Genuine Goodman A1781105 1-Piece Vinyl Cap

Part number A1781105 is an OEM single-piece vinyl cap used on the Goodman/Amana AMVC960803BNBA 96% AFUE modulating gas furnace. These caps plug unused ports, seal off capped drain or pressure-tap openings, and protect fittings from debris and moisture intrusion. Though small, a correctly seated cap is important for maintaining proper pressure-switch operation and preventing air leaks that can trip nuisance lockouts on a sealed-combustion furnace.

Component Type: 1-piece vinyl protective cap / plug
Compatible Equipment: AMVC960803BNBA and related Goodman/Amana furnaces
Application: Port sealing and fitting protection
Material: Flexible vinyl, weather- and heat-resistant

OEM vs. Generic

This genuine Goodman cap is molded to the precise diameter of your furnace's ports for a snug, airtight fit. Generic vinyl caps often run loose or too tight, which can allow air infiltration or fall off over time. The OEM part guarantees the correct seal and keeps your unit within factory specification.

Installation Difficulty: Very Easy

A no-tool, push-on replacement suitable for any homeowner. Simply remove the old or missing cap and press this one firmly onto the port until seated. No adhesive or fasteners required.
