[PSUBS-MAILIST] Pressure Test Chamber

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
