The Goodman 20214203 Drain Angle is a genuine OEM condensate fitting for the GCH91155DXAE high-efficiency gas furnace and compatible Goodman/Amana models. This molded angled (elbow) fitting connects the furnace's drain hoses to the condensate trap and drain assembly, redirecting acidic condensate around tight cabinet clearances without kinking the tubing.
OEM vs. Generic: The genuine 20214203 fitting is molded to the exact angle and barb diameter this cabinet requires, ensuring a leak-free press-fit connection. Generic elbows may not match the hose ID, leading to slow leaks, condensate pooling, and potential water damage or nuisance lockouts. OEM guarantees a sealed, correctly routed drain path.
Install difficulty: Easy (1/5). Replacement takes about 5–10 minutes: power off the furnace, remove any clamps, pull the drain hoses off the old fitting, and press them firmly onto the new angle. Confirm a continuous downhill flow and inspect all joints for leaks after the furnace restarts.
