It measures 1-3\/4 inches inside diameter with a 1\/8 inch cross-section thickness and a round cross-section profile. Molded from Nitrile Butadiene Rubber (NBR) with a 70 durometer hardness rating, it offers reliable resistance to petroleum-based oils, fuels, and common hydraulic fluids. Licensed plumbers, HVAC technicians, and industrial maintenance professionals install these rings wherever a dependable inch-system seal is required.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for residential and commercial plumbing systems, HVAC refrigerant and fluid circuits, hydraulic equipment, and general industrial machinery. The Dash 224 designation follows the standard AS568 inch-series sizing system, making it straightforward to source as a direct replacement in any application calling out that dash number. Its NBR compound performs across a broad range of operating temperatures, making it a common choice in both fixed and moving-joint sealing scenarios.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDash 224 designation per standard inch-series O-ring sizing\u003c\/li\u003e\n\u003cli\u003e1-3\/4 inch inside diameter for precise fit in standard-sized grooves\u003c\/li\u003e\n\u003cli\u003e1\/8 inch round cross-section for consistent compression and seal integrity\u003c\/li\u003e\n\u003cli\u003eNitrile Butadiene Rubber (NBR) material resists petroleum oils, hydraulic fluids, and fuels\u003c\/li\u003e\n\u003cli\u003e70 durometer hardness balances flexibility with wear resistance\u003c\/li\u003e\n\u003cli\u003eInch measurement system for compatibility with standard SAE and imperial hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard inch-series replacement O-ring for any application specifying a Dash 224 size in NBR or equivalent nitrile compound.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified plumber, HVAC technician, or hydraulic systems technician. Relieve all system pressure and shut off fluid supply before removing the existing O-ring. Lightly lubricate the O-ring with a compatible fluid or grease before seating it in the groove to prevent tearing during assembly. Avoid using petroleum-based lubricants with non-NBR compounds and never stretch the ring beyond the groove diameter during installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nitrile Butadiene Rubber (NBR)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 224\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross-Section Thickness\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\u003eDurometer\u003c\/strong\u003e: 70\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement System\u003c\/strong\u003e: Inch\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\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--9991-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51719202406706,"sku":"BDNA--9991-8","price":26.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d76e84ae39ce3860d1d7e351f7769616.jpg?v=1788558095","url":"https:\/\/voomisupply.com\/products\/value-collection-bdna-9991-8-o-ring-dash-224-nbr","provider":"Voomi Supply","version":"1.0","type":"link"}
