Bissell Internal Air Duct Koblentz or laminateThis genuine OEM internal air duct fits the Bissell 1383 and related deep cleaners, routing airflow through the machine. It maintains the internal path that carries air where the design intends. A cracked or broken duct leaks air and disrupts the intended flow, which can undercut cleaning performance and stress nearby components. A precise replacement restores the sealed internal path and proper function. Fits: Bissell 1383, 66Q4, 66Q42, 73A5, 8920,
