Southwark Metal 78_8X6X6 Sheet Metal Wye Branch 8x6x6

Product Description

The SOUTHWARK METAL 78_8X6X6 is a hot dip galvanized steel sheet metal wye branch fitting used in low-pressure residential and commercial HVAC duct systems. It splits a main duct run into two branch lines, with an 8-inch main inlet and dual 6-inch outlets. Fabricated from hot dip galvanized steel, it resists corrosion in typical forced-air duct environments. This fitting is installed by sheet metal workers and HVAC technicians during new duct construction or retrofit work where a single trunk line must be divided into two supply runs.

This wye branch is suited for rectangular or round duct transition applications in residential and light commercial forced-air heating and cooling systems. The 8 x 6 x 6 inch configuration is a common size for splitting a main supply trunk into two smaller branch runs feeding separate zones or registers. It conforms to ACCA and SMACNA standards, making it appropriate for installations that require compliance with those duct construction guidelines.

Key Features

• Hot dip galvanized steel construction for corrosion resistance in duct environments
• 8-inch main inlet with dual 6-inch branch outlets for trunk-to-branch splitting
• Meets ACCA and SMACNA applicable standards for duct fabrication
• Wye geometry reduces turbulence compared to sharp tee branch fittings
• Sheet metal construction compatible with standard duct connection methods including slip, drive, and screw fastening

Compatibility

Designed as an OEM-style replacement or new-installation fitting for residential and light commercial forced-air duct systems requiring an 8-inch main by 6-inch dual-branch wye configuration meeting ACCA and SMACNA construction standards.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal workers. Shut down the air handling unit and verify zero airflow before cutting into an existing duct system. Seal all joints with listed duct sealant or UL 181-rated tape per local mechanical code requirements. Follow SMACNA duct construction standards for support spacing and fastener type when securing this fitting in the duct run.
