Manufacturing company I used to work for used tanks of compressed 
nitrogen to pressure test hydraulics before fluid filling.  I think it 
was around 3,000 - 4,000 psi.  Pretty sure they got it from the welding 
supply place, along with the other gas bottles.

Just be damn sure you use appropriate pipe, fittings, etc rated to 
handle it!  Jackass maintenance guy at the place used a plumbing grade 
fitting on one of the test rigs, and it exploded off and nearly killed a 
guy.  Luckily it narrowly missed and embedded itself in the wood roof 25 
feet up.  Honestly, it's pretty dangerous stuff and I wouldn't want it 
in my place.
