Quick Release Couplings - a Tip

Fair enough Dave, I tend to adjust the MAC valve based on how the brush is spraying and how it sounds, rather than turns of the knob. :smiling3:

Same here

That's how I work too. The actual pressure is not important. I adjust the MAC until the airbrush sprays as I want it to.

On the pressure front I do a bit of both. when I started out with an AB last year I started using the pressure gauge but was well aware that the reading on my Chinese compressor gauge might be inaccurate, so then tweaked the pressure until I was happy, and then made a note of what the gauge said it was. So far, touch wood, it's panned out ok.......
