These molded vinyl caps seal unused knockouts, drain ports, and tubing stubs on the furnace cabinet and inducer assembly, keeping the pressure and condensate circuits sealed and preventing air leaks or debris intrusion. Though small, a missing or degraded cap can create a pressure-switch fault or allow conditioned air and combustion by-products to escape.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e A1781105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e 1-piece vinyl cap \/ plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e AMSS960402BNAA and matching Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Flexible molded vinyl\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquipment:\u003c\/strong\u003e Gas furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e This factory cap is molded to the exact port diameter and depth used on Goodman furnaces, giving a snug interference fit that stays put through thermal cycling and vibration.
