Fabricated from hot-dip galvanized steel, this cap delivers corrosion resistance suited for both conditioned and unconditioned space installations. The no-crimp design means the cap fits over the duct connection without a beaded crimp edge, which simplifies fitting to certain duct configurations. At 12 inches in diameter, it is sized for standard round duct tee branches commonly found in residential and light commercial forced-air distribution systems. Licensed HVAC technicians and sheet metal mechanics are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis tee end cap is used wherever a branch or end opening on a round duct tee must be sealed off permanently or temporarily during system installation, balancing, or modification. It is appropriate for residential forced-air heating and cooling duct systems as well as light commercial HVAC applications. The 12-inch diameter fits standard round duct tee outlets of the same nominal size. Installation typically occurs during rough-in duct work or system modifications where an active branch is no longer needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo-crimp design for straightforward installation on compatible tee fittings without a beaded edge\u003c\/li\u003e\n  \u003cli\u003eHot-dip galvanized steel construction provides corrosion resistance for long service life\u003c\/li\u003e\n  \u003cli\u003e12-inch nominal diameter fits standard round duct tee branch openings\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards for sheet metal duct fittings\u003c\/li\u003e\n  \u003cli\u003eSuitable for residential and light commercial forced-air HVAC duct systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sheet metal fitting for use with 12-inch nominal round duct tee fittings in residential and light commercial HVAC duct systems built to ACCA and SMACNA standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis fitting is installed by licensed HVAC technicians or qualified sheet metal mechanics. Power down the air handling unit and close all dampers before working on the duct system. Secure the cap to the tee opening using sheet metal screws and seal all joints with UL 181-rated foil tape or mastic sealant per SMACNA guidelines to prevent air leakage. Do not force the cap onto a beaded or crimped tee outlet for which it was not designed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dip Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 12 inches\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_12IN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284024557874,"sku":"55NC_12IN","price":20.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277437.jpg?v=1781066408","url":"https:\/\/voomisupply.com\/products\/southwark-metal-55nc_12in-duct-tee-end-cap-12-in-no-crimp","provider":"Voomi Supply","version":"1.0","type":"link"}
