Southwark Metal 52_5X4X3 Galvanized Flue Wye 5x4x3

Product Description

The SOUTHWARK METAL 52_5X4X3 is a hot dip galvanized steel sheet metal flue wye fitting used to create branch connections in round pipe duct and flue systems. Built to a 5-inch by 4-inch by 3-inch configuration, this wye transitions a main run into a single branch offset at an angle, allowing airflow or flue gas to be divided without sharp turns or pressure loss. The hot dip galvanized steel construction provides corrosion resistance suited for both duct and venting applications. HVAC sheet metal installers and mechanical contractors use this fitting on new construction and retrofit jobs where a tee-style branch is required in a round pipe system.

This wye fitting is designed for use in residential and light commercial HVAC duct systems and sheet metal flue pipe assemblies. It is suited for applications where a 5-inch main inlet branches to a 4-inch outlet and a 3-inch branch outlet. Typical install scenarios include trunk-and-branch supply duct layouts and gravity or induced-draft flue venting systems. Fabrication and installation practices follow ACCA and SMACNA standards, making this fitting appropriate for code-compliant mechanical work in both new construction and service applications.

Key Features

• Hot dip galvanized steel construction resists corrosion in duct and flue environments
• 5-inch by 4-inch by 3-inch size handles a main-to-branch reduction in a single fitting
• Wye geometry reduces turbulence compared to sharp tee branch connections
• Fabricated to ACCA and SMACNA applicable standards for commercial and residential mechanical systems
• Sheet metal construction compatible with standard drive and S-slip or mechanical fastener assembly methods

Compatibility

Designed as an OEM-style sheet metal branch fitting for round pipe duct and flue systems requiring a 5-inch inlet, 4-inch main outlet, and 3-inch branch outlet connection in ACCA- and SMACNA-compliant installations.

Installation Notes

Installation should be performed by a licensed sheet metal mechanic or HVAC technician in accordance with SMACNA duct construction standards and applicable local mechanical codes. Shut down the air handling system or disconnect power before making connections in an active duct system, and cap or seal all flue connections before relighting any connected appliance. Secure all joints with appropriate fasteners and seal with duct-rated mastic or foil tape as required by the system design. When used in flue applications, verify that the fitting material and gauge are rated for the flue gas temperature of the connected appliance.
