Stainless Steel Thermowells

We offer a range of stainless steel thermowells machined from solid bar for use with 6mm diam. temperature sensors.

They are 12.7mm O.D. and are available with a 1/2 inch BSP taper process entry thread and 1/4 inch BSP parallel sensor entry thread. Use a 1/4 in BSP stainless steel fitting to attach the sensor to the thermowell.
