Southwark Metal 52_4X3X3 Flue Wye Tee 4x3x3 in Galvanized

Product Description

The SOUTHWARK METAL 52_4X3X3 is a round sheet metal duct flue wye tee joint fabricated from hot-dipped galvanized steel. It provides a three-way branch connection in residential and light commercial duct and flue systems, splitting or combining airflow at a single junction point. The main inlet measures 4 inches with two 3-inch branch outlets, making it suitable for low-pressure air distribution runs. HVAC technicians and sheet metal installers use this fitting where a round duct run requires a wye-style branch takeoff. The galvanized steel construction resists corrosion in typical duct environments.

This wye tee joint is used in residential forced-air duct systems and flue applications where a round branch connection is required. It fits into standard round duct assemblies and is suited for supply or return branch runs that conform to ACCA and SMACNA duct construction standards. The fitting is appropriate for new construction duct layout and retrofit branch additions where a wye geometry is preferred over a straight tee for reduced turbulence and improved airflow distribution.

Key Features

• Hot-dipped galvanized steel construction provides corrosion resistance for duct and flue environments
• Round wye tee geometry supports smoother airflow transitions compared to sharp-angle fittings
• 4-inch main by dual 3-inch branch sizing covers common residential duct branch configurations
• Fabricated to ACCA and SMACNA applicable standards for duct system construction
• Ready for connection into standard round duct runs with conventional sheet metal fastening methods

Compatibility

Designed as an OEM-style replacement and new-install fitting for round sheet metal duct and flue systems conforming to ACCA and SMACNA construction standards.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal workers. Secure all duct connections with sheet metal screws and seal joints with listed duct sealant or mastic in accordance with SMACNA duct construction guidelines and applicable local mechanical codes. Verify that the main duct and branch duct diameters match the fitting dimensions before fastening. Ensure the system is fully de-energized and airflow is stopped before modifying any section of an active duct run.
