• Most that I have seen are 1/8" NPT.

• If you buy an aircraft spruce probe you can get either 1/4npt or 1/8npt, they only cost like 20-25 bucks.

• Go 1/8" NPT as you can always go bigger, but once you see how big 1/8" NPT is you shouldn't want any bigger.

  Yes you will like the Spruce thermocoule.  I think almost everybody gets the 1/8 one and it's faster acting too.  They're fun to watch just by themselve  I would never believed they worked that quick until I put mine in and saw for myself.
