This molded bushing seats into the burner-compartment access panel and secures the sight glass, giving technicians a clear, sealed window to inspect burner flame quality during operation and service. Over time the original bushing can crack, harden, or fall out from repeated heating and cooling cycles — replacing it restores a proper seal and keeps the flame-inspection port safe and functional.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1392139\u003c\/li\u003e\n\u003cli\u003ePart Type: View port \/ sight glass bushing\u003c\/li\u003e\n\u003cli\u003eMaterial: High-temperature molded polymer\u003c\/li\u003e\n\u003cli\u003eMounting: Snap-fit into burner access panel\u003c\/li\u003e\n\u003cli\u003eCompatibility: Goodman \/ Amana AMS80905CNA and related 80% furnaces\u003c\/li\u003e\n\u003cli\u003eColor: Black\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a factory-original Goodman part, guaranteeing exact fit, correct high-temperature rating, and a proper seal at the inspection port.
