This small but essential component seats the sight-glass viewing port on the burner compartment, letting technicians safely observe the flame during startup and diagnostics. A cracked, brittle, or missing bushing can allow air leakage around the inspection port and compromise a clean seal, so replacing it with the correct OEM part restores proper fit and function.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: B1392139\u003c\/li\u003e\n\u003cli\u003eType: View Port \/ Sight Glass Bushing\u003c\/li\u003e\n\u003cli\u003eCategory: Furnace Fitting\u003c\/li\u003e\n\u003cli\u003eCompatible Model: AMV80905CXA (Goodman\/Amana 80% gas furnace)\u003c\/li\u003e\n\u003cli\u003eMaterial: High-temperature molded polymer\u003c\/li\u003e\n\u003cli\u003eFit: Direct OEM replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a factory-original Goodman component, machined to exact port dimensions for a leak-free, drop-in seal.
