This small but critical component seals the flame-observation port on the burner compartment, holding the sight glass securely while maintaining the combustion-chamber seal. A cracked or missing bushing can let combustion gases escape the viewing port, so replacing it with the exact OEM part keeps your furnace running safely and to spec.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1392139\u003c\/li\u003e\n\u003cli\u003eType: View port \/ sight-glass bushing (grommet)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \u0026amp; Amana AMH81205DXBA gas furnaces\u003c\/li\u003e\n\u003cli\u003eMaterial: High-temperature molded polymer\u003c\/li\u003e\n\u003cli\u003eApplication: Burner-compartment flame observation port\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine Goodman B1392139 is molded to the precise diameter and temperature rating required for the burner-box port.
