It measures 33 inches inside diameter, 39 inches outside diameter, and 3 inches thick. NBR is a synthetic elastomer widely specified for applications involving petroleum-based fluids, hydraulic oils, water, and moderate-temperature service. This O-ring is suited for static or dynamic sealing in large-bore assemblies across plumbing, hydraulic, industrial, and mechanical systems. Installation is typically performed by licensed plumbers, pipefitters, or millwrights during maintenance, repair, or new construction of equipment requiring large-diameter face or radial seals.\u003c\/p\u003e\u003cp\u003eThis O-ring is applicable in large-diameter sealing situations such as pipe flanges, valve bonnets, pump housings, tank lids, and similar assemblies where a 33-inch bore is present. NBR material makes it compatible with water, many petroleum-based fluids, and hydraulic media in systems operating at typical service pressures and temperatures within the material's rated range. It is sold individually with a minimum order quantity of 25 units, making it appropriate for stocking by maintenance operations or contractors managing recurring seal replacement programs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e33 inch inside diameter and 39 inch outside diameter provide precise large-bore fitment\u003c\/li\u003e\n\u003cli\u003e3 inch cross-section thickness for substantial sealing surface contact\u003c\/li\u003e\n\u003cli\u003eRound cross-section geometry for consistent radial compression in grooved seats\u003c\/li\u003e\n\u003cli\u003eNitrile Butadiene Rubber construction offers resistance to petroleum-based fluids and water\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.01 pounds per unit, minimizing shipping weight for bulk orders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement or maintenance O-ring for large-bore sealing assemblies requiring a 33-inch ID, 39-inch OD, 3-inch thick NBR round-cross-section seal.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDepressurize and isolate the system completely before removing the existing seal or disassembling any flanged joint. Inspect the sealing groove for nicks, corrosion, or debris that could compromise the new seal's integrity. Lubricate the O-ring with a fluid compatible with both the elastomer and the system media before seating to prevent tearing during assembly. Installations involving pressurized piping or mechanical equipment should follow applicable codes such as ASME B31 or relevant local standards.\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\u003eInside Diameter\u003c\/strong\u003e: 33 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\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\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-9373\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716181393714,"sku":"BDNA-9373","price":51.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/449d8273b8aa751b5898816bcacaa168.jpg?v=1788522839","url":"https:\/\/voomisupply.com\/products\/value-collection-bdna-9373-o-ring-nbr-33x39x3-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
