The Goodman 22309501 Flue Vent Pipe is a genuine OEM combustion-venting component engineered for GKS90453BXAD gas furnaces. This flue section routes hot combustion byproducts safely from the heat exchanger to the vent system, and its precise dimensions ensure a leak-free seal at the inducer and collector box connections. A damaged, corroded, or improperly sealed flue pipe can cause flue-gas spillage and nuisance pressure-switch trips, so replacing it with the correct factory part is critical for safe, reliable furnace operation.
This is the genuine Goodman OEM part, manufactured to the exact tolerances of your furnace's venting path. Generic or fabricated substitutes may not seal correctly at the inducer housing, risking combustion-gas leaks and failed pressure-switch readings. For a safety-critical venting component, we recommend the OEM part.
Moderate — Requires shutting off gas and power, disconnecting the existing flue section, and confirming a gas-tight seal. Because this part carries combustion gases, we recommend installation by a qualified HVAC technician who can verify draft and check for spillage after service.
Backed by our exact-fit guarantee and fast shipping. Order the Goodman 22309501 today to restore safe venting on your GKS90453BXAD furnace.
