The Goodman 20201802 Condensate Drain Hose Tube is a genuine OEM replacement component engineered for the Goodman GMH950453BXAA high-efficiency gas furnace and other compatible 90%+ AFUE models. As a condensing furnace, the GMH95 series produces acidic condensate that must be routed safely to the drain system — this hose tube carries that condensate from the collector box or drain pan to the trap without leaks or restrictions.
Generic drain tubing is often sold by the foot and cut to approximate length, which can lead to poor sealing at the barbed fittings and eventual condensate leaks that damage the heat exchanger and control board. The OEM 20201802 is molded to the exact length, bend, and diameter Goodman specifies, ensuring a factory-tight connection and protecting your warranty coverage.
Easy (1/5). Replacement typically takes under 15 minutes: power down the furnace, disconnect the old tube from the barbed fittings, seat the new tube, and confirm the drain trap is primed. No special tools required. Always verify condensate flow after reassembly to prevent nuisance lockouts from the pressure switch or float safety.
Keep your Goodman furnace running efficiently with genuine OEM parts. Order the 20201802 drain hose tube today for fast, reliable shipping.
