The Goodman 20201901 Condensate Drain Hose Tube is a genuine OEM part for the AMH950453BXAD 95% AFUE furnace. It channels acidic condensate through the furnace's internal drainage system, linking the collector box, trap, and outlet. Because condensing furnaces run continuous condensate during heating, a degraded or clogged hose is a frequent cause of water on the floor and airflow-proving faults. This heavier-gauge tube handles a primary drainage run in the cabinet.
The OEM hose arrives pre-sized with the correct diameter and bend for this model, so it seats leak-free on factory fittings. Generic alternatives may need trimming and can vary in wall thickness and chemical resistance. For reliable, leak-free drainage we recommend OEM.
Very Easy (1/5). Shut off power, photograph the routing, remove clamps, slide off the old hose, and install the replacement along the same path. Reclamp and check for kinks. About 15–20 minutes.
