This small rubber-and-plastic fitting keeps the observation window secure while maintaining the sealed combustion enclosure the furnace was designed around. A cracked, missing, or hardened bushing lets the sight glass rattle loose and can compromise the combustion-air seal, so replacing it with the correct part restores safe, quiet operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e B1392139\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e View port \/ sight-glass bushing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Furnace fitting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman VMS81005CXAA and compatible 80% furnace platforms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Heat-resistant molded bushing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine Goodman OEM bushing is molded to the exact port diameter and seats flush, holding the sight glass without gaps.
