It measures 2.1875 inches inner diameter, 2.38 inches outer diameter, and 0.0937 inches thick, with a round cross section. Rated to a hardness of 70 Shore A, this O-ring maintains its sealing integrity across a wide temperature range. HVAC technicians, plumbers, and mechanical contractors use NBR O-rings like this in hydraulic circuits, refrigerant-side fittings, water lines, and pneumatic assemblies where oil and petroleum fluid resistance is required.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for residential and commercial applications involving oil, fuel, water, and many hydraulic fluids. It performs reliably in systems where operating temperatures fall between -40 degrees F and 275 degrees F. Common installation scenarios include pump housings, valve bodies, pipe unions, manifold ports, and compressor fittings. It is sold individually, with a minimum order quantity of 25 units, making it appropriate for service fleets and shop stock replenishment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNBR material offers strong resistance to petroleum-based oils, fuels, and hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003eWide service temperature range: -40 degrees F to 275 degrees F\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness rating suits both static and dynamic sealing applications\u003c\/li\u003e\n  \u003cli\u003eRound cross section for consistent groove seating and predictable compression\u003c\/li\u003e\n  \u003cli\u003eDash 139 standard sizing ensures drop-in fitment in compatible grooves\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.01 pounds per unit, practical for bulk stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 139 replacement O-ring for use in any groove machined to AS568 Dash 139 dimensions accepting a 2.1875-inch ID NBR seal.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eO-ring installation should be performed by a qualified technician after fully depressurizing and de-energizing the system. Inspect the groove for burrs, scoring, or contamination before seating the new O-ring. Apply a compatible lubricant to the O-ring prior to installation to prevent tearing during assembly. Avoid rolling or twisting the O-ring into the groove, as this introduces stress and reduces service life.\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 (NBR)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 139\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.38 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0937 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 70 Shore A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: Hard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 275 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Package 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\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: ZBD9984-17\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709709189426,"sku":"ZBD9984-17","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9d8384c3e8bd0f5376a76d59e67ba4e_9b4ce1a1-f41b-4eef-83a6-ab96c9a957c3.jpg?v=1788459408","url":"https:\/\/voomisupply.com\/products\/value-collection-zbd9984-17-o-ring-dash-139-nbr","provider":"Voomi Supply","version":"1.0","type":"link"}
