The Goodman 20214203 Drain Angle is a genuine OEM condensate elbow fitting designed for the GCV90905DXBA high-efficiency gas furnace and related Goodman models. This angled fitting directs condensate from the collector box or inducer drain into the trap and drain line at the correct pitch, ensuring gravity flow and preventing standing water that leads to pressure-switch faults, freeze-ups, and heat-exchanger corrosion.
OEM vs. Generic: The factory 20214203 is molded to the exact angle and barb dimensions of the Goodman drain assembly. Generic elbows often use the wrong bend radius or barb size, causing loose connections and slow leaks. Choosing the OEM fitting guarantees a sealed, correctly-pitched drain path and protects your warranty.
Install Difficulty: Easy (1/5). Turn off furnace power, remove the old fitting and hoses, press the new angle into place, and re-secure the clamps. No special tools required; typical replacement takes 5–10 minutes.
