Southwark Metal 52_7X6X4 Sheet Metal Flue Wye 7x6x4

Product Description

The SOUTHWARK METAL 52_7X6X4 is a hot-dip galvanized steel sheet metal flue wye used to split or combine airflow in round duct and flue pipe systems. The tee-style wye configuration joins a 7-inch main run to a 6-inch and a 4-inch branch, making it a practical transition fitting for residential and light commercial ductwork. Fabricated from hot-dip galvanized steel, it resists corrosion in both heating flue and ventilation applications. HVAC sheet metal installers and plumbers use this fitting when routing B-vent, combustion exhaust, or supply duct branches from a common trunk line.

This wye fitting is suited for round duct and flue pipe installations in residential and light commercial HVAC systems. It is commonly installed during new construction or retrofit projects where a main duct run must be split into two branch legs of differing diameters. The 7-inch inlet paired with 6-inch and 4-inch outlets accommodates common residential trunk-to-branch transitions. Fabrication meets ACCA and SMACNA standards, making it appropriate for code-compliant ductwork installations across a range of heating and ventilation system configurations.

Key Features

• Hot-dip galvanized steel construction provides corrosion resistance for long-term service in flue and duct environments
• Tee-style wye configuration joins a 7-inch main to 6-inch and 4-inch branches in a single fitting
• Fabricated to ACCA and SMACNA applicable standards for code-compliant installations
• Sheet metal construction allows field trimming or fitting with standard snap-lock or drive-and-s slip connections
• Suitable for both combustion flue exhaust and mechanical ventilation duct applications

Compatibility

Designed as an OEM-style sheet metal wye fitting for 7-inch, 6-inch, and 4-inch round duct or flue pipe systems meeting ACCA and SMACNA fabrication standards.

Installation Notes

Installation should be performed by a licensed HVAC technician or sheet metal mechanic in accordance with SMACNA duct construction standards and applicable local mechanical codes. Shut down the air handling unit or furnace and allow the system to reach ambient temperature before cutting into an existing flue or duct run. Secure all joints with sheet metal screws and approved duct sealant or foil tape rated for the application temperature. For flue and combustion exhaust applications, verify the fitting material and gauge are appropriate for the operating temperature of the connected appliance.
