The Goodman B1392139 View Port Bushing is a genuine OEM fitting for the WFM18070S4BXCB furnace and compatible Goodman and Amana equipment. This small bushing/grommet lines the sight-glass viewing port on the burner or combustion compartment, allowing a technician to safely observe the flame while sealing the panel opening and protecting cabinet sheet metal from wear.

Though inexpensive, a missing or cracked view port bushing can allow air leakage around the port and expose a sharp panel edge. Replacing it with the exact OEM part restores a clean, snug seal at the viewing opening.

Part Type: View port bushing / grommet fitting
OEM Part Number: B1392139
Fits Model: WFM18070S4BXCB (verify against your unit)
Function: Seals and lines the flame sight-glass port opening
Brand Compatibility: Goodman, Amana

OEM vs. Generic

Because this is a small press-fit part sized to a specific panel cutout, the genuine OEM bushing guarantees the correct outer diameter and lip to snap in and hold. Generic grommets rarely match the exact port diameter and tend to fall out. At this price point, OEM is the obvious choice.

Install Difficulty

Easy. Simply press the old bushing out of the port opening and snap the new one into place — no tools required. A quick, few-minute replacement any homeowner or technician can perform with the power off.
