With a 0.706-inch inside diameter, 0.900-inch outside diameter, and a 0.097-inch thick round cross section, this O-ring is sized to the SAE Dash 909 standard. It carries a Shore A hardness of 70, placing it in the hard rating category. The Buna-N compound delivers excellent resistance to petroleum-based fluids, strong compression set performance, and solid tear and abrasion resistance. Licensed plumbers, HVAC technicians, and hydraulic system technicians rely on this O-ring for reliable static and dynamic sealing in fuel, oil, and hydraulic circuits.\u003c\/p\u003e\u003cp\u003eThis O-ring is intended for use as an O-ring boss gasket on straight-thread tube fittings, a common connection style in HVAC refrigerant lines, hydraulic assemblies, and plumbing supply systems. It is compatible with petroleum-based products including oils, fuels, and hydraulic fluids. The operating temperature range spans -40 degrees F to 250 degrees F, making it suitable for both standard HVAC service and light industrial applications. This listing covers a package quantity of 100 O-rings, appropriate for shop stock or multi-unit service calls. Store away from direct sunlight, ozone sources, and electrical equipment that may generate ozone.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBuna-N (Nitrile Butadiene Rubber) construction with excellent petroleum product resistance\u003c\/li\u003e\n\u003cli\u003eDash 909 standard sizing: 0.706 inches ID, 0.900 inches OD, 0.097 inches thick\u003c\/li\u003e\n\u003cli\u003eRound cross section, Shore A hardness of 70 (hard rating)\u003c\/li\u003e\n\u003cli\u003eOperating range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n\u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n\u003cli\u003eSized as an O-ring boss gasket for straight-thread tube fittings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use as an O-ring boss gasket on straight-thread tube fittings in systems that use petroleum-based fluids, including HVAC, hydraulic, and plumbing applications.

Shut off system pressure and depressurize the line completely before replacing any O-ring. Lightly lubricate the O-ring with a compatible fluid or petroleum-based lubricant before seating to prevent pinching or tearing during assembly. Avoid storing unused O-rings near motors, ozone-generating 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: Buna-N (Nitrile Butadiene Rubber)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 909\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.706 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.900 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.097 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\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: ZMSCH70909\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689352364338,"sku":"ZMSCH70909","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a75c5f5084ae6b8a1bad939d1407db5.jpg?v=1788258084","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70909-o-ring-dash-909-nbr-100-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
