Harbor Freight Pressure Reducing Valve/Air Flow Regulator

I believe that the "145 Max PSI" means that that is the max pressure that it will allow, and not the max psi that can go into it. It has been working fine for me for 3 months now, reducing 175psi down to 120psi

Thank you for posting this.. I've apparently had mine installed backwards for the last year. I never had to really regulate any pressure until today and I couldn't figure out what was wrong! Switched orientation and it works like magic.

You're welcome. Mine is still working perfectly

I set it for 120 psi and just leave it there for all my air tools. It only drops a few lbs even with the blow gun wide open. I have never looked at the gauge while using my impact gun...still working great to this day 11-21-18

That seems like a great deal for 80CFM @ 100PSI. How much of a pressure drop do you see with an impact gun?

This is super cool, Thanks for sharing, I'mTrying to buy a air pressure regulator for the first time do all of them have a pressure relief valve ?
What i want to do is create my own tire filler that I can set to 30 or 35 psi ( ideally to 33 PSI and ) and then have the regulator reach that pressure and then vent out

I don't know if you can find one that can be set that low
