The Goodman 20214203 is a genuine OEM drain angle fitting for the AMVC950704CXBA variable-capacity gas furnace and compatible Goodman/Amana high-efficiency models. This molded elbow redirects the condensate drain line around cabinet obstructions, connecting the collector box hose to the trap or drain outlet at the correct angle for proper flow.
The OEM 20214203 matches the exact barb diameter and angle Goodman specifies, giving a snug, leak-free press-fit on the drain hoses. Generic elbows may have mismatched barb sizes that leak or pop off under thermal cycling. On a condensing furnace, a secure drain path is essential to avoid corrosion and lockouts.
A simple DIY replacement (about 10 minutes). Power down the furnace, disconnect the drain hoses from the old fitting, press the new angle onto each hose barb, and verify the joint is tight with no drips during a test run. No special tools required.
