I would get one of these:
McMaster-Carr no. 8457K24
304 SS at .257 ID so the probe will fit inside.
That is my plan....
EDIT: sorry I put in the wrong numbers.... now they are right
EDIT EDIT: My tubing came and this is to small for the probe sold by LOVE...

Get a size bigger.
EDIT EDIT EDIT: Buy your probes from Derrin. They are great and he has excellent service.
