It splits a single main duct run into two branch legs, allowing installers to route conditioned air to multiple zones or terminal points. The main collar measures 9 inches with two 7-inch branch outlets. Hot dip galvanized construction resists corrosion in both residential and light commercial environments. This fitting is fabricated to ACCA and SMACNA standards, which means dimensional tolerances and metal gauges meet recognized industry benchmarks for HVAC sheet metal work. HVAC sheet metal mechanics and duct installers are the primary trade for this component.\u003c\/p\u003e\n\u003cp\u003eThis wye branch is suited for supply-side or return-side trunk-and-branch duct systems in residential and light commercial HVAC installations. It connects into round spiral or snap-lock galvanized duct runs where the main trunk steps from 9 inches to two 7-inch branch legs. Typical applications include forced-air furnace systems, central air handlers, and makeup air units where the distribution layout requires a symmetrical split. The fitting is installed at duct junctions during new construction or retrofit duct modification work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot dip galvanized steel construction for corrosion resistance in HVAC duct environments\u003c\/li\u003e\n  \u003cli\u003e9-inch main inlet with dual 7-inch branch outlets for symmetrical duct splitting\u003c\/li\u003e\n  \u003cli\u003eFabricated to ACCA and SMACNA applicable standards for dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard round galvanized duct pipe and fittings of matching diameter\u003c\/li\u003e\n  \u003cli\u003eSheet metal construction allows field modification with standard duct tools when needed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style duct fitting for use in round galvanized sheet metal duct systems requiring a 9-inch main to dual 7-inch branch wye configuration, built to ACCA and SMACNA standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis fitting is installed by licensed sheet metal mechanics or HVAC technicians following SMACNA duct construction standards and applicable local mechanical codes. Shut down the air handling unit and isolate the duct section before cutting into an existing trunk line. Connections should be secured with sheet metal screws and sealed with UL 181-listed duct tape or mastic sealant to prevent air leakage. Wear appropriate cut-resistant gloves when handling raw sheet metal edges.\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\u003eMain Inlet Size\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBranch Outlet Size\u003c\/strong\u003e: 7 inches (x2)\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: 78_9X7X7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283913736498,"sku":"78_9X7X7","price":33.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309276994.jpg?v=1781063118","url":"https:\/\/voomisupply.com\/products\/southwark-metal-78_9x7x7-sheet-metal-wye-branch-9x7x7","provider":"Voomi Supply","version":"1.0","type":"link"}
