This small rubber\/grommet fitting seals the sight-glass opening on the burner compartment cover, allowing a technician to visually inspect the burner flame while keeping the combustion area properly closed. Over time these bushings dry out, crack, or fall out — a missing view port bushing can allow air leakage around the burner box and should be replaced to keep the cabinet correctly sealed.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: View port \/ sight-glass bushing\u003c\/li\u003e\n\u003cli\u003eFunction: Seals flame-inspection opening on burner cover\u003c\/li\u003e\n\u003cli\u003eMaterial: Heat-resistant grommet\u003c\/li\u003e\n\u003cli\u003eLocation: Burner compartment access panel\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \u0026amp; Amana AMS80903BNA and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eBrand: Genuine Goodman OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM B1392139\u003c\/strong\u003e is sized to the exact port diameter and rated for the temperatures seen near the burner box.
