Pressure regulator

I agree with above post but you may want to check for the max pressure rating to avoid possible damage from over pressuring it . ,
It says Max inlet pressure 300 PSI.

The maximum inlet pressure is 300 psi so the regulator is not meant for a cylinder. It is meant for a second stage on a gas distribution system. It should say what gas it is used for.
The 10 - 125 psi range is the design operating range. It can most likely be set (a bit) above 125 psi and it can certainly be set below 10 psi, but it is not designed to work at those pressures - the actual pressure may be neither accurate nor stable.

That seems like a lot of pressure for a second stage gas regulator.
I assumed it was for water?

"The first stage is non-adjustable and reduces the inlet pressure to an intermediate setting (typically 250-350 psig). The second stage is adjustable and reduces the intermediate pressure to the final delivery pressure. "
That's from one of Matheson's catalogues.
I don't know what fluid the regulator was designed for, or it's intended application - so I am just guessing.

Nothing to say it can't be used for air (compressor assumed) but what was it designed for?
Jack
How did you identify this was a matheson?

It was Matheson's catalogue. I used it to get a typical intermediate pressure.
I have no idea what the OP's regulator is.

Are you talking about an air compressor regulator, or for a compressed gas cylinder?
Once you mentioned Matheson (an air gas supplier) this conversation got complicated.
Every regulator for a "bottle" that I've ever seen has the appropriate female fitting attached for a gas bottle.
Air compressor regulators usually have a 1/2" female threaded in and out ports.
A better picture of your reg will be helpful.
@wantacoe is the OP and didn't mention matheson as far as I can tell
@Jack Ryan brought that complication to the table, based on some catalog he was looking at. I'm still not clear how it ties to this thread

You questioned 300psi as an intermediate pressure for dual stage.
I used that catalogue to inform you that that was a typical intermediate pressure.
You then misunderstood the mention of the catalogue.
I clarified in the following post.
You still missed it.

Appears to be an air regulator, possibly a Wilkerson that is sold under a couple names.
Air Regulator, 3/4 In NPT, 470 cfm, 300 psi https://a.co/d/4wmOE2k
@Jack Ryan you can apologize anytime

That was a wild ride.., info correct about a different situations. We had welders giving welding gas info, plumbers giving water pressure regulator info.. : ) I figured compressed air.. but I had my new “compressed air” regulator in my hand last night! (Anchor Bias)
