Southwark Metal 52_6X4X4 Sheet Metal Flue Wye 6x4x4

Product Description

The SOUTHWARK METAL 52_6X4X4 is a hot-dip galvanized sheet metal flue wye fitting used to split or combine airflow in round duct systems. Built to 6 x 4 x 4 inch dimensions, this wye provides a clean branch takeoff in residential and light commercial HVAC ductwork, B-vent flue runs, and exhaust piping. The hot-dip galvanizing process delivers corrosion resistance suited to both conditioned and unconditioned spaces. HVAC technicians and sheet metal installers rely on this type of fitting to maintain proper airflow balance when routing branch ducts from a main trunk. It meets ACCA and SMACNA fabrication and installation standards.

This fitting is appropriate for residential and light commercial forced-air heating and cooling systems, ventilation runs, and flue exhaust applications where a three-way wye connection is required. The 6-inch main with dual 4-inch branches makes it a common choice for trunk-to-branch transitions in supply or return duct systems. It is installed by licensed sheet metal workers or HVAC technicians during new construction or retrofit duct work.

Key Features

• Hot-dip galvanized steel construction for corrosion resistance in duct and flue environments
• 6 x 4 x 4 inch configuration for trunk-to-dual-branch transitions
• Meets ACCA and SMACNA applicable standards
• Sheet metal construction compatible with standard round duct fittings and collars
• Wye geometry promotes smoother airflow compared to sharp tee branches

Compatibility

Designed as an OEM-style replacement and new-installation fitting for round sheet metal duct systems requiring a 6-inch main inlet with two 4-inch branch outlets, per ACCA and SMACNA standards.

Installation Notes

Installation should be performed by a qualified HVAC technician or licensed sheet metal worker in accordance with SMACNA duct construction standards and local mechanical codes. Shut down the air-handling system and confirm the system is de-energized before fitting replacement or duct modification. Secure connections with sheet metal screws and seal joints with UL 181-listed duct tape or mastic sealant to prevent air leakage. Support the fitting per SMACNA hanger and support requirements to avoid stress on branch connections.
