Frequently Asked Questions

What is the Junkers Thermocouple 300mm W125 WR400 used for?

The Junkers Thermocouple 300mm W125 WR400 is a boiler spare part used to detect pilot flame presence in gas-fired boilers and water heaters. It generates a small voltage to keep the gas valve open when the flame is lit, ensuring safe operation and preventing gas flow when no flame is detected.
