THERMOCOUPLE 750mm M9x1 UNIFIED SLEEVE
750mm long thermocouple, SIT 200 series, with an M9x1mm nut (which suits most SIT control valves including Minisit) and a unified sleeve with slots designed for clamping to pilot brackets, also able to be clamped using a nut also available from our store (BS0.974.036).
Thermocouples are attached to gas control valves as a sensor for the flame/heat, they hold a solenoid open and allow gas to pass when there is a flame present.
they are a safety feature designed to shut off the gas to a burner in the event that the flame goes out (known as “flame failure”).
Particularly suitable for general use (heaters, water heaters, boilers and other gas appliances) which do not require special characteristics.
Normal opening times on ignition and closing times on shutdown.
