This 4-inch galvanized spun plug serves as a durable and reliable solution for sealing off or terminating round ductwork in residential and commercial ventilation systems. Manufactured from high-quality galvanized steel, this vent cap offers excellent resistance to rust and corrosion, making it ideal for high-moisture exhaust applications. It is commonly used to close unused openings in clothes dryer vent lines, kitchen range hood exhausts, bathroom fans, and general HVAC ducting. The spun design provides a precise, snug fit for standard 4-inch round pipes, ensuring a secure seal that prevents air leaks and keeps unwanted debris, pests, or moisture from entering the ventilation network. This metal duct plug is an essential component for maintaining proper airflow and system efficiency when a vent line is no longer in use or requires a clean termination point.
Our team is happy to help you verify compatibility before you order. We'll confirm it fits your specific furnace model.
