It measures 1.75 inches inside diameter, 1.375 inches outside diameter, and 0.125 inches thick. The 70 durometer hardness rating makes it well suited for sealing applications that require moderate flexibility combined with resistance to petroleum-based fluids, hydraulic oils, and water. This O-ring is installed by plumbers, HVAC technicians, and pipefitters as a static or dynamic face seal in fluid-handling assemblies and mechanical joints.\u003c\/p\u003e\u003cp\u003eThis O-ring is appropriate for use in residential and light commercial plumbing systems, HVAC refrigerant circuits, hydraulic assemblies, and pool and spa equipment where a standard inch-series Dash 220 seal is required. Its NBR compound performs reliably across a broad temperature range, making it a practical replacement seal in pump housings, valve bodies, and threaded port connections.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDash 220 standard sizing ensures drop-in fitment with existing inch-series O-ring grooves\u003c\/li\u003e\n\u003cli\u003eNitrile Butadiene Rubber (NBR) compound resists petroleum-based oils, hydraulic fluids, and water\u003c\/li\u003e\n\u003cli\u003e70 durometer hardness balances flexibility with compression resistance for reliable sealing\u003c\/li\u003e\n\u003cli\u003eRound cross section provides consistent groove contact and uniform sealing pressure\u003c\/li\u003e\n\u003cli\u003eInch measurement system for compatibility with standard domestic hardware and fittings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for applications requiring a Dash 220 inch-series O-ring in plumbing, HVAC, hydraulic, and pool or spa equipment assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers, HVAC technicians, or qualified mechanical trades. Always depressurize and drain the system before removing existing seals. Inspect the O-ring groove for burrs or corrosion before seating the new O-ring, and apply a compatible lubricant to reduce the risk of tearing during assembly. Do not over-compress the O-ring during fastener tightening, as excess deformation will reduce service life.\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: 220\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 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\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\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--9991-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694335721778,"sku":"BDNA--9991-4","price":26.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/13eac2ac1957c58febea0618949eb852.jpg?v=1788323286","url":"https:\/\/voomisupply.com\/products\/value-collection-bdna-9991-4-o-ring-dash-220-nbr","provider":"Voomi Supply","version":"1.0","type":"link"}
