The Goodman 20214203 is a genuine OEM condensate drain angle fitting designed for the WGFM295070V4CAB high-efficiency gas furnace. This molded elbow redirects condensate flow at the correct angle between the collector box and the drain trap assembly, maintaining proper slope for gravity drainage and preventing standing water inside the cabinet.
The OEM 20214203 is molded to the precise angle and barb dimensions the WGFM cabinet requires, so it seats securely and holds a leak-free seal. Universal aftermarket elbows frequently sit at the wrong pitch, which can trap condensate, trip the pressure switch on flooded traps, and cause nuisance lockouts. The factory fitting eliminates guesswork.
Easy (DIY-friendly). Push-fit onto the existing drain hoses and secure with clamps; verify slope toward the trap. Roughly 10 minutes with no special tools. Cut power and gas before working on the furnace.
