Auber thermocouple screw

Has anyone used the Auber instruments TC-K3 thermocouple - the one with the 1/4-20 screw ?

How did you make it watertight ? I though the element was watertight, but instead it seems the thermocouple is loose and could (would) leak even if the threads were sealed.



I want to mount this into my cooler.

That's a great question. Does it even fit through the cooler wall?

Machine screws are not sealing. NPT (national pipe thread) is designed to seal as parts are screwed together.

But here's a thought until someone more intelligent contributes: use some silicone air hose from a pet supply store (alla https://www.homebrewtalk.com/f11/remote-probe-thermometer-wort-proofing-26905/) and waterproof the wire/probe interface. Then you should just be able to toss it in the cooler, shut the lid, and not worry about it.
