Constructed from hot-dip galvanized steel, this cap fits a 14-inch diameter duct tee opening and provides a clean, secure termination without requiring a crimped edge for installation. It is manufactured to meet ACCA and SMACNA standards, making it appropriate for commercial and residential ductwork installations where compliant fabrication is required. HVAC sheet metal mechanics and duct installers are the primary trades that handle this fitting.\u003c\/p\u003e\n\u003cp\u003eThis end cap is used wherever a round duct tee branch needs to be capped off — common scenarios include balancing airflow by blocking an unused branch, sealing a tee during phased construction, or permanently closing off a branch that is no longer needed in the duct layout. The no-crimp design simplifies field installation and works with standard 14-inch round duct tee fittings found in both light commercial and residential forced-air systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo-crimp design eliminates the need for a crimped duct end, speeding up field installation\u003c\/li\u003e\n  \u003cli\u003eHot-dip galvanized steel construction provides corrosion resistance in occupied and unconditioned spaces\u003c\/li\u003e\n  \u003cli\u003e14-inch diameter fits standard round duct tee openings of the same size\u003c\/li\u003e\n  \u003cli\u003eManufactured to ACCA and SMACNA applicable standards for compliant ductwork assemblies\u003c\/li\u003e\n  \u003cli\u003ePlain end cap profile for straightforward termination of unused or sealed tee branches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-fit cap for 14-inch diameter round sheet metal duct tee fittings in forced-air HVAC duct systems built to ACCA and SMACNA fabrication standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed sheet metal mechanic or HVAC technician following SMACNA duct construction standards. The air handling system should be powered down and airflow stopped before capping or reconfiguring any duct branch. Secure the cap with sheet metal screws and seal all joints with UL 181-rated duct sealant or mastic as required by local mechanical codes. Do not use this cap on pressurized duct systems operating outside standard residential or light commercial static pressure ranges without verifying fitment with the duct system design.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dip Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: No Crimp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: ACCA, SMACNA\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: SOUTHWARK METAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 55NC_14IN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283966755122,"sku":"55NC_14IN","price":22.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277506.jpg?v=1781064473","url":"https:\/\/voomisupply.com\/products\/southwark-metal-55nc_14in-duct-tee-end-cap-14-in","provider":"Voomi Supply","version":"1.0","type":"link"}
