I posted about this trick a few times but finally got around to taking some pics:
Get some silicone tubing from the pet shop, fill the end with some keg lube and push the probe through. Don't even try without the lube. Then get two #70 O-rings, Lowes sells a pack of 10 for $1.50 or something. I put one on the outside of the tubing as a clamp and worked the other one underneath the tubing as a seal. The last one I did only used the O-ring underneath and it didn't leak either.
Now you don't have to worry about tossing the probe in your kettle, MLT or fermentor and having it start reading way off after getting the wire wet.
Note: if you use the aquarium tubing, it's almost certainly NOT 100% silicone. In other words, it doesn't have the 400F+ rating. If you use this stuff in wort/mash you'll be fine if you keep it away from open flame. Don't use it in your oven!!! If you want the real silicone to be able to use it to monitor meats in the oven, go to Mcmaster, USplastics or a hobby shop (they sell silicone tubing for R/C fuel lines).
