The Goodman 20214203 drain angle is a genuine OEM elbow fitting used to route condensate within the ACV90905DXBA condensing gas furnace. This angled connector directs acidic condensate from the collector box and inducer assembly into the drain hose at the correct geometry, preventing pooling and back-pressure that can trip the pressure switch. A cracked or misaligned drain angle is a frequent source of slow leaks and intermittent furnace shutdowns.
The genuine OEM Goodman drain angle matches the exact angle, diameter, and barb profile of the factory drainage system, sealing tightly without adapters. Generic elbows often have mismatched fitting sizes or angles, forcing the drain hose into stressed bends that leak or kink over time. For a watertight, drop-in fit, choose the OEM part.
Easy (1/5) — Power down the furnace, remove the clamps or push-fit connections on either side of the old angle, install the replacement in the same orientation, and reconnect. Takes about 10 minutes with basic hand tools.
