The Goodman A1781105 1-Piece Vinyl Cap is a genuine OEM fitting used on Amana AMES960803BNAA furnaces and compatible Goodman/Amana equipment. These protective vinyl caps seal off unused tubing ports, protect wire terminals, or cover fittings to keep out dust, moisture, and debris during installation and service.

Though small, the correct cap keeps ports clean and connections protected, preventing corrosion and airflow issues over the life of the furnace. Replacing lost or brittle caps with the OEM part ensures a proper, snug fit.
