Southwark Metal 52_6X4X3 Sheet Metal Flue Wye 6x4x3

Product Description

The SOUTHWARK METAL 52_6X4X3 is a hot-dip galvanized sheet metal flue wye designed for branching ductwork and venting runs in residential and light commercial HVAC and exhaust systems. This wye fitting connects a 6-inch main line to a 4-inch and a 3-inch branch, allowing the installer to split airflow or exhaust flow at a single junction point. Fabricated from hot-dip galvanized steel, the fitting resists corrosion in the moist, thermally cycled environments common to flue and duct systems. Licensed sheet metal mechanics and HVAC technicians install this type of fitting as part of trunk-and-branch or wye-take-off duct configurations.

This flue wye is suited for round sheet metal duct systems carrying conditioned air or low-temperature exhaust in residential and light commercial buildings. It is appropriate for applications where a 6-inch main duct must transition into separate 4-inch and 3-inch branch runs. The galvanized steel construction makes it a practical choice for both supply and exhaust configurations where moisture exposure is a factor. It meets applicable ACCA and SMACNA standards, making it suitable for installations governed by those industry specifications.

Key Features

• Hot-dip galvanized steel construction provides corrosion resistance in humid and thermally cycled duct environments
• 6-inch x 4-inch x 3-inch sizing allows a single main run to branch into two smaller diameter lines
• Fabricated to ACCA and SMACNA applicable standards for use in code-compliant duct installations
• Sheet metal construction compatible with standard snap-lock and drive-slip duct assembly methods
• Wye geometry reduces turbulence compared to tee-style branch fittings in airflow applications

Compatibility

Designed as an OEM-style sheet metal wye fitting for round galvanized duct systems with a 6-inch main connection and 4-inch and 3-inch branch outlets, conforming to ACCA and SMACNA standards for residential and light commercial HVAC and venting applications.

Installation Notes

Installation should be performed by a licensed sheet metal mechanic or HVAC technician in accordance with SMACNA duct construction standards and local mechanical codes. Shut down the air handling system and verify the system is de-energized before cutting into existing ductwork or securing the fitting. Secure connections with sheet metal screws and seal all joints with UL 181-listed duct tape or mastic sealant as required by local code. Do not use this fitting in high-temperature flue applications beyond the rated capacity of standard galvanized sheet metal.
