The Goodman A1781105 1-Piece Vinyl Cap is a genuine OEM protective fitting used on ACVM970804CNBA furnaces and a wide range of Goodman/Amana equipment. This molded vinyl cap seals unused ports, protects exposed terminals or tubing ends, and keeps debris and moisture out during shipping, storage, and service. Though small, the correct cap preserves the integrity of the connection it covers.

  • Part Number: A1781105
  • Type: 1-piece molded vinyl protective cap
  • Function: Seals and protects ports, terminals, or tube ends
  • Material: Flexible, weather-resistant vinyl
  • Compatibility: Goodman ACVM970804CNBA and related models
  • Quantity: Sold as a single piece

OEM vs. Generic: The OEM A1781105 is sized to the exact port diameter on your equipment for a snug, secure fit. Generic caps are often loose or too tight, allowing moisture intrusion or splitting on install. For a clean factory-correct seal, choose OEM.

Install Difficulty: Very Easy (1/5). Simply press the cap onto the port or terminal by hand — no tools required. Installation takes seconds. Ensure the cap is fully seated for a complete seal.
