Van Stone Thermowells

Van Stone Thermowells

The Ashcroft® Van Stone thermowell is used when pressure, high velocity and corrosive process media exist. Designed to mate between two existing flanges.
The Ashcroft® Van Stone thermowell isolates and protects a temperature instrument’s sensing element from pressurized, high velocity and corrosive media. They ensure longer life and accurate measurement while allowing the sensing instrument to be removed without shutting down the process. A wide selection of materials, sizes and dimensions are available.
