Goodman A1781105 1-Piece Vinyl Cap

The A1781105 is a genuine OEM 1-piece vinyl cap for the Goodman/Amana AMVC960804CNBA 96% AFUE gas furnace. These caps seal unused tubing ports, cover pressure-tap fittings, and protect open connections from dust, insects, and condensate intrusion. Replacing a lost or brittle cap keeps the furnace's pressure-sensing and drainage circuits clean and sealed, preventing nuisance faults.

Specifications

  • OEM Part Number: A1781105
  • Type: 1-piece push-on vinyl cap
  • Function: Seals and protects unused ports and fittings
  • Material: Flexible vinyl
  • Compatibility: AMVC960804CNBA and related Goodman/Amana furnaces
  • Brand: Goodman (Amana-compatible)

OEM vs. Generic

The OEM A1781105 is molded to the precise port diameters on this furnace, so it stays put and seals without falling off. Generic caps are often loose or too tight, and a cap that pops off can open a pressure circuit and cause a lockout. At this price, the exact OEM fit is the smart choice.

Installation Difficulty

Very Easy (1/5). Simply push the cap onto the target port or fitting until seated. No tools required. As always, disconnect power before servicing the furnace.
