The Goodman B1392139 is a genuine OEM view port bushing for the AMEC960803BNAD gas furnace. This grommet-style fitting frames the sight-glass/observation port that lets technicians view the burner flame and ignition. It provides a clean, sealed opening in the cabinet while protecting the port edge.
The OEM B1392139 is sized to the furnace's factory port opening for a flush, sealed fit rated for the cabinet's operating temperatures. Generic grommets may not tolerate the heat or may leave gaps that allow air infiltration. OEM ensures a proper, lasting seal.
Easy (1/5). Press-fit into the port opening by hand — no tools required.
