I don't know if someone else has posted this yet but...

While researching silicone for an aquarium, I discovered RTV615. It is a two part potting silicone (meaning no air contact is needed) that is FDA approved. It is optically clear so you can see if the contacts have become compromised. I think it would make a good contact sealer for those of you whom desire to seal the contacts in PVC couplings.

NOTE!

The product has gone up in price since GE sold off the silicone division. Might be prohibitive...
