Square D Class 9012 Pressure switch

[R.Little]

HI Looking for some support on the above pressure switches. after calibrating these and fitting to plant we have found the internals full of oil.  these are just new switches but unsure if there is a degradation method that allow this to happen?  Oil Circuit 100-120 Bar
