Constructed from hot dipped galvanized steel, it measures 7 inches by 4 inches by 3 inches and provides a durable, corrosion-resistant connection point within supply or return duct runs. This fitting meets ACCA and SMACNA standards, making it a code-appropriate choice for sheet metal duct installations. HVAC technicians and sheet metal installers use this wye to branch duct runs cleanly while maintaining system airflow balance.\u003c\/p\u003e\n\u003cp\u003eThis wye tee joint is suited for residential forced-air heating and cooling systems as well as light commercial ductwork where round duct configurations are used. It is typically installed at branch take-offs in supply trunk runs, allowing one main duct to split into two outlet paths. The 7-inch main with 4-inch and 3-inch branches accommodates common residential duct sizing scenarios where balanced distribution across multiple zones or rooms is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot dipped galvanized steel construction resists corrosion in conditioned air environments\u003c\/li\u003e\n  \u003cli\u003eRound profile compatible with standard round duct fittings and collars\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards for sheet metal duct fabrication\u003c\/li\u003e\n  \u003cli\u003eThree-port wye geometry supports clean branch take-offs with reduced turbulence versus sharp tee fittings\u003c\/li\u003e\n  \u003cli\u003e7 x 4 x 3 inch sizing fits common residential supply duct branch configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sheet metal fitting compatible with standard round duct systems built to ACCA and SMACNA guidelines.

Shut down the air handler or furnace and verify the system is de-energized before making any duct modifications. Secure the fitting with sheet metal screws and seal all joints with UL 181-listed foil tape or mastic sealant to prevent air leakage. Do not use this fitting in flue gas exhaust applications that carry combustion byproducts unless the system is specifically designed and rated for that service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dipped Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 7 inches x 4 inches x 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Round\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: 52_7X4X3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284020953394,"sku":"52_7X4X3","price":36.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277068.jpg?v=1781066286","url":"https:\/\/voomisupply.com\/products\/southwark-metal-52_7x4x3-duct-flue-wye-tee-7x4x3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
