The Goodman 20513001 Condensate Drain Fitting is a genuine OEM replacement component engineered for the GMPE100-4A gas furnace and other compatible Goodman/Amana models. This fitting routes condensate away from the heat exchanger and collector box, preventing water pooling, corrosion, and nuisance safety-switch lockouts caused by blocked or leaking drain connections.

Specifications

Part Number: 20513001
Type: Condensate / evaporator drain fitting
Equipment: Goodman gas furnace (GMPE100-4A)
Material: Molded polymer, corrosion-resistant
Fit: Direct OEM replacement — no modification required

OEM vs. Generic

Choosing the genuine OEM Goodman 20513001 guarantees an exact dimensional match to the collector box and drain port, ensuring a watertight seal the first time. Generic or universal fittings often require adapters, silicone sealant, or trimming, and a poor seal can flood the burner compartment or trip the pressure switch. For a reliable, long-term repair, OEM is the safe choice.

Installation Difficulty

Easy (DIY-friendly). Replacement typically takes 10–15 minutes with basic hand tools. Power down the furnace at the disconnect, drain any standing condensate, remove the old fitting, seat the new one, and verify a leak-free connection before restoring power. If you're unsure about the condensate path, consult a licensed HVAC technician.
