Genuine Goodman A1781105 1-Piece Vinyl Caps

The Goodman A1781105 1-piece vinyl cap is an OEM protective closure for the Amana AMES960805CUAB gas furnace and related Goodman/Amana equipment. These flexible vinyl caps seal unused tubing stubs, drain ports, sensor fittings, and test taps, keeping dust, debris, moisture, and insects out during storage, shipping, or normal operation. The soft, stretch-fit vinyl grips tapered and straight fittings alike for a snug, reusable seal that won't crack like brittle plastic plugs.

Specifications

OEM Part Number: A1781105
Part Type: 1-piece push-on vinyl cap
Brand: Goodman / Amana
Equipment: Gas furnace
Primary Fit: AMES960805CUAB
Material: Flexible molded vinyl
Installation: Tool-free push-on

OEM vs. Generic

The A1781105 is sized to the exact port diameters used on Goodman/Amana furnaces, so it seats flush and stays put. Off-brand caps are often the wrong bore — too loose and they slip off under vibration, too tight and they tear on installation. The OEM part gives a clean, dependable seal every time and keeps your service kit consistent.

Installation Difficulty

Rating: Very Easy (1/5). No tools needed — simply push the cap over the fitting or port until fully seated. Installation takes seconds and the cap can be removed and reused during service. As always, shut off power at the disconnect before opening any furnace panel.
