The SOUTHWARK METAL 52_5X5X3 is a round sheet metal duct flue wye tee joint used to split or branch airflow in HVAC duct and flue systems. Constructed from hot-dipped galvanized steel, it offers corrosion resistance suitable for residential and light commercial ductwork applications. The fitting measures 5 inches by 5 inches by 3 inches, providing a standard branch configuration for connecting main trunk lines to lateral runs. HVAC installers and sheet metal mechanics select this type of fitting when routing supply or flue distribution branches within a forced-air system.
This wye tee fitting is designed for use in round duct and flue systems where a main run must branch into a smaller lateral. The 5-inch by 5-inch by 3-inch sizing makes it a common choice for residential forced-air distribution systems and flue venting assemblies. It is typically installed by licensed HVAC technicians or sheet metal contractors working on new construction or retrofit duct systems.
Designed as an OEM-style replacement or new-installation fitting for round sheet metal duct and flue systems conforming to ACCA and SMACNA standards.
Installation should be performed by a qualified HVAC technician or licensed sheet metal contractor. Shut down the air handling system and isolate any connected flue or combustion appliance before beginning work. Secure the fitting with sheet metal screws and seal joints with UL-listed foil tape or mastic sealant per SMACNA guidelines. Follow all applicable local mechanical codes when routing or modifying flue duct assemblies.
