I built a heatstick yesterday, but noticed that there's an thick exposed piece of rubber at the connection end. Does that need to be sealed with JB Weld, or will that be OK in the boil?

It's the black part right under the thread on the heating element

You can see some black stuff exposed, and that's the rubber.

If that's the seal that came with the element, you should ok to run it. If your concerned, submerge it in water to see if it leaks.(unplugged of course)
There is a silicone that is foodgrade if you want to make sure....

I am not worried about the leaks, but about something leeching into my beer.
I looked through a bunch of pictures of heat sticks, and I can't tell what others have done with the rubber seal.

Get yourself a different "nut" one that goes to 1 1/4" not 1 1/2". That will cover the rubber seal and make for a much nicer heatstick. You can pick one up at Lowe's, I haven't seen them anywhere else. In addition I smeared mine with food-grade aquarium silicone before screwing everything together to ensure it all was watertight.

Crap, mine is already sealed with JB Weld. I doubt I can salvage anything from it.

Give it a shot and see how it works, stick it in your pot and boil some water for an hour. Let it cool first, then taste it. If it tastes nasty then start over, if it trips the GFCI then start over. If everything works out well, then you're golden.

Is that sufficient? Just tasting the water? Can something undetectable leech into it?
