The Honeywell Q340A1090 Thermocouple is designed to provide reliable pilot flame sensing for compatible gas-fired appliances. Measuring 36 inches in length, this thermocouple helps ensure safe operation by generating a small electrical current when heated by the pilot flame.

If the pilot flame goes out, the thermocouple signal stops, allowing the gas valve to shut off the gas supply. This safety function helps prevent unburned gas from flowing into the appliance. The thermocouple is commonly used in gas water heaters, furnaces, boilers and other pilot-operated gas appliances.
