Buna-N is a synthetic elastomer widely used in fluid-handling and sealing applications because of its strong resistance to petroleum-based oils, fuels, and hydraulic fluids. With a diameter of 7\/16 inch (0.4370 inches decimal), this cord stock is sized for fabricating custom O-rings, gaskets, and face seals on the job. Plumbers, HVAC technicians, and industrial maintenance professionals cut and splice this material to length for static and low-motion sealing tasks where a molded part is not available.\u003c\/p\u003e\n\u003cp\u003eThis round cord stock is used in residential and commercial plumbing, HVAC equipment, and general industrial maintenance wherever a field-fabricated seal is needed. Common applications include pump housings, valve bodies, pipe flanges, and manifold covers that see petroleum-based fluids or water. The 100-foot coil length provides enough material for multiple seal fabrications from a single stock unit, reducing the need for frequent reorder on active service trucks or in shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (nitrile) compound offers strong resistance to petroleum oils, fuels, and hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003e7\/16 inch (0.4370 inches) diameter for consistent cross-section in custom seal fabrication\u003c\/li\u003e\n  \u003cli\u003e100-foot coil length supports multiple field or shop fabrications per unit\u003c\/li\u003e\n  \u003cli\u003eRound cross-section seats cleanly in standard O-ring grooves and face-seal channels\u003c\/li\u003e\n  \u003cli\u003eInch measurement system for direct compatibility with standard U.S. groove specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a field-fabrication cord stock for static and low-motion sealing applications in plumbing, HVAC, and general industrial equipment that use 7\/16-inch-diameter round-profile seals in petroleum-oil or water service.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCut cord stock to the required circumference length using a sharp blade and a clean, square cut to ensure a tight splice joint. A cord cement or vulcanizing adhesive appropriate for nitrile rubber is typically used to join the cut ends when forming a closed-loop seal. Depressurize and drain the system and isolate all fluid sources before replacing any seal. Verify that the groove dimensions match the 0.4370-inch cord diameter before installation to maintain proper compression and sealing performance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Buna-N (Nitrile Rubber)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter (Fractional)\u003c\/strong\u003e: 7\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter (Decimal)\u003c\/strong\u003e: 0.4370 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoil Length\u003c\/strong\u003e: 100 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 0284437\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692176769330,"sku":"0284437","price":114.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ce2d1322413d6278ebb307a164b9a98.jpg?v=1788294146","url":"https:\/\/voomisupply.com\/products\/value-collection-0284437-buna-n-round-cord-stock-7-16-in-100-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
