The Goodman A1781105 1-Piece Vinyl Cap is a genuine OEM protective cap used on the AMSS960803BNAA gas furnace to seal unused ports, tube ends, or fitting stubs. These caps keep debris and moisture out of pressure taps and drain ports during shipping and installation, and are used to plug ports that a given venting or drain configuration leaves unused. Replacing a missing or cracked cap prevents air leaks that can affect pressure-switch operation.

Specifications

OEM Part Number: A1781105
Type: 1-piece vinyl protective / sealing cap
Function: Caps unused ports and tube ends; blocks debris and moisture
Fits: AMSS960803BNAA and various Goodman/Amana furnaces

OEM vs. Generic

The OEM vinyl cap is molded to the exact port diameter and depth used on Goodman/Amana furnaces, giving an airtight friction fit. Generic caps often fit loosely and pop off under vibration or slight pressure, defeating the seal. For a part this inexpensive, the correct OEM fit is the obvious choice.

Installation Difficulty

Very Easy (1/5). Push the cap firmly over the port or tube end until seated. No tools required — about 1 minute. Ensure the port is clean and dry for the best seal.

Genuine Goodman part, ideal to keep as a service spare. Ships fast.
