OEM vs. Generic

Genuine Goodman OEM bushings are molded to exact factory tolerances and rated for the temperatures found at the burner box. Generic bushings may not seat flush, can allow air infiltration that disrupts combustion, and often degrade under repeated heat cycling. For a component that guards the flame-inspection port, the OEM part is the safe choice.

Installation Difficulty

Easy (1/5). Snaps into the existing port opening in minutes with no tools. Always shut off power and gas before servicing. If you are unsure, consult a licensed HVAC technician.

Backed by fast shipping and a 30-day return policy. Order your genuine Goodman B1392139 today to keep your furnace's inspection port sealed and serviceable.
