The Davies, Craig 1/8" NPT Thermal Sensor is an alternative size to the 1/4" NPT Thermal Sensor which comes standard in most Davies Craig Fan Switches and EWP Controller Kits.

Sensor: Tapered thread (threads that taper along the thread profile and decrease in diameter as you travel down the part)

*Note: this is only the sensor, if you also need the connector cable, please look at part 0468
