compromised gauges

[cheap]

I have lost the functionality of a couple of gauges due to condensation inside messing up the paper caused by taking the tank in and out of the fridge to carbonate. Are there sealed gauges available? Is there any other way to fix this short of a hole in the side of my fridge?

OK, opened one up and realized that they are aluminum. Why are they fouling? they seemingly slide and pinch the "hand"? I don't think that I am bouncing them much, wtf?
