The Goodman 20201802 Condensate Drain Hose Tube is a genuine OEM replacement hose for the Amana/Goodman AMVC950453BXBA high-efficiency gas furnace. It routes condensate between the secondary heat exchanger, drain trap, and inducer housing, keeping the furnace's drainage system sealed and flowing so the pressure switch proves reliably.
Over time factory hoses can crack, harden, or slip off their barbs, leading to slow leaks and intermittent lockouts. Installing the exact OEM tube restores a clean, factory-correct routing without trimming or adapters.
The OEM 20201802 arrives pre-cut to the correct length with the proper inside diameter for a secure, leak-free barb fit. Generic bulk tubing can be sized wrong and may not resist the acidic condensate. For a reliable seal we recommend genuine OEM; a lower-cost generic length is offered where an exact fit is confirmed.
Very Easy (1/5). Under 10 minutes. Power down, slide the old hose off its barbs, press the new tube fully onto each fitting, and check for free drainage. No tools required.
