Manufactured from Nitrile Butadiene Rubber (Buna-N), this O-ring measures 1.355 inches inside diameter, 1.587 inches outside diameter, and 0.116 inches thick with a round cross section. The 70 Shore A hardness rating delivers a firm, consistent seal with strong compression set resistance and good tear and abrasion resistance. Licensed plumbers, hydraulic technicians, and millwrights routinely specify Buna-N for petroleum-based fluid circuits. This part is packaged in a quantity of 100.\u003c\/p\u003e\u003cp\u003eThis O-ring is well suited for straight-thread tube fitting boss gasket applications and any plumbing or hydraulic assembly exposed to petroleum-based fluids. The Buna-N compound offers excellent resistance to oils, fuels, and greases across a wide service temperature range of -40 degrees F to 250 degrees F. Residential and commercial plumbing systems, hydraulic power units, and fuel handling equipment represent typical install environments. The Dash 918 sizing is a standard dimension that appears across a broad range of OEM fittings and aftermarket assemblies. Meets SAE and MIL-Spec standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBuna-N (Nitrile Butadiene Rubber) construction — the most widely used O-ring elastomer for petroleum-service applications\u003c\/li\u003e\n\u003cli\u003eDash 918 standard sizing: 1.355 inches ID, 1.587 inches OD, 0.116 inches thick\u003c\/li\u003e\n\u003cli\u003e70 Shore A hardness with round cross section for predictable seating and compression\u003c\/li\u003e\n\u003cli\u003eRated for service from -40 degrees F to 250 degrees F\u003c\/li\u003e\n\u003cli\u003eCompatible with petroleum products including oils, fuels, and hydraulic fluids\u003c\/li\u003e\n\u003cli\u003eMeets SAE and MIL-Spec standards; sold in a pack of 100\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service stock O-ring for straight-thread tube fitting boss gasket applications in hydraulic, pneumatic, and plumbing systems where a Dash 918 Buna-N seal is specified. Compatible with petroleum-based media. Not recommended for use with ozone, strong oxidizing agents, or direct sunlight exposure during storage.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by licensed plumbers, hydraulic technicians, or qualified HVAC and refrigeration mechanics depending on the application. Depressurize and drain the system completely before removing the old O-ring to prevent fluid release or injury. Lightly lubricate the O-ring with a compatible petroleum-based fluid before seating to prevent nicking or rolling during assembly. Do not store O-rings near motors, electrical equipment, or in direct sunlight, as ozone and UV exposure degrade Buna-N compounds over time.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 918\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.355 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.587 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.116 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\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: ZMSCH70918\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721161834802,"sku":"ZMSCH70918","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b4c9af67995d21855dc53f0a973366d5.jpg?v=1788574554","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70918-o-ring-dash-918-nbr-100-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
