It features a round cross section with an inside diameter of 1.0625 inches, an outside diameter of 1.25 inches, and a thickness of 0.0937 inches. With a durometer hardness rating of 70 Shore A, this O-ring delivers firm compression set resistance and solid tear and abrasion performance. It is sold in a package quantity of 100 rings. Licensed plumbers, pipefitters, hydraulic technicians, and HVAC mechanics are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for use in hydraulic systems, pneumatic assemblies, plumbing connections, and HVAC equipment where petroleum-based fluids or lubricants are present. Its Buna-N compound provides excellent resistance to petroleum products, making it a practical choice for fuel lines, oil circuits, and general-purpose fluid connections in both residential and light commercial service environments. The operating temperature range of -40 degrees F to 250 degrees F covers most standard HVAC, plumbing, and hydraulic applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) material offers excellent resistance to petroleum products and oils\u003c\/li\u003e\n  \u003cli\u003eRound cross section with 0.0937 inch thickness ensures consistent sealing under compression\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness rating provides firm compression set and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003eOperating range from -40 degrees F to 250 degrees F suits most trade applications\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003eSold in a 100-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 121 replacement O-ring compatible with petroleum-based fluid systems.

Always depressurize and drain the system before replacing O-rings, and shut off all fluid supply valves upstream of the work area. Lubricate the O-ring with a compatible petroleum-based lubricant before seating to prevent tearing during installation. Do not store unused O-rings in direct sunlight or near motors or other electrical equipment that may generate ozone, as this will degrade the Buna-N compound.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nitrile Butadiene Rubber (Buna-N)\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\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: -40 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 Material\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\u003eStandards\u003c\/strong\u003e: SAE, MIL-Spec\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\u003eWeight\u003c\/strong\u003e: 0.18 pounds\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: ZMSCH70121\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715934486834,"sku":"ZMSCH70121","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/844bc6a0777a970377619523f58f0b7e.jpg?v=1788519909","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70121-o-ring-dash-121-nbr-pack-of-100","provider":"Voomi Supply","version":"1.0","type":"link"}
