Genuine Goodman 20513001 Evaporator Drain Fitting

The Goodman 20513001 is an OEM condensate drain fitting engineered for the Goodman GMP125-5 gas furnace and compatible Goodman/Amana equipment. It connects the evaporator or heat-exchanger drain pan to the condensate line, routing moisture safely away from the cabinet. Using the factory part guarantees a leak-free, code-compliant fit that generic push-in fittings can't reliably match.

Specifications

OEM Part Number: 20513001
Type: Evaporator / condensate drain fitting
Compatible Model: Goodman GMP125-5 (and select Goodman/Amana furnaces)
Material: Molded polymer, corrosion-resistant
Application: Gas furnace condensate drainage

OEM vs. Generic

Genuine OEM fittings are molded to exact Goodman drain-port dimensions, ensuring a watertight seal and preventing pan overflow or water damage. Universal fittings often require adapters, shims, or sealant and are a common source of nuisance leaks and float-switch trips. For a maintenance-free repair, OEM is the safer choice.

Install Difficulty

Easy (1/5) — Hand-installable in minutes with no special tools. Disconnect the drain line, remove the old fitting, seat the new one, and reconnect. Confirm proper drainage after startup.

Always disconnect power and gas before servicing your furnace, and consult a licensed HVAC technician if you are unsure.
