White Rodgers TC18 Thermocouple 18 Inch for Gas Appliances

The White Rodgers TC18 is an 18-inch thermocouple designed for gas pilot light systems in water heaters, furnaces, and other gas appliances. This essential safety component generates a small electrical current when heated by the pilot flame, signaling the gas valve to remain open. If the pilot light goes out, the thermocouple cools and closes the gas valve, preventing dangerous gas leaks.

Key Features:

• 18-inch length provides flexibility for various installation configurations
• Universal design compatible with most residential gas water heaters and furnaces
• Includes adapter nut for secure connection to gas valve
• Comes with metal mounting clip for proper positioning at pilot assembly
• Reliable safety device that automatically shuts off gas flow if pilot flame extinguishes
• Durable construction for long-lasting performance in high-temperature environments

This thermocouple is a direct replacement for worn or faulty thermocouples that cause pilot lights to go out repeatedly. The 18-inch length is one of the most common sizes for residential applications, making it suitable for a wide range of gas heating equipment.
