The Goodman 20201901 is a genuine OEM condensate drain hose built for the GMV90905CXBA two-stage, variable-speed 92% AFUE condensing gas furnace. This molded high-temperature tube carries corrosive condensate between the secondary heat exchanger's collector box and the drain trap system. Because condensate is mildly acidic, only high-grade tubing survives long-term; a degraded or split hose leads to cabinet leaks, water damage, and induced-draft pressure faults. The OEM 20201901 restores a properly sealed, correctly routed drain path.
The OEM 20201901 is shaped to the furnace's exact drainage geometry and connector sizes, seating on the barbed ports without adapters. Generic tubing may be the wrong diameter or bend radius, risking leaks and kinks. For a reliable factory seal, use the OEM hose.
Easy (1/5) — About 10–15 minutes. Shut off power, detach the old hose from both fittings, press the replacement fully onto each barb, and verify a secure, kink-free connection. No special tools needed.
