The Goodman 0154A00000BL drain pan gasket is the genuine OEM seal for the condensate drain pan on ARUF042 series air handlers, including the ARUF042-00A-1B. It creates a watertight seal between the drain pan and the cabinet, preventing condensate from leaking past the pan and causing water damage or rust.
This factory gasket is die-cut to the exact pan profile, so it seats cleanly and compresses evenly for a dependable seal.
Trimmed-to-fit generic gasket material often leaves gaps or compresses unevenly, leading to slow condensate leaks. The OEM 0154A00000BL is pre-cut for a guaranteed factory seal.
Easy. Replace during routine drain pan service — clean the mating surface, set the gasket, and reseat the pan. Most installs take under 20 minutes with the unit powered off.
