The Goodman 4053501S is a genuine OEM chimney collar (flue vent adapter) for the GMNT120-5 gas furnace. This collar forms the sealed connection between the furnace's flue outlet and the vent pipe or chimney, ensuring combustion byproducts are safely carried away. A corroded, warped, or ill-fitting collar can allow flue-gas leakage and poor draft — this factory part restores a tight, code-compliant venting connection.

Type: Flue chimney collar / vent adapter
Function: Furnace flue-to-vent transition
Material: Corrosion-resistant coated steel
Fits: Goodman GMNT120-5 and compatible GMNT series
Category: Flue & venting

OEM vs. Generic: Venting components must match the furnace's flue diameter and mounting pattern exactly to maintain proper draft and a gas-tight seal. This genuine Goodman collar drops in without modification, while generic adapters often require rework and can compromise the vent seal.

Install difficulty: Easy (2 of 5). The collar is fastened to the flue outlet with sheet-metal screws and sealed as required by code. Shut off power and gas, allow the furnace to cool, and inspect the connected vent pipe for corrosion while access is open. Verify draft after reassembly.
