It measures 0.986 inches inside diameter, 1.218 inches outside diameter, and 0.116 inches thick, with a round cross-section profile. Rated at 70 Shore A hardness, this O-ring delivers reliable compression set resistance along with strong tear and abrasion resistance. It is compatible with petroleum-based fluids and operates across a temperature range of -40 degrees F to 250 degrees F. Licensed plumbers, HVAC technicians, and hydraulic system technicians regularly specify Buna-N O-rings for these performance characteristics.\u003c\/p\u003e\u003cp\u003eThis O-ring functions as an O-Ring Boss (ORB) gasket for straight-thread tube fittings, making it suitable for hydraulic lines, pneumatic assemblies, plumbing connections, and HVAC refrigerant circuit components where a petroleum-compatible seal is required. It is appropriate for both residential and light commercial applications. The Dash 913 designation follows standard AS568 sizing, allowing straightforward cross-referencing with OEM fitting specifications. Each package contains 100 O-rings, supporting fleet service operations and shops that require consistent on-hand inventory.\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-fluid compatibility\u003c\/li\u003e\n\u003cli\u003e70 Shore A hardness with round cross-section for reliable static and dynamic sealing\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of -40 degrees F to 250 degrees F\u003c\/li\u003e\n\u003cli\u003eFunctions as an O-Ring Boss gasket for straight-thread tube fittings\u003c\/li\u003e\n\u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n\u003cli\u003ePackaged in quantities of 100 for shop and fleet use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with petroleum products and compatible fluids in hydraulic, pneumatic, and fluid-handling systems that accept a Dash 913 ORB gasket for straight-thread tube fittings.

Depressurize and drain the system before removing any fittings or seals. Lightly lubricate the O-ring with a compatible fluid prior to installation to prevent tearing during assembly. Do not store unused O-rings in direct sunlight or near motors and electrical equipment that may generate ozone, as ozone exposure degrades Buna-N elastomers.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.986 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.218 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.116 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 913\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross-Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Buna-N (Nitrile Butadiene Rubber)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\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 Fluids\u003c\/strong\u003e: Petroleum products\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: O-Ring Boss gasket for straight-thread tube fittings\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\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: ZMSCH70913\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51707802059058,"sku":"ZMSCH70913","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_80a50409-3bb1-4ace-b12e-c1c7535ca68d.jpg?v=1788442253","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70913-o-ring-dash-913-nbr-70","provider":"Voomi Supply","version":"1.0","type":"link"}
