The Garland 2200706 Gas Range Thermocouple Retaining Nut is designed to maintain a firm connection between the thermocouple and its mounting point in compatible commercial gas ranges. This retaining nut mechanically secures the thermocouple assembly and preserves proper alignment with the pilot flame so the sensing tip can accurately detect heat. A stable connection reduces unwanted movement, supporting dependable thermocouple operation and consistent communication with the gas safety system.
