This flexible elastomeric cord is used to fabricate custom O-rings, gaskets, and seals on the job or in a shop setting. At 0.25 inches in diameter with a tolerance of plus or minus 0.010 inches, it offers consistent sizing for reliable sealing applications. The material is rated for use down to -40 degrees F, making it suitable for cold-climate service environments. HVAC technicians, plumbers, and industrial maintenance trades commonly cut and join this cord stock to create seals where standard O-ring sizes are unavailable.\u003c\/p\u003e\n\u003cp\u003eBuna-N cord stock is a standard material choice for sealing applications involving petroleum-based fluids, oils, fuels, and many refrigerants. It is commonly used in HVAC equipment, plumbing assemblies, hydraulic systems, and general industrial maintenance. The round cross-section allows it to seat properly in standard O-ring grooves. This 100-foot coil provides enough material for multiple fabricated seals or replacement gaskets across a range of equipment types encountered in residential and light commercial service work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (nitrile rubber) material resists petroleum-based oils, fuels, and many common refrigerants\u003c\/li\u003e\n  \u003cli\u003e0.25 inch diameter with a tight tolerance of plus or minus 0.010 inches for consistent groove fit\u003c\/li\u003e\n  \u003cli\u003e100-foot coil length provides ample material for multiple custom seals or gaskets\u003c\/li\u003e\n  \u003cli\u003eRated to -40 degrees F minimum temperature for cold-climate and low-temperature service\u003c\/li\u003e\n  \u003cli\u003eRound cross-section seats correctly in standard O-ring grooves without modification\u003c\/li\u003e\n  \u003cli\u003eCut-to-length format allows fabrication of custom O-ring sizes not available as stock parts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for general use as a cut-to-length sealing cord in HVAC, plumbing, hydraulic, and industrial maintenance applications where a 0.25 inch diameter Buna-N round cord is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCut cord stock to the required length using a sharp, clean blade to ensure a square, burr-free end. When joining cut ends to form a custom O-ring, use a compatible nitrile bonding cement and allow full cure time before pressurizing the assembly. Depressurize and de-energize any system before replacing seals or gaskets. Verify chemical compatibility between the Buna-N material and the specific fluid or refrigerant in the system before installation.\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\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: plus or minus 0.010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoil Length\u003c\/strong\u003e: 100 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -40 degrees F\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: 5 pounds\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: 0284250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696763568434,"sku":"0284250","price":42.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b69acac216228b93f6d9ee005e2791e3.jpg?v=1788345989","url":"https:\/\/voomisupply.com\/products\/value-collection-0284250-buna-n-round-cord-stock-1-4-in-100-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
