Request Information
Straight-Shank, Threaded Thermowells are available in a variety of materials, process connection sizes, lengths, and optional lagging extensions. Thermowell specifications should be determined based on process conditions which include strength, temperature, pressure and corrosion-resistance requirements. They are designed with a standard 0.260" or 0.385" bore diameter to accommodate sensing elements with either a 0.252" or 0.377" maximum diameter, respectively. These wells are available as separate components or as part of complete sensor assemblies.

N/A Wells are made from round bar with milled wrench hex. 1-1/4 in. National Pipe Thread (NPT) and 1-1/2 in. National Pipe Thread (NPT) wells are supplied as round bar with milled wrench flats.

("U" length for non-lagging wells) = "S" - 1-1/2 in. ("U" length for lagging wells) = "S" -1-1/2 in. -"T" (To solve for "T"), "T" = "S" -"U" -1 1/2 in. (When "U" and "S" are specified)
