Manufactured from Nitrile Butadiene Rubber (Buna-N), this O-ring features a round cross-section profile suited for static and dynamic sealing applications in fluid and pneumatic systems. Buna-N material provides reliable resistance to petroleum-based fluids, making it a common choice in HVAC, plumbing, and general mechanical assemblies. Licensed trades and maintenance technicians install this type of seal during equipment servicing, valve repair, and fitting replacement work.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is appropriate for use in residential and light commercial applications wherever a Dash 211 size seal is specified. Typical install scenarios include pump and valve rebuilds, refrigeration service fittings, hydraulic connections, and plumbing shut-off assemblies. Its Buna-N compound is compatible with water, oils, and many common refrigerants in low-exposure sealing points. Always verify the specific fluid and temperature compatibility of Buna-N against the system medium before installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDash 211 standard sizing — 13\/16-inch inner diameter with 1\/8-inch cross-section thickness\u003c\/li\u003e\n  \u003cli\u003eNitrile Butadiene Rubber (Buna-N) construction for resistance to petroleum-based fluids and water\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 — suitable for high-volume service kit stocking\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 Dash 211 O-ring replacement for any application calling for a 13\/16-inch ID, 1\/8-inch thick Buna-N round cross-section seal in fluid or pneumatic systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers, HVAC technicians, or qualified maintenance mechanics. Always depressurize and isolate the system before removing or installing O-rings, and ensure all mating surfaces are clean and free of debris or old sealant. Lightly lubricating the O-ring with a compatible fluid or O-ring lubricant before installation helps prevent tearing during assembly. Do not stretch the O-ring beyond the groove dimensions, and inspect for nicks or cuts before seating.\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: 211\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross-Section Thickness\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-MP9986\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715187769650,"sku":"BDNA-MP9986","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9d8384c3e8bd0f5376a76d59e67ba4e_5dcc16a3-2c54-4862-bf82-6e4bdf1e5a56.jpg?v=1788510301","url":"https:\/\/voomisupply.com\/products\/value-collection-bdna-mp9986-o-ring-dash-211-nitrile-buna-n","provider":"Voomi Supply","version":"1.0","type":"link"}
