Sime Thermocouple T Couple 6180011A

The Sime T Couple (part 6180011A) is a thermocouple supplied as a spare for Sime heating appliances. A thermocouple sits in the pilot flame path and generates a small voltage that holds the gas valve open, so it is central to safe ignition and flame supervision. This unit is listed by the supplier under the Sime thermocouple spare range and carries the alternative number 2043208.
