Honeywell 48 Inch Replacement Thermocouple for Gas Furnaces, Boilers, and Water Heaters, CQ100A1047/U

The Honeywell CQ100A1047/U 48-Inch Replacement Thermocouple is a vital safety component designed for gas furnaces, boilers, and water heaters. It is engineered for compatibility with systems operating on a 30-millivolt power supply. As a safety measure, the thermocouple detects the presence of a pilot flame and ensures the gas valve remains open only when a flame is present, preventing hazardous gas leaks.

Constructed with a heavy-duty, long-lasting element, this model is designed for maximum durability and an extended service life in high-heat environments. Its 48-inch length makes it suitable for larger appliances or configurations that require extra reach. The product includes a universal adapter for easy installation on most pilot burners, including push-in, clamp-in, and screw-in designs. With positive positioning for a secure fit, it allows for a quick and straightforward replacement process to keep heating systems operating safely.
