Honeywell Q340A1066 18" Thermocouple With Universal Adapters

Thermocouples generate a thermoelectric current that sense a pilot flame on a gas-fired heating systems. The pilot flame heats the tip of the thermocouple producing a temperature differential between it and the base. This temperature difference generates a small amount of DC power, measured in millivolts.

Honeywell Q340A1066 Features:

• Push-in clip, split nut, and adapter assembly for easy pilot burner installation.
• Spade or quick-connect terminals available for millivolt gas control connections.
