Goodman A1781105 Vinyl Cap Kit

The Goodman A1781105 is a genuine OEM 1-piece vinyl cap designed for the AMEC960303ANAB gas furnace. These caps seal unused ports, ductwork knockouts, and wiring pass-throughs to keep conditioned air, insulation, and debris where they belong. Because Goodman and Amana share the same parts platform, this cap is a factory-correct fit for the AMEC-series cabinet.

Specifications

OEM Part Number: A1781105
Type: 1-piece vinyl cap / plug fitting
Material: Molded vinyl, temperature-rated for furnace cabinet use
Fits Model: AMEC960303ANAB (Goodman / Amana 96% AFUE gas furnace)

OEM vs. Generic

This is the authentic Goodman-specified part, molded to the exact diameter and flange of the original so it seats flush with no air leaks. Generic universal caps are often oversized or under-sized and can pop loose or whistle under blower pressure. When you want a leak-tight seal that matches the factory build, choose the OEM A1781105.

Installation Difficulty

Easy — DIY friendly (1/5). No tools required in most cases; simply press the cap into the matching opening until fully seated. Always shut off power and gas to the furnace before servicing. If you are unsure of the correct opening, consult your furnace wiring/parts diagram or a licensed HVAC technician.
