The Goodman A1781105 1-Piece Vinyl Cap is a genuine OEM fitting used to seal or cap unused ports, tubing stubs, or fittings on the ACES960804CNAA gas furnace. Though small, the correct cap prevents air leaks, debris intrusion, and pressure-circuit faults that can affect furnace performance.

Specifications

  • Type: 1-piece molded vinyl cap / plug
  • Function: Seals unused port, tube, or fitting
  • Material: Flexible, weather-resistant vinyl
  • Fitment: OEM diameter for snug, leak-tight seal
  • Compatibility: Goodman ACES960804CNAA and related furnaces

OEM vs. Generic

The OEM A1781105 is sized to the exact port diameter on your Goodman furnace, delivering an airtight, vibration-proof seal. Generic caps that are loose or oversized can pop off or leak, introducing pressure-switch errors or moisture intrusion. For a few cents more, the factory cap removes any guesswork.

Install Difficulty

Very Easy (1/5). Under 5 minutes — simply remove the old or damaged cap and press the new vinyl cap firmly over the port until fully seated. No tools required. As always, ensure the furnace is powered off before servicing internal components.
