This bushing (sight-glass grommet) seals the burner-compartment inspection port, letting a technician safely observe flame color and ignition while keeping the sealed combustion chamber airtight. A missing, brittle, or melted bushing can allow air leaks that affect flame sensing, combustion pressure, and the furnace's pressure-switch logic. A fresh OEM bushing restores a clean, gas-tight viewing port.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1392139\u003c\/li\u003e\n\u003cli\u003eComponent Type: View port bushing \/ sight-glass grommet\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace burner compartment\u003c\/li\u003e\n\u003cli\u003eFits Model: AMVC81005CNBA\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana\u003c\/li\u003e\n\u003cli\u003eMaterial: High-temperature molded grommet\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM\u003c\/strong\u003e bushing matches the exact port diameter and temperature rating for a leak-free seal. \u003cstrong\u003eGeneric\u003c\/strong\u003e grommets exist but rarely match the precise burner-box opening, risking air leaks in a sealed-combustion furnace.
