Constructed from hot-dipped galvanized steel, it provides corrosion resistance suitable for supply and return air applications. The fitting measures 14 inches on the main trunk with two 12-inch branch outlets. HVAC installers and sheet metal contractors use this type of wye branch when airflow must be divided at a junction point while maintaining round duct continuity throughout the system.\u003c\/p\u003e\n\u003cp\u003eThis wye branch fitting is suited for forced-air heating and cooling distribution systems where round ductwork is specified. It is a common component in new construction and retrofit installations that follow ACCA and SMACNA duct fabrication and performance standards. The 14-inch by 12-inch by 12-inch configuration handles trunk-to-branch transitions in systems where balanced airflow across two zones or outlets is required. Sheet metal contractors and HVAC mechanics install this fitting during rough-in or duct modification work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot-dipped galvanized steel construction for corrosion resistance in air distribution environments\u003c\/li\u003e\n  \u003cli\u003eRound duct configuration with 14-inch main and dual 12-inch branch outlets\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards for duct fittings\u003c\/li\u003e\n  \u003cli\u003eWye branch geometry supports balanced airflow splitting versus abrupt tee fittings\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard round spiral and snap-lock duct systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for round sheet metal duct systems requiring a 14-inch by 12-inch by 12-inch wye branch junction, fabricated to ACCA and SMACNA 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 contractor. Shut down the air handling unit and confirm the system is de-energized before cutting into or modifying existing ductwork. Seal all joints with UL 181-listed duct sealant or approved metal foil tape per local mechanical code requirements. Support the fitting independently per SMACNA hanger spacing guidelines to prevent stress on adjacent duct connections.\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\u003eType\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMain Size\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBranch Size\u003c\/strong\u003e: 12 inches x 12 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: 78_14X12X12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283910361394,"sku":"78_14X12X12","price":65.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309276993.jpg?v=1781063040","url":"https:\/\/voomisupply.com\/products\/southwark-metal-78_14x12x12-duct-wye-branch-14x12x12","provider":"Voomi Supply","version":"1.0","type":"link"}
