Built to a 5-inch by 4-inch by 4-inch configuration, this fitting splits or combines airflow between three duct legs while maintaining a sealed, corrosion-resistant connection. The hot-dip galvanizing process coats the steel inside and out, making it suitable for exhaust, combustion vent, and general air distribution applications. HVAC sheet metal mechanics and installers use this fitting in both new construction and retrofit duct work where a reliable wye branch is required.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for residential and light commercial duct systems where round pipe branches off a main trunk or where two branch runs merge into a single outlet. Typical applications include supply and return air distribution, combustion flue venting, and draft-hood connector runs. It is fabricated to meet ACCA and SMACNA standards, which are the primary industry references governing sheet metal duct construction and installation. The 5-inch main with dual 4-inch branches covers a common size pairing found in forced-air furnace and air handler installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot-dip galvanized steel construction for corrosion resistance in duct and flue applications\u003c\/li\u003e\n  \u003cli\u003e5-inch by 4-inch by 4-inch wye configuration for branching or combining round duct runs\u003c\/li\u003e\n  \u003cli\u003eFabricated to ACCA and SMACNA applicable standards\u003c\/li\u003e\n  \u003cli\u003eSheet metal construction suitable for combustion vent and general HVAC air distribution\u003c\/li\u003e\n  \u003cli\u003eThree-leg wye geometry allows airflow splitting or merging without sharp directional loss\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sheet metal wye fitting for round duct and flue pipe systems requiring a 5-inch main outlet and dual 4-inch branch connections, conforming to ACCA and SMACNA construction standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified sheet metal mechanic in accordance with SMACNA duct construction standards and any applicable local mechanical codes. Shut down the air handling equipment and, where flue or combustion vent service is involved, confirm the appliance is off and cooled before disturbing any duct connections. Secure joints with sheet metal screws and listed duct sealant or UL 181-listed tape as required by the application and local authority. Do not use this fitting beyond its rated duct or flue application without verifying local code acceptance.\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 Size\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBranch Size\u003c\/strong\u003e: 4 inches x 4 inches\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_5X4X4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284104085810,"sku":"52_5X4X4","price":21.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277032.jpg?v=1781068634","url":"https:\/\/voomisupply.com\/products\/southwark-metal-52_5x4x4-flue-wye-5x4x4-in-sheet-metal","provider":"Voomi Supply","version":"1.0","type":"link"}
