Tip of the day:
For HVLP guns like mine whose air requirements are toward the low side
this assembly works really good.
Connect air fittings to a tee and install a gage.
Connect the assembly to your gun and regulate the pressure at the
compressor to get what you want at the gun (trigger pulled)
Then you can remove the assembly and have the right pressure
without all the hardware of a regulator, gage, etc.
But, like I said, if you need to really crank up the pressure at the
compressor to get the gun right, this may not work for you.
It works for me with larger fittings and 1/2" hose, and a gun that
only pulls 10 cfm.

That's a cool tip, easy for anyone to do.

Very good tip

For those of you that need higher PSI for workshop tools, have an extra regulator just for your gun hose, and adjust it's pressure as above.

I use one of these with a SATA regulator inside the booth, so I can drop gun pressure to 2 Bar, whilst leaving the workshop tools getting 'full pressure'.
