NPT Swivel to Pressure Gage Fitting Question

   / NPT Swivel to Pressure Gage Fitting Question #11  
Permently mounting a $20 bourdon tube style gauge on a piece of mobile machinery is pretty much asking for a major leak sooner or later regardless how the fittings match up.
Iv got one on the 7520 hyd pump output. It is throttled by the thread helix of a setcrew I put into the inlet of the fitting feeding it off the pump outlet. Feed is about 10 drops/second max. Also, it is a liquid damped gauge.

What mechanical gauge would give better durability?
