Well, the IR regulator blew out again yesterday. Took me mere minutes to swap out to the new one I ordered from McMaster Carr. I am so glad I put a shut off valve right on the tank so I don't have to drain it to work on my air lines.
McMaster doesn't like to tell you what brand they are going to send you, but the paper work with the regulator says its a Norgren. I've never even seen Norgren before, but that name sounds familiar. So, will I be replacing it again in less than a year or is it likely to be a better quality regulator. It wasn't much more expensive than the IR regulator. Maybe $10 difference.
