It is a differential pressure gauge but I am trying to determine what the over pressure limit is? One is 15K the other is 40K. Also any idea is Ruska still even in business??

Ruska was bought by DHI which is now owned by Fluke which is owned by Danaher.
You may want to call Fluke Pressure (the old DHI) and ask.  Jeff Grossman is your area sales rep
