OEM vs. Generic

While hardware-store caps exist, the OEM A1781105 is molded to Goodman's exact port diameter for a snug friction fit that won't blow off or leak. Off-brand caps that are slightly oversized can fall off; undersized caps split. The factory cap ensures reliable sealing and correct fitment.

Installation Difficulty

Very Easy (1/5). No tools required. Simply press the cap firmly onto the port or tube end until fully seated. To remove, pull straight off. Always de-energize and shut off gas before working inside the cabinet.

A small but essential OEM component to keep your Goodman furnace clean and properly sealed.
