Campbell Hausfeld H7273 Standard Pressure Regulator

I purchased one of these regulators when I installed a new compressor. It lasted about 9 months and then the inadequate plastic design simply failed. If you use one of these regulators, you can't leave any pressure on the plastic housing inards (when not in use) because it will fatigue and then shatter apart. I found pieces spread all over my garage where the compressor is installed. And when it breaks, the spring, etc from inside the knob go flying all over the place. There are many other reviews else-where that describe the same situation. This regulator should not be sold until the design is corrected.

If you look at the plastic threaded ring, as you can see in the picture, it does nothing. I am not sure but maybe its suppose to have a lip that helps to hold the knob base to the metal housing, but the design doesn't permit that. The result is the internal spring constantly puts pressure on a plastic part that can not bear the stress over any length of time, then it breaks.

Regulator arrived as advertised. It came with ample instructions and once installed it was very responsive and worked as designed. Seems to be a quality product and is currently installed on a craftsman 30 gallon air compressor. Most satisfied with purchase.

Failed after just 1 month. Pressure doesn't stay constant. Starts at 110 psi and drops down to 80 or less during any use and goes back up to 110 when not in use.

This unit worked pretty well and was about what you'd expect from a pressure regulator... for a little less than a year.

I have left this set @ 90PSI pretty much since the day I installed it. I have adjusted it maybe 5 times. About a week ago the pressure started creeping up on it's own and the over pressure release would continually hiss. I have verified that the gauge itself is fine. The regulator is what has failed after less than a year of just sitting there doing nothing.

Additionally, this is one of those units that you have to overadjust if you set the pressure too high. What I mean by that is that if you happen to pass the mark for the pressure you want, you can to turn it counterclockwise a good 5-10 turns before the pressure actually starts to drop, then turn it back up again to get the pressure you were after. That's a pretty minor thing though... just something to be aware of.
