Amana-Goodman 4053501S Square to Round Chimney Kit

The Amana-Goodman 4053501S Chimney Collar is an OEM square-to-round chimney service assembly designed to ensure proper venting of combustion gases in compatible Goodman / Amana furnaces. It transitions a square flue opening to a round duct, enabling correct connection between the furnace’s exhaust outlet and the round flue pipe. This component is often used in Goodman’s GDT, PGB, and PGJ series gas furnaces, among others. Manufactured with durable metal construction, the 4053501S is built to withstand heat, vibration, and exposure within the furnace’s venting environment.
