Hydac makes their prodrugs up to 600 bar, which is around of 8700 Psi ...
Overpressure saf(e)ty up to twice of the pressure.
That's a hell of a drug.
At the time i still worked for them, we had a "little" accident.
We used Minimess ( the name is misleading) tubes, which can last up to 650 bar,
with a testing lab for 450 Bar with an oil capacity of over 200 liters pressured oil.
One time one got damaged with a pin point hole and the oil shoot out in a fine oil beam.
Which created a wonderful oil mist. lol
Someone lost their finger tip, while trying to get a hold of such a damaged tube.
Cut off by 450 bar oil beam.
We left the room, closed the door, locked it and powered off remotely and let the oil spray around til the pressure lowered to zero. A wonderful oily mess.
If one would've thrown a lightened match into that room as we detected the leakage, after we came back from lunch, booom.
