The genuine Goodman A1781105 1-Piece Vinyl Cap is a factory-original protective and sealing cap for the Amana/Goodman AMVM970803BNAA furnace. Vinyl caps are used to seal unused ports, protect fittings and terminals from moisture and debris, or cover a manifold/tubing connection during shipping and service. Replacing a lost or brittle cap keeps the intended seal intact and prevents contamination of the covered component.

  • Part Number: A1781105
  • Type: 1-piece molded vinyl cap
  • Function: Port/fitting seal and protection
  • Equipment: Goodman/Amana AMVM970803BNAA and compatible models
  • Material: Flexible vinyl
  • Brand: Genuine OEM Goodman/Amana

OEM vs. Generic: The OEM cap is molded to the precise diameter of the port or fitting it protects, giving a snug, retained fit. Generic caps in the wrong size can slip off or fail to seal. For a small part that ensures a proper seal, OEM is the safe pick.

Install Difficulty: Very Easy (⭐☆☆☆☆). Push-on installation by hand — no tools required. A low-cost item worth keeping on hand for routine service and reassembly.
