Straight Van Stone Thermowell

Brand: Pyromation

Straight Van Stone Thermowells are available in a variety of materials, flange sizes, and pressure ratings. They are also available in various lengths and with optional lagging extensions.

Thermowell specifications should be determined based on process conditions which include strength, temperature, pressure and corrosion-resistance requirements.

Straight Van Stone thermowells are supplied with a 0.260" or 0.385" bore diameter to accommodate sensing elements with a 0.252" or 0.377" maximum diameter, respectively.

Van Stone thermowells are connected using a separate and reusable lapped backing flange, eliminating the need for expensive flange materials.

These wells are available as separate components or as part of complete sensor assemblies.
