Genuine Goodman B1392139 View Port Bushing

The Goodman B1392139 is the OEM view-port bushing (sight-glass grommet) for AMS80704BXAA gas furnaces and compatible Amana 80% models. 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.

Specifications

Type: View-port / sight-glass bushing
Material: High-temperature molded grommet
Function: Seals flame-inspection port
Mount: Snap/press-fit into port opening
Fits: AMS80704BXAA and Goodman/Amana 80% furnaces

OEM vs. Generic

This genuine OEM Goodman bushing is molded to the exact port diameter and made from a heat-rated compound suited to burner-compartment temperatures. Generic grommets are often the wrong bore size or a lower-temperature material that hardens and cracks prematurely. At this price point, OEM is the obvious choice for a guaranteed snap-in fit.

Installation Difficulty

Very Easy (1/5). A two-minute job with no tools: power down the furnace, pop out the old bushing, and press the new one into the port until it seats. No wiring, gas, or calibration involved. Ideal to add to any furnace tune-up or when replacing nearby burner-compartment components.

An inexpensive genuine part that keeps your inspection port sealed. Questions? Contact info@nationalhvacparts.com.
