Rated at 70 Shore A durometer, this O-ring delivers the firm, reliable sealing performance that HVAC, plumbing, and fluid-system technicians depend on. Operating temperature range spans -40 degrees F to 250 degrees F. Buna-N is the most widely used O-ring elastomer in the trade, valued for its excellent resistance to petroleum-based fluids and its strong compression set recovery. Each package contains 100 O-rings.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for static and dynamic sealing applications in residential and commercial systems where exposure to petroleum products, hydraulic fluids, oils, and fuels is expected. Typical applications include valves, fittings, pumps, compressors, and fluid-handling assemblies. It is appropriate for use in HVAC refrigerant service fittings, plumbing shutoff valves, and pool equipment where a Dash 011 nitrile seal is specified. The black Buna-N compound is not recommended for use with ozone-generating equipment, strong UV exposure, or non-petroleum-compatible media such as brake fluid or ketones.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBuna-N nitrile elastomer  -  the most common O-ring material in plumbing, HVAC, and fluid-system service\u003c\/li\u003e\n\u003cli\u003e70 Shore A durometer hardness rated Hard for firm compression and reliable sealing\u003c\/li\u003e\n\u003cli\u003eOperating range of -40 degrees F to 250 degrees F covers most mechanical and HVAC service conditions\u003c\/li\u003e\n\u003cli\u003eExcellent resistance to petroleum products, oils, and hydraulic fluids\u003c\/li\u003e\n\u003cli\u003eRound cross section with consistent 0.0625-inch thickness for uniform gland fit\u003c\/li\u003e\n\u003cli\u003eConforms to ASTM 568 dimensional standards\u003c\/li\u003e\n\u003cli\u003ePackage of 100 units supports shop stock and field service kits\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in applications requiring a Dash 011 nitrile O-ring compatible with petroleum products.

Shut off and relieve all pressure from the system before removing or replacing seals. Lightly lubricate the O-ring with a compatible petroleum-based or silicone grease before installation to ease seating and prevent tearing during assembly. Do not store Buna-N O-rings near motors, electrical equipment, or in direct sunlight, as ozone and UV exposure degrade the elastomer 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)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 011\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.301 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.441 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0625 inches (1\/16 inch)\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: Hard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\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\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASTM 568\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: 0.1 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: USA INDUSTRIALS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ZUSAH70011\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"USA INDUSTRIALS","offers":[{"title":"Default Title","offer_id":51972140794162,"sku":"ZUSAH70011","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/501ed35b0db9b2d3157af84abc1732d6.jpg?v=1789963344","url":"https:\/\/voomisupply.com\/products\/usa-industrials-zusah70011-nitrile-o-ring-dash-011-70-duro","provider":"Voomi Supply","version":"1.0","type":"link"}
