I had a free regulator given to me and it has 1/8" NPT inlet and outlet fittings and I think it is severely limiting my impact and other air tools. It may be that it is an old piece of junk, as it doesn't adjust just has a constant 120 psi, and it had a leak that went away. I am not sure about that. But anyways, I need a new regulator. Looking for suggestions on a good regulator at a good price. Not anything crazy, I am just a home garage mechanic. Thanks!
