This small but essential grommet seats the burner-compartment sight glass (view port), allowing safe visual inspection of the flame while sealing the inspection opening against air leaks and combustion byproducts. A cracked, missing, or hardened bushing can cause a poor seal, nuisance pressure-switch faults, and unsafe viewing conditions — this direct-fit replacement restores factory tolerances.\u003c\/p\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 (fitting)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman\/Amana AMH81005CNBD and compatible 80% furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Heat-resistant molded grommet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Seals and retains the burner viewing window\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine OEM B1392139 is molded to the exact diameter and durometer specified by Goodman, ensuring a leak-tight snap fit.
