This bushing lets a technician safely observe the burner flame while maintaining the seal of the combustion chamber. A missing, melted, or brittle bushing allows air infiltration around the port, which can affect combustion draft and pressure-switch behavior — the factory part restores a clean, heat-resistant seal.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e B1392139\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e View Port Bushing \/ Sight-Glass Grommet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Model:\u003c\/strong\u003e VCES960403BNAA (Goodman gas furnace)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Seals and frames the burner flame-viewing port\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e High-temperature grommet material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Direct OEM replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e bushing is sized to the exact bore of the furnace's viewing port and rated for the heat near the combustion area.
