The genuine Goodman A1781105 vinyl cap is a factory-original sealing plug used on Goodman ACVM960805DXAA gas furnaces and compatible Goodman/Amana models. These small but essential caps seal unused ports, fittings, and access openings to keep combustion air, condensate routing, and pressure-switch tubing free of dust, insects, and moisture intrusion.

Specifications

  • Part Number: A1781105 (OEM Goodman)
  • Type: Vinyl cap / port plug, 1-piece
  • Material: Flexible PVC vinyl
  • Equipment: Gas furnace
  • Fits: Goodman ACVM960805DXAA and related Goodman/Amana furnace platforms

OEM vs. Generic

Generic vinyl caps may be close in size but rarely match Goodman's exact port diameter and durometer, leading to loose fits or seals that crack in high-heat furnace cabinets. This OEM A1781105 is molded to factory tolerances for a secure, lasting seal and preserves your equipment warranty.

Installation Difficulty

Easy (1/5). No tools required — press the cap onto the port by hand. Always shut off power and gas before servicing your furnace.
