As many have pointed out, the quality of these devices is pretty terrible. There is no static relief, meaning the only thing holding the connector to the cable are 3 very, very thin wires. That being said, the cable itself seems to have some flaws. I have a broken wire somewhere. By moving the cable (while the paddles and connector at the end of the probe are perfectly still), I randomly get high temperature readings or none at all. Finally, the thread is not NPT. They are G1/4 like most imported valves, gauges etc. In general you can seal them with enough tape, especially for gravity applications. If it's a 60psi+ process line, you probably won't get it to unseal. Of course, if you're using this in a thermowell, it doesn't matter.
