Goodman A1781105 1-Piece Vinyl Caps

The A1781105 is a genuine OEM one-piece vinyl cap used on the Goodman/Amana AMEC960603BNBA gas furnace to seal unused drain ports, cap tubing stubs, and protect exposed fittings from dust, debris, and moisture intrusion. Though small, these caps play a real role in keeping the furnace's pressure and condensate paths sealed as designed. A missing cap can allow air leaks that affect pressure-switch operation or let debris enter open ports.

Specifications

Part number: A1781105
Type: 1-piece flexible vinyl cap / plug
Fits: Amana/Goodman AMEC960603BNBA and compatible furnaces
Material: Soft vinyl
Application: Port sealing and fitting protection

OEM vs. Generic

The OEM cap is molded to the precise port diameter on this furnace for a snug, air-tight press fit. Generic rubber plugs may be loose or too tight, and often lack the temperature tolerance needed near furnace components. The OEM part ensures a correct seal every time.

Installation Difficulty

Very easy (1/5). Simply press the cap onto the port or tubing stub by hand — no tools required. Under a minute to install.
