I have a homemade glass soda bottle bong and I need something to seal my metal socket wrench head bowl to a drilled hole in the glass bottle that it fits into. I obviously need the seal to stay strong and airtight at high temperatures. Also, I connect plastic tubing from the metal bowl down into the bong water so I should probably get something that can seal the plastic tubing to the metal bowl as well. Is there something I can buy to do this that can also somehow be purposely removed easily so that I take out the bowl to clean it and replace the plastic tubing occasionally? Heres a diagram of the bong. Orange - Carb Hole Red - Socket Wrench Head Bowl Yellow - Plastic Tubing
