The Goodman 20214203 Condensate Drain Angle is a genuine OEM elbow fitting used to route the condensate line on the GKS90905DXAE gas furnace and compatible Goodman/Amana 90%+ AFUE models. This molded angle connects the collector box or drain trap to the drain hose at the correct pitch, keeping condensate flowing and preventing pooling that can back up into the furnace. A cracked or misaligned drain angle is a frequent source of slow water leaks around the furnace base.
OEM (Goodman 20214203): Exact angle and barb dimensions matched to the GKS90905DXAE drain assembly for a leak-free, correctly pitched connection. Generic: A universal barbed elbow of similar size — lower cost and widely available, but verify the angle and hose diameter match your setup before installing.
Easy (1/5). Cut power, pull the old angle from the drain line, press in the replacement, and confirm a tight, downward-pitched connection. A 10-minute task with no special tools. Check that the trap and downstream hose are clear while you're in there.
