out a Dash 137 silicone seal with a 2.0625 inches inside diameter and 0.0937 inches cross-section thickness.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by licensed HVAC technicians, plumbers, or pipefitters. Depressurize and isolate the fluid circuit completely before removing the existing O-ring. Inspect the groove and mating surfaces for scoring or contamination before seating the replacement. Do not use petroleum-based lubricants with silicone O-rings; use a silicone-compatible assembly lubricant if needed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2.0625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0937 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 137\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\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\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: 10\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: ZMSCS70137\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51712643596594,"sku":"ZMSCS70137","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c892aecc74008d80f9dc7a220de0b0dd.jpg?v=1788487257","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70137-silicone-o-ring-dash-137","provider":"Voomi Supply","version":"1.0","type":"link"}
