If not, what epoxy/silicone is 'food-safe'" for use with a drinking water vessel?

Help me understand what you're trying to do because there might be a better solution than epoxies and sealants. In any case, JBweld is food safe.

I'm trying to patch a hole in a plastic conical fermenter and wondering what material I can trust to use for this that won't be bad for my wort/fermenter. Also I'd like to attach/insert a thermometer into my mash tun (cooler) and would probabaly need something to seal that, that is 'food safe' as well. Any suggestions?

I'll bet JB weld would work just fine. I just read that it's food safe. Some aquarium sealants are as well, but I'd read the MSDS for the product before buying it.

Do you mean like three posts ago ?

I am interested in this also because I have an Igloo cooler (was my MLT will now be my HLT if I can fix the holes) that I popped three holes in on my last batch and I need to fix them somehow.

Reading on JB Weld's website the only product that they specifically state is food grade is WaterWeld. The 2 part epoxy sold as JB Weld is shown as non-toxic.

If fish can live in it, especially salt water fish, it must be safe!

BTW, never use a commercial sponge for cleaning a saltwater tank (RIP)...

JB weld has been used in many applications on theboards, as far as patching cornies etc. You should be good, just check the package of what you're buying (I'm pretty sure its on there).

Yes silicone caulking is safe for drinking water. Make sure you read the labels to verify no goofy stuff was added such as anti-mold chemicals, etc. Also make sure it is given time to cure too.

I was told that anything water grade is considered food grade. I can't see anything in a fish tank not being food grade.

Aquarium silicone is food grade, but many silicone sealants are not. They all run about the same price so if you can find the DAP aquarium sealant, that's what I would use.
