The Goodman B1392139 View Port Bushing is a genuine OEM fitting for the AMH80803BXBD gas furnace and compatible Goodman/Amana models.

OEM vs. Generic

As a precise molded fitting, this genuine OEM bushing seats correctly in the furnace vestibule panel. No reliable generic equivalent exists for this proprietary part, so OEM ensures correct fit and sealing.
