Constructed from Nitrile Butadiene Rubber (Buna-N), it measures 1-1\/8 inches inside diameter with a 1\/8 inch cross-section thickness and a round cross-section profile. Buna-N compound provides solid resistance to petroleum-based oils, fuels, and hydraulic fluids, making this O-ring a dependable choice for plumbing, HVAC, and general mechanical assemblies. Plumbers, HVAC technicians, and maintenance mechanics typically specify Dash 216 O-rings for valve bodies, fittings, pump housings, and refrigeration service ports where a reliable face or radial seal is required.\u003c\/p\u003e\u003cp\u003eThis O-ring fits standard Dash 216 groove applications across residential and light commercial systems. Common installation scenarios include replacement seals in ball valves, solenoid valves, refrigerant service fittings, and hydraulic quick-connect couplings. The Buna-N material is well suited for systems carrying water, mineral oil-based hydraulic fluid, or refrigeration oils compatible with NBR elastomers. This part is sold individually with a minimum order quantity of 25 units, making it appropriate for stocking in a service truck or shop inventory.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDash 216 standard sizing for direct drop-in fit in groove-specified assemblies\u003c\/li\u003e\n\u003cli\u003eBuna-N (Nitrile Butadiene Rubber) compound resists petroleum oils, hydraulic fluids, and water\u003c\/li\u003e\n\u003cli\u003e1-1\/8 inches inside diameter with 1\/8 inch cross-section thickness\u003c\/li\u003e\n\u003cli\u003eRound cross-section profile for consistent sealing contact and groove retention\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.01 pounds, suitable for high-volume service stocking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service seal for any application calling out a standard Dash 216 O-ring groove specification in plumbing, HVAC, pool, or general mechanical equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified plumber, HVAC technician, or mechanical tradesperson familiar with O-ring seal service. Always depressurize and de-energize the system and drain any residual fluid before removing the old seal. Lightly lubricate the O-ring with a compatible grease or fluid prior to installation to prevent tearing during assembly; never use a petroleum lubricant on an elastomer that may not be chemically compatible. Inspect the groove and mating surfaces for nicks or corrosion before seating the new ring.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 216\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1-1\/8 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: 25\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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BDNA-9991\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689402171698,"sku":"BDNA-9991","price":21.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9d8384c3e8bd0f5376a76d59e67ba4e_4794a96e-a716-44f0-95ef-a5832e3f369e.jpg?v=1788258901","url":"https:\/\/voomisupply.com\/products\/value-collection-bdna-9991-o-ring-dash-216-nitrile-rubber","provider":"Voomi Supply","version":"1.0","type":"link"}
