It measures 1-1\/16 inches inside diameter and 3\/32 inches thick, with a durometer rating of 70 Shore A. NBR compound provides reliable resistance to petroleum-based fluids, hydraulic oils, and fuels, making this O-ring a standard choice for sealing applications in HVAC, plumbing, and fluid-handling equipment. Licensed plumbers, HVAC technicians, and mechanical contractors install this type of O-ring as a static or dynamic seal in a wide range of service and repair tasks.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for use in residential and light commercial applications where an inch-series Dash 121 seal is specified. Typical installation scenarios include valve bodies, pump housings, fittings, and refrigeration service ports where a reliable low-pressure to medium-pressure fluid seal is required. The NBR material performs across a broad service temperature range, making it appropriate for both chilled-water and hot-water system components as well as general plumbing repair.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDash 121 inch-series sizing — 1-1\/16 inches inside diameter, 3\/32 inches thick\u003c\/li\u003e\n\u003cli\u003eNitrile Butadiene Rubber (NBR) construction for resistance to petroleum-based fluids and hydraulic oils\u003c\/li\u003e\n\u003cli\u003eRound cross section for consistent sealing contact and reliable compression\u003c\/li\u003e\n\u003cli\u003e70 Shore A durometer for firm yet flexible sealing performance\u003c\/li\u003e\n\u003cli\u003eInch system of measurement for direct compatibility with standard inch-series hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard inch-series Dash 121 O-ring replacement for valves, fittings, pump housings, and other fluid-handling components that specify a 1-1\/16 inch ID, 3\/32 inch thick NBR seal.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber, HVAC technician, or qualified mechanic. Always depressurize and isolate the system before removing or replacing O-rings. Inspect the seating groove for damage or debris before installing the new O-ring. Applying a light coat of compatible lubricant to the O-ring before installation helps prevent tearing and ensures proper seating.\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: 121\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1-1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/32 inches\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 Shore A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\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--9988-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701563359538,"sku":"BDNA--9988-2","price":15.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d836e1f4d190fcd5ce0647731e72348b.jpg?v=1788401596","url":"https:\/\/voomisupply.com\/products\/value-collection-bdna-9988-2-o-ring-dash-121-nbr","provider":"Voomi Supply","version":"1.0","type":"link"}
