Southwark Metal 52_5X5X4 Duct Wye Tee 5x5x4 in Galvanized

Product Description

The Southwark Metal 52_5X5X4 is a round sheet metal duct wye tee fitting used to split or combine airflow in residential and light commercial HVAC duct systems. Fabricated from hot-dipped galvanized steel, this wye tee measures 5 inches by 5 inches by 4 inches and is designed to handle the branch transitions common in supply and return trunk configurations. Its round profile mates with standard round spiral or snap-lock ductwork and provides a smooth interior transition that limits turbulence at branch points. HVAC sheet metal installers and duct fabricators are the primary trades who work with this fitting.

This fitting suits residential forced-air systems and light commercial applications where a round duct wye branch is required to divert a portion of the main airflow into a smaller run. Typical installations include supply trunk branches in attic, basement, and crawlspace duct systems. The 5-inch main and run with a 4-inch branch outlet makes it a common choice for zoning off a bedroom or secondary space from a larger trunk line. Fabricated to ACCA and SMACNA standards, it fits into systems designed and installed per those guidelines.

Installation Notes

Sheet metal duct fittings of this type are installed by licensed HVAC technicians or journeyman sheet metal workers. Secure all joints with sheet metal screws and seal with UL 181-rated mastic or foil tape per SMACNA and local mechanical code requirements. De-energize the air handling system before making any duct modifications. Do not use this fitting in high-pressure commercial systems or flue gas exhaust applications outside its rated use.
