What is a Hermetic Seal
A hermetic seal is a seal, which is practically airtight. Such seals are secure against water vapor and other foreign bodies and thus ensures proper working of its contents.
Hermetic seals are vastly found in semiconductor electronics and optical devices.

What is Transformer Oil?
Transformer Oil
Transformer oil, or insulating oil, is usually a highly-refined mineral oil that is stable at high temperatures and has excellent electrical insulating properties. It is used in oil-filled transformers, some types of high voltage capacitors, fluorescent lamp ballasts, and some types of high voltage switches and circuit breakers. Its functions are to insulate, suppress corona and arcing, and to serve as a coolant.
