Or is it the transmission fluid?
Or the oil?
If you design the pump properly the high pressure circuit is contained within the low pressure circuit. I think a decent seal can contain 30-60 PSI.
Now if you are talking about a beat to snot Bobcat with 7500 hours on it, that is about the same as a 65 Lincoln with 600,000 miles and no maintenance.

Agreed.
As mentioned, keeping a hydraulic system sealed is not a problem.
Manufactures have no problem sealing even high pressure common rail fuel systems in diesels.
In common rail systems, a high pressure pump stores a reservoir of fuel at high pressure — up to and above 2,000 bars (29,000 psi) without leaks.
A Hydraulic Hybrid would use no where near that pressure making it even easier to seal.
