This high-performance 18-inch thermocouple is a critical safety component for gas-fired heating appliances. Designed to generate a 30 millivolt (30mV) electrical signal when heated by a pilot flame, it serves as the primary sensor for maintaining safe gas valve operation. If the pilot light goes out, the thermocouple cools rapidly, triggering the gas valve to close and preventing fuel leaks. Built for durability and quick response times, this thermocouple is suitable for a wide range of residential and commercial heating systems, including furnaces, boilers, and water heaters. Its standard design allows for easy integration into existing pilot burner assemblies, making it an essential replacement part for restoring the safety and efficiency of your gas appliance.
