Rated at 90 durometer (extra hard), this O-ring is engineered for high-compression sealing applications where firm resistance to deformation is critical. It carries a working temperature range of -40 to 250 degrees F and is compatible with petroleum-based fluids. Licensed HVAC technicians, plumbers, and mechanical contractors regularly specify Buna-N O-rings for sealing refrigerant fittings, hydraulic connections, fuel lines, and water system components. Sold in a pack of 100 units.\u003c\/p\u003e\u003cp\u003eBuna-N is the most widely used O-ring elastomer in trade applications. This O-ring is suited for use in residential and commercial HVAC systems, plumbing assemblies, hydraulic equipment, and pneumatic fittings where petroleum-based fluid exposure is expected. The 90-durometer hardness makes it appropriate for high-pressure sealing scenarios where softer elastomers would extrude or deform under load. Typical installation scenarios include pump seals, valve stems, union connections, and compression fittings across plumbing and mechanical systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBuna-N (Nitrile Butadiene Rubber) elastomer with excellent resistance to petroleum products\u003c\/li\u003e\n\u003cli\u003e90 durometer extra-hard rating resists compression set, tear, and abrasion\u003c\/li\u003e\n\u003cli\u003eTemperature range: -40 to 250 degrees F for broad system compatibility\u003c\/li\u003e\n\u003cli\u003eRound cross-section at 0.0625 inches (1.78 mm) thickness for standard Dash 035 groove fitment\u003c\/li\u003e\n\u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n\u003cli\u003ePack of 100 units for service inventory or production use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard Dash 035 O-ring grooves.

Inspect the mating groove for burrs or wear before seating the new O-ring. A light application of compatible lubricant aids seating and reduces the risk of nicking during assembly. Store unused O-rings away from direct sunlight, ozone sources, and electrical equipment that may generate ozone, such as motors.\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\u003eInside Diameter\u003c\/strong\u003e: 2.25 inches (56.87 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.375 inches (60.32 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0625 inches (1.78 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 035\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 90 Durometer (Extra 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\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: 0.54 pounds\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: ZMSCH90035\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701681094962,"sku":"ZMSCH90035","price":21.64,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e63e5be40384736fb1f090e4d0cdd585_bf678e3d-c3be-45fc-adba-7859a34dfec2.jpg?v=1788403645","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch90035-o-ring-dash-035-nbr-90-duro","provider":"Voomi Supply","version":"1.0","type":"link"}
