The Goodman 20201902 is a genuine OEM 23-inch condensate drain hose engineered for the GME950603BXAB high-efficiency gas furnace and compatible Goodman/Amana 96% AFUE models. This flexible tube routes acidic condensate away from the secondary heat exchanger and collector box to the drain trap, keeping your furnace running clean and free of water damage.
The genuine OEM 20201902 hose is cut to the precise length and inner diameter Goodman specifies, so it seats correctly on the collector box barbs without kinking or leaking. Generic aftermarket tubing often has the wrong wall thickness or diameter, leading to slow leaks, water pooling, and premature failure. For condensate handling, OEM fit prevents callbacks.
Easy (1/5). A DIY-friendly swap — power down the furnace, disconnect the old hose from the collector box and trap, slide the new one on, and confirm the drain flows. No special tools required. Always shut off power before servicing.
This is a factory-authorized replacement part backed by Goodman quality. If you are unsure of compatibility, verify your furnace model number before ordering.
