It measures 1.0625 inches inside diameter, 1.2500 inches outside diameter, and 0.0937 inches thick. With a 70 Shore A durometer hardness rating, this O-ring provides firm, reliable compression set performance. Rated for service from -65 degrees F to 250 degrees F, it handles the thermal cycling common in refrigeration and air conditioning circuits. Sold in a pack of 100, it is suited for technicians stocking parts for recurring seal replacements.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is appropriate for residential and light commercial refrigeration, air conditioning, and plumbing systems where neoprene compound compatibility is required. Neoprene offers moderate resistance to petroleum-based fluids and good resistance to ozone and weathering, making it a practical choice for outdoor or exposed service environments. It is particularly well suited for sealing refrigeration circuits handling Freon-type refrigerants. HVAC technicians and plumbers will find this a reliable shelf-stock seal for Dash 121 groove applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDash 121 standard sizing: 1.0625 inches ID, 1.2500 inches OD, 0.0937 inches thick\u003c\/li\u003e\n  \u003cli\u003eNeoprene compound rated for Freon refrigerant compatibility\u003c\/li\u003e\n  \u003cli\u003eOperating range of -65 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e70 Shore A durometer hardness for reliable compression set in sealing grooves\u003c\/li\u003e\n  \u003cli\u003eGood ozone and weather resistance for exposed or outdoor applications\u003c\/li\u003e\n  \u003cli\u003ePack of 100 units suitable for bulk stocking by service contractors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement neoprene O-ring for Dash 121 groove applications in refrigeration, HVAC, and plumbing systems where neoprene compound seals are specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians or plumbers as part of a seal replacement or system reassembly procedure. Always depressurize and evacuate the system before replacing O-rings in refrigeration or refrigerant-handling circuits. Lightly lubricate the O-ring with a compatible refrigerant oil or seal lubricant before seating to prevent tearing during installation. Do not reuse a removed O-ring; replace with a fresh seal every time the joint is opened.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Neoprene\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 (1-1\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.2500 inches (1-1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0937 inches (3\/32 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\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: -65 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Fluid\u003c\/strong\u003e: Freon-type refrigerants\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: 100\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: ZMSCN70121\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51712673481010,"sku":"ZMSCN70121","price":20.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a85a04616a0b8edf3ad2b4aa4905ae64_2e33c946-cefb-4a2c-8966-fa6ab40665f6.jpg?v=1788487570","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscn70121-neoprene-o-ring-dash-121-100-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
