This bushing seals the observation port on the burner or blower compartment, allowing the flame or interior to be inspected while maintaining the correct compartment seal for proper combustion-air pressure and safe operation. Cracked, brittle, or missing bushings can leak air, distort flame sensing, and let dust into the cabinet.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1392139\u003c\/li\u003e\n\u003cli\u003eFunction: View\/sight port seal and bushing\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace burner compartment (AMVC800804CXAB and compatible)\u003c\/li\u003e\n\u003cli\u003eMaterial: High-temperature molded grommet\u003c\/li\u003e\n\u003cli\u003eFit Type: Direct OEM replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause this bushing seals a pressure-sensitive compartment, the exact outer diameter and flange thickness matter.
