It seals the burner inspection port so the flame can be observed safely while keeping the combustion chamber pressure-tight. A cracked, brittle, or missing bushing is a common cause of a loose or rattling view port cover and minor combustion-air leaks.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: View port \/ sight-glass bushing (grommet)\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1392139\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana AMVC80805CXBB furnace\u003c\/li\u003e\n\u003cli\u003eMaterial: Heat-resistant molded elastomer\u003c\/li\u003e\n\u003cli\u003eApplication: Burner compartment inspection port\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM B1392139 is molded to the exact port diameter and temperature rating specified by Goodman, so it seats flush and holds its seal through repeated heat cycles. Generic universal bushings are cheaper but often run oversized or use a lower-temp compound that hardens and drops out. For a small, safety-adjacent combustion part, the OEM piece is the reliable choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Easy\u003c\/h3\u003e\u003cp\u003eRated \u003cstrong\u003eEasy (1\/5)\u003c\/strong\u003e. Power down the furnace at the switch\/breaker, pop the old bushing out of the port, press the new one into place, and reseat the cover. No tools or gas-line work required.
