The Goodman A1781105 1-Piece Vinyl Caps are a genuine OEM fitting component engineered for the ACVC961005CNAA furnace and compatible Goodman/Amana high-efficiency models. These caps seal and protect port openings and unused fittings on the furnace cabinet, preventing air leakage, debris intrusion, and moisture entry during operation and storage.

  • OEM Part Number: A1781105
  • Type: 1-piece vinyl cap fitting
  • Material: Durable molded vinyl
  • Equipment: Furnace (gas)
  • Compatibility: Goodman ACVC961005CNAA and related ACVC9 series

OEM vs. Generic: This genuine Goodman cap matches the factory dimensions and durometer exactly, ensuring a leak-free press fit. Generic alternatives often run loose or brittle, leading to vibration rattles or premature cracking. For a sealed, factory-correct result, OEM is the safe choice on a high-efficiency furnace.

Install Difficulty: Easy (1/5) — push-in replacement, no tools required. Always disconnect power before servicing your furnace.

What symptoms mean I need a new fitting?

Is this fitting compatible with Bryant or Payne too?

To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Goodman fitting?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
