This small but important component seals the inspection port on the burner\/heat-exchanger compartment, letting a technician safely observe the flame while keeping the combustion area sealed and rated. A cracked, brittle, or missing bushing can allow air leakage that affects flame stability and safe combustion.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFunction: view-port \/ sight-glass sealing bushing\u003c\/li\u003e\n\u003cli\u003eOEM part number: B1392139\u003c\/li\u003e\n\u003cli\u003ePrimary fit: Goodman WFD18090S4BXCC furnace\u003c\/li\u003e\n\u003cli\u003eEquipment type: gas furnace combustion \/ inspection port\u003c\/li\u003e\n\u003cli\u003eMaterial: heat-resistant molded grommet\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause it sits at the combustion inspection port, this bushing must hold its shape and seal under sustained heat.
