Is there any reason that you wouldn't want to use silicone caulk to seal off the dangerous end of a RIMS tube?

are you talking about using it to cover the electrical connections to the heater element?

yeah... I decided it would be better to use that than the normal JB weld type potting... Will it work or do I need to rip it apart and clean all that crap off of it?

Somebody posted recently that the silicone they used specifically warned against its use on certain metals, corrosive as I recall. Sorry I can't remember the post. Check the manufacturers info on the brand that you used.

I didn't see anything about it being corrosive... I also didn't see anything about its dielectric capabilities either...

I tried sealing up a small housing around my kettle's element with silicone caulk, and the stuff just didn't stick to the metal very well.

It seems to be sticking just fine. I'm really just worried about the insulating properties of it.

I used liquid electrical tape. It takes several coats, but works well!

Well, if the housing around the connections is reliable, then it's probably fine. Good idea by the way; I dread the day my element kicks. I'm not even going to eff with chipping away epoxy! I'm cutting the cord and starting from scratch.

If you make sure you get it all the way in and around the connections and let it cure, it should be fine....at least enough to ward off condensation and the odd droplet.

"Since the acetic acid is released during curing, it can attack the
underlying substrate material. This can cause corrosion of certain
metals and prevent the proper adhesion of the silicone. However, on
other materials, the acid can etch the surface slightly and increase the
adhesion. Aluminum is one such material. Copper and zinc, however, are
corroded by the acid.
Thus brass and galvanized steel should not be used
with silicones which release acid. Dissimilar metals can form
electrolytic couples and corrode severely underneath a covering of acetic
acid releasing silicone. Silicones do not adhere well to all other
plastics either.
