The Goodman A1781105 1-Piece Vinyl Cap is a genuine OEM accessory used on the ACEC960803BNAB and a wide range of Goodman/Amana HVAC equipment. These flexible vinyl caps seal unused ports, protect tubing ends, cover pressure taps, and keep dust, moisture, and debris out of fittings during shipping, storage, and service.

Though small, a missing or torn cap can allow air leaks at pressure ports or contamination of open lines — leading to inaccurate pressure readings and avoidable service calls. Keeping correct OEM caps on hand makes routine maintenance cleaner and faster.

  • Part Number: A1781105
  • Type: 1-piece flexible vinyl protective cap
  • Function: Seals and protects ports, tubing ends, and fittings
  • Fits: Goodman ACEC960803BNAB and many other models
  • Brand: Goodman OEM

OEM vs. Generic: The OEM A1781105 is sized to grip the exact port and tube diameters used on your equipment for a snug, secure seal. Generic caps often fit loosely and can pop off under vibration or pressure. OEM provides a dependable, factory-correct fit.

Install Difficulty: Very Easy (1/5). Push-on installation in seconds — no tools required.
