The 600mm Universal Gas Thermocouple is designed for homeowners and DIY enthusiasts looking to maintain or repair gas appliance safety systems. Its primary benefit is providing a reliable flame failure mechanism that automatically shuts off gas flow if the pilot light is extinguished, ensuring peace of mind. A key caveat to keep in mind is that while the unit features a universal design, users should verify their specific appliance mounting requirements and fitting sizes before beginning installation to ensure a secure connection.

It is designed as a universal fit for many standard gas valves, but you should verify your appliance's specific thread size and mounting style.
No, you should never cut or modify the length of the thermocouple as it contains a delicate internal conductor that will be permanently damaged.
Generally, a small adjustable wrench is sufficient to tighten the nut at the gas valve and the pilot assembly.
If your pilot flame lights but goes out as soon as you release the control knob, the thermocouple is likely failing to generate enough voltage to hold the valve open.
No, thermocouple threads are typically compression fittings and do not require thread seal tape.
Ensure the thermocouple tip is fully immersed in the pilot flame and that the connection to the gas valve is tight.
Check the copper line for any sharp kinks or structural damage that may have occurred during installation.
Before installation, ensure the appliance gas supply is completely shut off and the unit is cool to the touch. Remove the existing thermocouple, paying close attention to how it is threaded into the pilot assembly and the gas valve. When installing the 600mm unit, ensure the sensor tip is positioned directly in the flame path of the pilot light, but avoid bending the copper tubing into sharp, tight corners which can cause internal damage or signal degradation. Periodically check the sensor tip for carbon buildup and clean it gently with a soft cloth to ensure accurate temperature readings.
