Alan,
Never pressurise oil with air to those pressures. An explosion waiting to happen. Oxygen partial pressures!!
If you want to do it use nitrogen.

Alan,
Pressure testing that high needs to be done with liquid not gas. High pressure air is VERY dangerous. A pressure washer pump using water would be a safer choice.

I am making a plastic container to fill with water & stand inside my
pressure chamber. There is a gap between the wall of the container
& the chamber which I intend to fill with oil. There will be about an
inch of air at the top of the chamber & I'm using a scuba tank to
pressurise the unit up to 3000psi.
Will car engine oil do to fill the gap between my plastic container &
the chamber wall, or do I need to go with a hydraulic fluid.
Am using the plastic container to keep water from rusting my test
chamber. (Aussie Steve's idea)
Cheers Alan
