Buna-N is the most widely used O-ring elastomer in trade applications, valued for its excellent resistance to petroleum-based fluids, strong compression set performance, and solid tear and abrasion resistance. This O-ring features a round cross-section profile and a Shore A hardness of 70, classifying it as a hard-durometer seal. It is sold in a package of 100 units. Licensed plumbers, HVAC technicians, and mechanical contractors commonly use this size in hydraulic, pneumatic, and fluid-handling assemblies.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for residential and commercial applications where petroleum-product compatibility is required. Typical install scenarios include pump seals, valve bodies, fittings, and fluid connectors in HVAC, plumbing, and general mechanical systems. The Buna-N compound performs across a wide temperature range, making it appropriate for both indoor and outdoor service conditions within rated limits. Compatible materials include petroleum-based oils, fuels, and hydraulic fluids commonly found in mechanical trade systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBuna-N (NBR) elastomer offers excellent resistance to petroleum products and hydraulic fluids\u003c\/li\u003e\n\u003cli\u003eRound cross-section profile ensures consistent seating and reliable compression seal\u003c\/li\u003e\n\u003cli\u003eShore A hardness of 70 provides a hard-durometer rating suitable for higher-pressure sealing applications\u003c\/li\u003e\n\u003cli\u003eRated from -40 degrees F to 250 degrees F for broad temperature service range\u003c\/li\u003e\n\u003cli\u003eMeets SAE and MIL-Spec standards for quality and dimensional consistency\u003c\/li\u003e\n\u003cli\u003ePackage quantity of 100 units supports job-site stocking and service fleet inventory\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with petroleum products including oils, fuels, and hydraulic fluids.

Always depressurize and isolate the fluid circuit before removing or installing O-rings. Inspect the gland and mating surfaces for nicks or corrosion prior to seating the new O-ring. Do not store Buna-N O-rings near motors, ozone-generating equipment, or in direct sunlight, as ozone and UV exposure degrade NBR compound over time.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 034\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2.125 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 (Cross Section)\u003c\/strong\u003e: 0.0625 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 (Shore A)\u003c\/strong\u003e: 70\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\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Material\u003c\/strong\u003e: Petroleum Products\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: 0.02 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: ZMSCH70034\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720761573682,"sku":"ZMSCH70034","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2aaa3804202e43c411079afe8851ab52.jpg?v=1788568763","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70034-o-ring-dash-034-nbr-pack-of-100","provider":"Voomi Supply","version":"1.0","type":"link"}
