Versa Gauge Thermowells
For Bi-Metal Thermometers

Versa Gauge offers various bi-metal thermowells to assure perfect alignment with the thermometer stem and creation of a "sealed system". With this sealed system, the thermometer can be removed from the application without the need for shutting down or draining the system. (See Page 99 for temperature/psi ratings). Versa Gauge offers various Bi-metal Thermowells with a 0.26" (6.604mm bore standard). (Other bore measurements available). Brass thermowells are not recommended for installations involving high pressures and/or temperatures over 400F. Brass or stainless steel cap and chain available to keep bore clean when not in use.
