Made from Nitrile Butadiene Rubber (Buna-N), this round cross-section O-ring measures 0.644 inches ID, 0.818 inches OD, and 0.087 inches thick. It carries a hardness rating of 70 Shore A, classifying it as hard. Rated for service from -40 degrees F to 250 degrees F, it is suited for applications where petroleum-based fluids are present. Licensed plumbers, HVAC technicians, and fluid-systems mechanics commonly use this O-ring as a sealing element in fitting assemblies.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is used in residential and commercial applications wherever Dash 908 boss gaskets are required at straight-thread ports and fittings. Typical install scenarios include hydraulic lines, refrigerant-side connections, fuel systems, and general plumbing fitting assemblies that contact petroleum products. It meets SAE and MIL-Spec standards, making it appropriate for both commercial mechanical work and maintenance applications requiring specification-grade sealing components. Sold in a package quantity of 100, it suits bench-stock and service-van replenishment needs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\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\u003eRated -40 degrees F to 250 degrees F continuous service temperature range\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness provides resistance to extrusion under pressure\u003c\/li\u003e\n  \u003cli\u003eExcellent compression set, tear resistance, and abrasion resistance for long seal life\u003c\/li\u003e\n  \u003cli\u003eRound cross-section profile conforms to standard O-ring boss port geometry\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an O-ring boss gasket for straight-thread tube fittings requiring a Dash 908 O-ring.

Depressurize and drain the system fully before replacing O-rings at any fitting. Lubricate the O-ring lightly with a compatible fluid or assembly lubricant before seating to prevent tearing during torque-up. Do not reuse O-rings that show signs of compression set, cracking, or surface damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 908\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.6440 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.8180 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0870 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 Fluids\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\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: ZMSCH70908\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702706078002,"sku":"ZMSCH70908","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b55b2070e5013c9ba03d638b6c742962.jpg?v=1788412880","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70908-o-ring-dash-908-nitrile","provider":"Voomi Supply","version":"1.0","type":"link"}
