It measures 1-1\/4 inches inside diameter and 1\/8 inch thick. Buna-N is a standard elastomer choice for hydraulic, pneumatic, and fluid-handling applications where resistance to petroleum-based oils, fuels, and water is required. This O-ring is used as a static or dynamic face seal or radial seal and is sized to the Dash 218 standard, making it straightforward to cross-reference and replace in the field. Plumbers, HVAC technicians, and industrial maintenance professionals commonly stock Dash 218 rings for routine seal replacement tasks.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for residential and light commercial plumbing, HVAC refrigerant-side connections, hydraulic fittings, and general industrial fluid systems where a 1-1\/4 inch ID seal is required. Its Buna-N construction performs well across a broad range of petroleum oils, water, and many glycol-based fluids. It is not recommended for use with ketones, esters, or strong oxidizing acids. This item is sold individually with a minimum order quantity of 10 units, making it practical for service kits or bulk restocking.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDash 218 standard sizing for easy cross-reference and field replacement\u003c\/li\u003e\n\u003cli\u003e1-1\/4 inch inside diameter with 1\/8 inch cross-section thickness\u003c\/li\u003e\n\u003cli\u003eBuna-N (Nitrile Butadiene Rubber) material resists petroleum oils, fuels, and water\u003c\/li\u003e\n\u003cli\u003eRound cross section for consistent sealing performance in standard grooves\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.01 pounds per unit, suitable for kit and bulk stocking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 218 replacement O-ring for plumbing, HVAC, hydraulic, and pneumatic fittings and assemblies that require a 1-1\/4 inch ID, 1\/8 inch thick Buna-N seal.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber, HVAC technician, or qualified maintenance professional. Always depressurize and de-energize the system and drain any fluid from the line before removing the old seal. Inspect the groove for nicks, burrs, or corrosion before seating the new O-ring. Apply a compatible lubricant to the O-ring prior to installation to reduce the risk of tearing during assembly.\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: 218\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness (Cross Section)\u003c\/strong\u003e: 1\/8 inch\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\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-MP9991-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51707649032498,"sku":"BDNA-MP9991-2","price":16.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9d8384c3e8bd0f5376a76d59e67ba4e_7cb92d55-30e0-49a2-82c7-a76a21d0c9ef.jpg?v=1788441426","url":"https:\/\/voomisupply.com\/products\/value-collection-bdna-mp9991-2-o-ring-dash-218-nbr","provider":"Voomi Supply","version":"1.0","type":"link"}
