This small but essential fitting seals the inspection port on the burner compartment, letting technicians safely view flame ignition and rollout while keeping the combustion cabinet properly closed.

Generic aftermarket bushings often use lower-grade rubber that hardens and shrinks near the burner box, leading to premature failure. For a furnace fitting exposed to heat cycling, we recommend the OEM part.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1\/5).\u003c\/strong\u003e Power down the furnace, pop out the old bushing, and press the new one into the port opening.
