These thermowells are designed for use with Miljoco liquid-in-glass and solar industrial thermometers. They are intended to separate and protect the thermometer from the process or media being measured and allow for the removal of the thermometer without shutting down the process. They are readily available in brass to suit a wide range of applications. The thermowell should be primed before thermometer installation with a heat transfer medium such as oil, graphite or paste to provide optimal accuracy and response time.

Quality machining, exactly as described. I put this on a small infloor radiant heating system. Also bought their stick thermometers. Nice place to purchase this contractor grade material.
