The service kits for the MSB9000 are shockingly expensive, however:
No Problem 3000psi service pressure spheres. But from a previous post since removed it looks like I'm not allowed to show you the compressor that fills them LOLInconel spheres? Never heard about that. Do you have pictures Very interesting.

That is really good to hear, @nickbutcher. Makes me feel better about my decisionThe service kits for the MSB9000 are shockingly expensive, however:
I bought my Mini Haskel in 2011 and it was already about 4 years old then. In the 14 years I've been using it, I've pulled the spool out 4 or 5 times and cleaned it up. I pulled the HP end cap off once and it was spotless inside with no visible wear. That's the only 'servicing' it's ever received.
It continues to boost to 250 bar whenever I need to go that high.
I have always driven it with clean banked diving air pumped with my own Bauer PE100 so I've never used drive gas from a cheap shop compressor. And, it's only been used for myself and a few mates but this thing isn't designed for commercial use.
If I ever need to do a full service on it, I'm sure it will be cheaper to try and find another used one. However, that day isn't likely to arrive before I'm too old and decrepit to be diving any longer.
And of the some 3500 different types and grades of steel and not forgetting Aluminium available to the OP it would be helpful if Kim could narrow it down a tadFrom Kim, who quotes the spec from Gordon Smith, the late great designer and manufacturer of the Jetsam Baby Booster:
HP piston (long part): polished steel
LP piston (flat part): Aluminum
