The genuine OEM B1392139 is molded from the correct heat-rated compound and sized to the exact port diameter. Generic O-rings or universal grommets may not seal properly or may degrade quickly under combustion heat, leading to air leaks and nuisance flame-sensing issues.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eVery Easy (1\/5).\u003c\/strong\u003e Under 5 minutes—simply pop the old bushing out of the burner-box port and press the new one into place.
