The Goodman 4053501S Chimney Collar is a factory-original venting component designed for the GMPV125-3 gas furnace. The chimney collar provides the sealed transition between the furnace flue outlet and the vent pipe, ensuring combustion byproducts are directed safely out of the home. A damaged, corroded, or missing collar can lead to flue leaks and improper draft, so a proper OEM-fit replacement is essential for safe furnace operation.
The OEM Goodman 4053501S is dimensionally matched to the GMPV125-3 flue outlet for a precise, leak-free fit and full manufacturer compatibility. A generic equivalent offers comparable fit and durability at a lower cost, making it a smart pick for budget-conscious repairs where an exact factory match is not required.
Easy to Moderate (2 of 3). Installation involves fitting the collar to the flue outlet and securing the vent connection. Ensure the furnace is powered off and cool, and verify a proper vent seal after installation. When in doubt, have the venting inspected by a licensed HVAC professional.
