These genuine Goodman A1781105 1-Piece Vinyl Caps are factory OEM accessories for the Amana/Goodman AMVM970803BNBA modulating gas furnace and related AMVM97-series units. Vinyl caps seal off unused drain ports, pressure taps, or fittings and protect openings from dust, debris, and moisture intrusion. Though small, the correct cap keeps the furnace's condensate and venting configuration sealed exactly as the manufacturer intended.

  • OEM Part Number: A1781105
  • Type: 1-piece vinyl cap / port plug
  • Function: Seals unused ports and protects fittings
  • Compatible Model: AMVM970803BNBA and AMVM97-series
  • Material: Flexible vinyl

OEM vs. Generic: Furnace port caps must fit snugly to maintain the proper pressure and drainage configuration. The OEM A1781105 is molded to the exact port diameter used on AMVM97 cabinets, so it seats securely and stays put. Loose generic caps can pop off, allowing air leaks that affect pressure-switch operation or let condensate weep. For a low-cost part that supports proper sealing, the genuine OEM cap is the easy choice.

Installation Difficulty: Very Easy (DIY-friendly). Simply press the cap firmly onto the correct port or fitting until fully seated. No tools required; takes under a minute. Confirm you are capping the port specified for your furnace's venting/drain orientation.
