Rated at 70 Shore A hardness, it provides firm sealing force under compression with excellent resistance to petroleum-based fluids. Operating temperature range spans -40 degrees F to 250 degrees F, making it suitable for a broad range of fluid-handling and mechanical sealing applications. Licensed HVAC techs, plumbers, and industrial mechanics reach for this elastomer first when sealing oil, fuel, or hydraulic connections. Sold in a pack of 50 units.\u003c\/p\u003e\n\u003cp\u003eBuna-N is the most widely used O-ring elastomer in the trade. This Dash 142 size appears in residential and light commercial HVAC equipment, refrigeration systems, plumbing valves, hydraulic fittings, fuel-system components, and general industrial assemblies wherever a reliable static or dynamic face seal or radial seal is needed against petroleum-based media. The black color and standard SAE and MIL-Spec dimensional compliance make it a straightforward drop-in for maintenance, repair, and overhaul work across a wide range of equipment types.\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, oils, and fuels\u003c\/li\u003e\n  \u003cli\u003e70 Shore A durometer (Hard rating) delivers reliable compression set and sealing force\u003c\/li\u003e\n  \u003cli\u003eRound cross section; 0.0937-inch (3\/32-inch) thickness conforms to standard Dash 142 dimensions\u003c\/li\u003e\n  \u003cli\u003eTemperature range of -40 degrees F to 250 degrees F suits most HVAC, plumbing, and hydraulic service environments\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec dimensional standards for broad equipment compatibility\u003c\/li\u003e\n  \u003cli\u003ePack of 50 supports fleet service, shop stock, and high-volume MRO replenishment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 142 O-ring replacement compatible with petroleum-based fluid systems; not compatible with ozone-generating environments, direct sunlight storage, or applications requiring FDA-approved elastomers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians, plumbers, or industrial mechanics. Always depressurize and evacuate the system and remove residual fluid before replacing seals. Lightly lubricate the O-ring with a compatible oil or grease prior to installation to prevent rolling or pinching in the groove. Do not store unused O-rings near motors, electrical equipment, or in direct sunlight, as ozone and UV exposure degrade Buna-N over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Buna-N (Nitrile Butadiene Rubber)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 142\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.563 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Thickness\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 (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 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\u003eStandards\u003c\/strong\u003e: SAE, MIL-Spec\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50\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\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: ZMSCH70142\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692809814322,"sku":"ZMSCH70142","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5462e0c6c9186776a681eaf791164c27.jpg?v=1788303282","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70142-o-ring-dash-142-nbr-70-duro-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
