This small but essential component seals the burner-compartment inspection window, letting a technician safely observe the flame while keeping the combustion area properly enclosed. A cracked, brittle, or missing bushing can allow air leakage around the port and compromise a clean visual flame check.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e View-port \/ sight-glass bushing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e High-temperature molded grommet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Seals flame-inspection port\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount:\u003c\/strong\u003e Snap\/press-fit into port opening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e AMS80704BXAA and Goodman\/Amana 80% furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003egenuine OEM Goodman\u003c\/strong\u003e bushing is molded to the exact port diameter and made from a heat-rated compound suited to burner-compartment temperatures.
