A Trane GKT04089 Gasket seals economizer flange connections to curb air leakage and preserve consistent airflow within the assembly.
The gasket creates a tight seal at the economizer flange so the HVAC system can maintain proper airflow and reduce leakage at the connection point. Its .031-inch thickness, 11.850-inch outside diameter, 16 bolt holes and silicon bead design matter because they support even compression, proper alignment and reliable sealing performance in heating and cooling equipment.
The gasket may need to be replaced if the heating and cooling unit shows airflow loss, reduced economizer performance or leakage around the flange connection. Physical signs can include cracking, flattening or tearing and you might notice moisture, dirt buildup or air escaping near the sealed area.
