Measuring 1.0625 inches inside diameter, 1.25 inches outside diameter, and 0.0937 inches thick with a round cross-section, this O-ring carries a Shore A hardness of 70. It performs reliably from -15 degrees F up to 400 degrees F, making it suitable for demanding industrial and mechanical sealing environments. Licensed tradespeople including plumbers, HVAC technicians, and industrial mechanics install these as static or dynamic seals in fluid and gas systems. Each order contains 50 pieces.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for use in systems handling petroleum products, hydraulic fluids, and other media compatible with fluoroelastomer compounds. The Dash 121 designation places it in a standard AS568 size series, making it a common fit for valves, fittings, pumps, cylinders, and similar components found in residential and commercial mechanical systems. Its low gas permeability and suitability for vacuum service extend its usefulness to refrigeration and HVAC applications where seal integrity is critical. The black color is standard for Viton compounds of this hardness rating.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFluoroelastomer (Viton) material offers wide-spectrum chemical compatibility\u003c\/li\u003e\n  \u003cli\u003eOperating range of -15 degrees F to 400 degrees F suits high-temperature service\u003c\/li\u003e\n  \u003cli\u003eGood resistance to petroleum products and hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003eLow compression set maintains sealing force over extended service life\u003c\/li\u003e\n  \u003cli\u003eLow gas permeability and rated for vacuum service\u003c\/li\u003e\n  \u003cli\u003eRound cross-section, standard Dash 121 AS568 sizing for straightforward replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with systems and components handling petroleum products and chemicals within the rated temperature range.

Always de-energize or depressurize the system and allow components to cool before replacing seals. Lubricate the O-ring with a compatible grease or fluid before installation to prevent tearing during assembly. Inspect the gland for nicks or corrosion that could compromise the seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Fluoroelastomer (Viton)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 121\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0937 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\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: -15 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 400 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Media\u003c\/strong\u003e: Petroleum Products\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\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 pieces\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: ZMSCV70121\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720594424114,"sku":"ZMSCV70121","price":22.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3d55bc62bc8f539017d6471964337a98.jpg?v=1788566631","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70121-viton-o-ring-dash-121-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
