The Goodman 20201901 is a genuine OEM condensate drain hose tube engineered for the Amana/Goodman AMVC950453BXAB modulating high-efficiency gas furnace. On 90%+ AFUE condensing furnaces, secondary heat exchanger condensate must be routed cleanly to the drain trap — this factory-spec tube ensures a leak-free, correctly angled path that protects the burner box and control board from moisture damage.
Generic drain tubing is sold by the foot and rarely matches the molded bends and inside diameter this furnace requires, which can cause kinks, pooling, and nuisance pressure-switch lockouts. This OEM Goodman 20201901 is cut and formed to factory dimensions for a drop-in fit with no trimming or guesswork, preserving the manufacturer's designed drainage slope.
Easy (1/5) — Slip-fit connection, typically no tools required beyond a hose clamp. Most homeowners and technicians complete the swap in under 10 minutes. Always shut off power and gas before servicing.
