The Goodman A1781105 1-Piece Vinyl Cap is a genuine OEM fitting for the ACVM971005CNAA furnace. These caps seal off unused drain ports, pressure taps, and tubing connections, keeping the condensate and venting system airtight and free of debris. A missing or cracked cap can allow air leaks that disrupt the furnace's pressure-switch readings or let condensate weep.

OEM vs. Generic

The OEM Goodman A1781105 is molded to the exact diameter of the furnace's ports for a snug, airtight push-on fit. Generic caps may be loose or too tight, compromising the seal. For a part this inexpensive, OEM is the obvious choice for guaranteed fit.

Installation Difficulty

Very Easy — under 2 minutes and no tools required. With the furnace off, simply push the vinyl cap firmly onto the port until fully seated. Confirm it is snug and that the surrounding connections remain leak-free.
