Tailwind Thermocouples

Overview

The A.O. SMITH 100108267 is a thermocouple kit designed for use in gas-fired heating appliances. It generates a 30-millivolt (mV) output signal that holds the gas valve open when the pilot flame is proven, providing a critical safety shutoff if the pilot goes out. The kit is identified by model designation TC-K24 and measures up to 24 inches in length, making it suited for installations where a longer lead is required between the pilot burner assembly and the gas valve. Licensed plumbers and HVAC technicians are the typical installers of this component. This thermocouple kit is intended for residential and light-commercial heating applications, including gas water heaters, boilers, and furnaces that use a standing pilot ignition system. The 24-inch length accommodates a range of equipment configurations where the pilot assembly sits at a distance from the main gas valve. Always verify the thread type and tip configuration against the existing equipment before installation. Key Features 30 mV output compatible with standard millivolt gas valve circuits Up to 24 inches in length for flexible routing in tight installations Standing pilot safety shutoff function — gas valve closes automatically on pilot loss TC-K24 kit format includes hardware needed for a complete replacement Compatibility Designed as an OEM-style replacement thermocouple kit for gas-fired heating appliances equipped with standing pilot ignition systems and standard millivolt gas valves.
