Goodman A1781105 1-Piece Vinyl Cap

The A1781105 is a genuine OEM 1-piece vinyl protective cap used on the Goodman/Amana AMVS960805CUAA furnace and a wide range of compatible Goodman and Amana equipment. These flexible vinyl caps insulate and seal unused ports, terminal ends, or tubing stubs, keeping dust, moisture, and pests out of connection points and protecting bare terminals during service and shipping. Though inexpensive, a missing cap can allow corrosion or debris intrusion at a sensitive connection.

Specifications

Type: 1-piece flexible vinyl protective cap
Function: Seals and insulates ports, terminals, or tube ends
Fits: AMVS960805CUAA and compatible Goodman / Amana furnaces
OEM Part Number: A1781105

OEM vs. Generic

The OEM A1781105 is sized to the exact port/terminal diameter it caps, so it seats snugly without slipping. Generic hardware-store caps come in mixed sizes and often fit loosely. For a guaranteed snug fit, choose the OEM part.

Installation Difficulty

Very Easy (1/5). No tools required — simply push the cap onto the port or terminal. A less-than-1-minute job. Ideal to keep a few spares on hand during furnace maintenance.
