Goodman A1781105 Vinyl Cap — OEM Furnace Fitting

The Goodman A1781105 is a genuine 1-piece vinyl cap used on the AMEC960302BNAB 96% AFUE gas furnace and compatible Goodman/Amana models. These protective caps seal unused ports, terminals, or fastener openings, keeping out dust, moisture, and debris while giving the cabinet a finished OEM appearance. Because it is a factory part, it matches the original diameter and grip tension exactly — no trimming or improvising with generic plugs.

Specifications

Genuine Goodman/Amana OEM part number A1781105
Configuration: 1-piece molded vinyl cap
Category: Furnace fitting / port cover
Fits: AMEC960302BNAB and related 96% AFUE furnace platforms
Material: Flexible vinyl for a snug press fit

OEM vs. Generic

Generic vinyl caps are sold in mixed-size bags and often fit loosely, back out over time, or crack when exposed to furnace-cabinet heat. The OEM A1781105 is molded to the correct bore and durometer for this equipment, so it stays seated through thermal cycling and vibration. For a low-cost part, the OEM piece is the safe choice.

Installation Difficulty

Easy (1/5). Push-fit installation by hand — no tools required. Simply align the cap with the opening and press until fully seated. Suitable for DIY homeowners and technicians alike.
