Tube, Secondary Air (0.16 Hole 86643

This secondary air tube is designed to deliver additional oxygen into the upper area of a wood-burning stove’s firebox, supporting cleaner and more efficient combustion. By helping burn off excess gases and smoke, it improves heat output while reducing emissions. Replacing a damaged or deteriorated air tube restores proper airflow inside the firebox and helps ensure the stove operates efficiently and reliably during normal heating use.
