This small bushing seats into the burner compartment cover to form the observation (sight-glass) port, letting a technician safely watch flame ignition and burner operation without opening the sealed combustion area. Though inexpensive, a cracked, missing, or brittle view port bushing can allow air leaks that disturb the combustion-air balance and affect flame quality.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e View port bushing \/ sight-glass grommet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Sealed burner-flame observation port\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e High-temperature molded bushing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e AMS81155CNAA and compatible Goodman \u0026amp; Amana furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e B1392139\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause this bushing must handle sustained heat and seal precisely into the factory opening, the \u003cstrong\u003egenuine Goodman OEM part\u003c\/strong\u003e is the only reliable fit.
