Buna-N is a widely specified elastomer for hydraulic, pneumatic, and fluid-handling applications due to its resistance to petroleum-based oils, fuels, and common refrigerants. This O-ring is used to create reliable static or dynamic seals in fittings, valves, pumps, and connectors across HVAC, plumbing, and general mechanical service work. Licensed tradespeople and experienced service technicians stock Dash 212 O-rings as a standard replacement seal size.\u003c\/p\u003e\n\u003cp\u003eThis O-ring fits applications requiring a Dash 212 standard size seal. Common use cases include refrigeration service port fittings, hydraulic line connections, pump housings, and plumbing valve seats where a 7\/8 inch ID Buna-N O-ring is called out. The round cross-section ensures consistent seating in standard O-ring grooves machined to AS568 Dash 212 dimensions. Suitable for residential and light commercial mechanical systems. Sold individually with a minimum order quantity of 10 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDash 212 standard sizing — 7\/8 inch inside diameter, 1\/8 inch cross-section thickness\u003c\/li\u003e\n  \u003cli\u003eNitrile Butadiene Rubber (Buna-N) construction resists petroleum-based oils, fuels, and many refrigerants\u003c\/li\u003e\n  \u003cli\u003eRound cross-section profile for consistent seating in standard O-ring grooves\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.01 pounds — easy to stock in field service kits\u003c\/li\u003e\n  \u003cli\u003eUNSPSC Code 31401503 for streamlined procurement classification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement O-ring for any application specifying an AS568 Dash 212 size seal in Nitrile Butadiene Rubber (Buna-N) material, including hydraulic fittings, pneumatic components, pump housings, and fluid-handling valves.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eO-ring replacement is performed by HVAC technicians, plumbers, and mechanical service professionals. Before replacing, depressurize and isolate the system and remove any residual fluid from the fitting or housing. Inspect the O-ring groove for nicks, burrs, or corrosion that could damage the new seal. Lightly lubricate the O-ring with a compatible lubricant before seating to prevent tearing during assembly — avoid petroleum-based greases on applications where compatibility is not confirmed.\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: 212\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness (Cross Section)\u003c\/strong\u003e: 1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: BDNA-MP9987\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689155559730,"sku":"BDNA-MP9987","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9d8384c3e8bd0f5376a76d59e67ba4e.jpg?v=1788255295","url":"https:\/\/voomisupply.com\/products\/value-collection-bdna-mp9987-o-ring-dash-212-nitrile","provider":"Voomi Supply","version":"1.0","type":"link"}
