Duct takeoffs connect branch ducts to a main trunk line, allowing conditioned air to be distributed to individual zones or rooms within a forced-air system. This fitting is built to ACCA and SMACNA standards, making it a reliable choice for duct systems that require consistent airflow performance and structural integrity. HVAC installers and sheet metal contractors use this type of fitting in both new construction and retrofit applications where a tight, secure branch connection is required.\u003c\/p\u003e\u003cp\u003eThis takeoff is suited for residential and light commercial forced-air HVAC duct systems. The Air-Tite designation indicates the fitting is designed to reduce air leakage at the branch connection point, which supports duct system efficiency and helps meet building performance requirements. It is commonly installed on rectangular or round trunk ducts where an 8-inch branch run needs to be tapped in cleanly and securely.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-inch diameter sizing for standard branch duct connections\u003c\/li\u003e\n\u003cli\u003eHot dip galvanized steel construction for corrosion resistance and long service life\u003c\/li\u003e\n\u003cli\u003eAir-Tite design reduces air leakage at the takeoff connection\u003c\/li\u003e\n\u003cli\u003eMeets ACCA and SMACNA applicable standards for duct fabrication and performance\u003c\/li\u003e\n\u003cli\u003eCompatible with standard 8-inch round branch duct runs in forced-air systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 8-inch branch connections in residential and light commercial forced-air duct systems built to ACCA and SMACNA standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or journeyman sheet metal worker. The air handling system should be powered down and airflow stopped before cutting into the trunk duct or securing the takeoff fitting. Sheet metal screws and UL 181-rated duct tape or mastic sealant are commonly used to secure and seal the connection in compliance with local mechanical codes. Do not overtighten fasteners on the galvanized collar, as deformation can compromise the Air-Tite seal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 8 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: Air-Tite Duct Takeoff\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: ACCA, SMACNA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: ATT_8IN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284010565938,"sku":"ATT_8IN","price":16.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278203.jpg?v=1781065957","url":"https:\/\/voomisupply.com\/products\/southwark-metal-att_8in-duct-takeoff-8-inch-air-tite","provider":"Voomi Supply","version":"1.0","type":"link"}
