Rated 5 out of 5 by 1reviewer.
Rated 5 out of 5 by I had to buy this new Speedaire regulator to replace the one that was working fine until I decided to repair it. I screwed up an "O" ring that turned out to be tougher to replace than I predicted and with no rebuild kits available, I was on the hook for a new one. My old one featured an all steel body and dome. My new one sports an aluminum body and a guard to protect the polycarbonate water separator. Although this unit is slightly smaller than my original, it seems solid enough to last for years as long as I don't perform any non-needed repairs. July 19, 2012
