This premium 26-gauge galvanized steel C-vent tee is a critical component for residential and commercial HVAC venting systems. Designed for durability and efficient airflow, this metal venting fitting allows for the seamless connection of a 4-inch branch line into a 5-inch main exhaust run. Commonly used for venting gas-fired appliances such as water heaters, furnaces, and boilers, its single-wall construction provides a reliable path for combustion gases to exit the structure safely. The heavy-duty 26ga steel ensures structural integrity and resistance to corrosion over time, making it an ideal choice for contractors and DIYers looking for professional-grade exhaust ducting solutions.
Our team is happy to help you verify compatibility before you order. We'll confirm it fits your specific furnace model.
