These genuine OEM Goodman A1781105 1-piece vinyl caps are direct-fit fittings for the ACES960603BNAA furnace and many other Goodman/Amana units. Vinyl caps seal unused drain ports, manifold openings, and tubing stubs to keep the furnace airtight and protect threaded or barbed fittings from dust, corrosion, and accidental connection. Though inexpensive, a missing cap can cause pressure-switch faults or condensate weeping.

OEM vs. Generic

OEM A1781105 caps are molded to the precise port diameter used on Goodman furnaces, giving a snug, leak-free seal. Generic hardware-store caps often fit loosely and pop off under inducer pressure. At this price, OEM is the clear pick.
