This small but important fitting maintains a proper seal around the view port so the combustion chamber stays sealed while still allowing you to observe flame quality during service. A cracked, brittle, or missing bushing can allow air infiltration that disrupts the flame-sensing and pressure balance of the burner assembly.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType: View port \/ sight-glass sealing bushing\u003c\/li\u003e\n\u003cli\u003eMaterial: Heat-resistant molded grommet\u003c\/li\u003e\n\u003cli\u003eFunction: Seals the burner inspection window\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana AMH80904BXAA and related 80% furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1392139\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause this bushing must fit a precise cutout and withstand sustained heat near the burner box, an exact-fit OEM part is the right call.
