Wyes were created to allow you to vent several areas with one fan. When you need to branch off your duct run to a smaller size a duct wye branch is the perfect fitting to use. They are great fittings for sustaining maximum airflow through your system while branching off to other locations. All wyes are made from high quality galvanized steel.
Installation tips and tricks – To prevent any air leakage it is recommended that you seal the seams with a duct sealant after installation. This will aid in increasing the efficiency of the system and reducing your utility bills.
