You can't submerge the sparkgap in transformer coil --- the firing sparkgap
will tend to breakdown the oil, ie, carburizing it, and soon the oil will
become an erratic insulator.
Gases will work good, especially nitrogen which is cheap. That's how a
quench gap works -- the O2 is quickly burned away leaving N2 (80% of
atmosphere) between the copper electrode faces.
This is also why a quench gap needs to be clamped and the G-10 insulating
material properly machined --- you need a near air-tight chamber between the
copper electrodes. We made a few using 3/16 inch thick copper with circular
machined surfaces raised 1/8th inch on each surface --- then clamped them
very tight with G-10 3/8th inch rod. Performance was very good in the range
2-6 kVA. Nice for a potential xmfr powered system or multiple NST powered
You can't cut them accurate enough with a bandsaw --- they need to be
machined for best performance. If the chambers aren't sealed they become a
standard atmospheric gap --- not a true quench gap similar to the old spark
