The Goodman A1781105 1-Piece Vinyl Caps are genuine OEM protective caps used on the Goodman ACVC961205DNBA modulating gas furnace and compatible ACVC96 / GCVC96 equipment. These vinyl caps seal off unused tubing ports, fittings, or terminals — keeping out dust, debris, and moisture, and preventing air leaks at capped connections during installation and service.

Specifications

OEM Part Number: A1781105
Type: 1-piece vinyl protective cap
Material: Flexible vinyl
Function: Seals unused ports, fittings, and terminals
Fits: Goodman/Amana ACVC96 furnaces incl. ACVC961205DNBA

OEM vs. Generic

This factory-original Goodman cap is molded to the precise diameter of the ports it protects, giving a snug, air-tight fit. Generic caps that are loose or oversized can fall off or fail to seal, allowing air bypass or contamination at sensitive pressure-switch and drain connections. OEM fitment guarantees the correct seal.

Installation Difficulty

Very Easy (1/5). Simply push the cap firmly onto the port or fitting until fully seated. No tools required, and replacement takes under a minute. Confirm a snug fit so the cap stays in place through normal furnace operation and vibration.
