where can I purchase an oil pressure gauge for excavator?

[RCP57]

I got an oil filled one from a local hydraulic supply shop. I also bought some cheap air pressure gauges from Princess auto that work fine. The trouble for me is that the cheapies only go up to around 15bar. I would imagine that any of the German model manufacturers would sell them too.

MCMaster Carr has them. 5 different ranges in 1 inch dia.
