Though inexpensive, these caps play a real role in furnace performance: an unsealed or missing cap allows air infiltration that can disrupt cabinet pressure, affect condensate routing, and trigger pressure-switch sensitivity. Replacing a lost or brittle cap restores the factory seal.\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 One-piece push-in vinyl cap\/plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman VCES960603BNAA and compatible furnace models\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Seals unused ports and cabinet openings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Flexible 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 The genuine Goodman cap is sized to the exact port diameter for a snug, airtight press fit.
