It measures 16 inches inner diameter by 21 inches outer diameter with a 2.5-inch cross-section thickness. NBR, also known as Buna-N, provides reliable resistance to petroleum-based fluids, hydraulic oils, and water, making it a standard sealing material across industrial and fluid-handling applications. Licensed plumbers, pipefitters, and industrial maintenance technicians typically install o-rings of this size during equipment assembly or preventive maintenance on large-bore valves, pumps, and fluid system components.\u003c\/p\u003e\n\u003cp\u003eThis o-ring is suited for static sealing applications on large-diameter flanges, pipe couplings, valve bonnets, pump housings, and similar industrial or commercial fluid-handling assemblies. Its Buna-N compound performs across a broad temperature range and holds up in contact with common shop fluids, lubricants, and water-based solutions. The round cross-section geometry seats evenly in standard o-ring grooves and does not require special tooling for installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e16 inch inner diameter and 21 inch outer diameter for large-bore sealing applications\u003c\/li\u003e\n  \u003cli\u003e2.5 inch cross-section thickness provides substantial sealing surface contact\u003c\/li\u003e\n  \u003cli\u003eNitrile Butadiene Rubber (Buna-N) material resists petroleum-based fluids, hydraulic oils, and water\u003c\/li\u003e\n  \u003cli\u003eRound cross-section geometry seats evenly in standard machined or molded o-ring grooves\u003c\/li\u003e\n  \u003cli\u003eUNSPSC code 31401503 for procurement and catalog system alignment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension replacement or service o-ring for large-bore industrial valves, pump housings, flanged couplings, and fluid-system components that accept a 16 inch ID by 21 inch OD round-cross-section NBR o-ring.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers, pipefitters, or industrial maintenance technicians. Always depressurize and drain the system before removing the old o-ring or installing a new one. Clean the mating groove thoroughly and inspect for nicks, burrs, or corrosion that could compromise the seal. Apply a compatible, fluid-rated lubricant to the o-ring before seating to prevent tearing during assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 21 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross-Section Thickness\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross-Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nitrile Butadiene Rubber (Buna-N)\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\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: BDNA-9336\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709353722162,"sku":"BDNA-9336","price":63.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9d8384c3e8bd0f5376a76d59e67ba4e_0bf7f0c2-630d-40e8-a167-a79fe107dafe.jpg?v=1788455103","url":"https:\/\/voomisupply.com\/products\/value-collection-bdna-9336-o-ring-16in-id-21in-od-nbr","provider":"Voomi Supply","version":"1.0","type":"link"}
