Air pressure gauges - do they just wear out or is there a way to maintain them?

I have some gauges that don’t work very well anymore and
I’m wondering if there’s something I can do to service them
or do I need to replace them to get accurate readings?

May just need calibration… see if there is a way to adjust the readout.
Also… if you are using a compressor, check to make sure you don’t have water in your tank… or if you have a separator that it is working properly…. both of these can cause corrosion and the gauge to go bad internally.

I specified gauges in a past life. I say they do wear out just like your watch wears out. In the price range of most of our gauges just toss it and buy a good replacement. Like most of the things we have, quality is based on cost. If you really want a good gauge, look for a Wika or Marsh. Those are 2 of the better gauges that come to mind. There are others but my mid didn’t bring them to the surface this morning. Yes they wear out.

I may buy a six pack on ebay. I’ve been acquiring more
and more machines that use air to operate and have gauges
vulnerable to damage.

Most gauges you’re likely to use at home aren’t going to be serviceable. Industrial machinery operating within tight pressure tolerances could have calibrated gauges that would have serviceable parts, but in my experience they are very expensive. The bourdon tube inside the gauge tries to extend with pressure inside and relaxes when pressure is relived, this movement over time causes fatigue in the metal and they will loose their precision. Better ones last longer, cheaper ones don’t.

Have your say...
