Leaking Condor reg. valve

[skorec]

My Condor regulated valve leak via very little hole near the black bottle - see the  little blowholes  inside soap water bubble  on the hole.  These hole probably  vents the spring disc space between  two O-rings - see the another picture.
I have cleaned it and also I have changed all O-rings but very slow leaking continues.

Is it because :
1.   I have set higher output pressure than is recommended ( R:80-140 bar I have set 160-190 bar )
2.   Wrong design ?
3.   Wrong spring discs set ?
4.   Another issue ?

No any opinion for leaking ?
No any experiences with MYOT Condor valve ?

Looking at the drawing,i don't see differences between this design and a common paintball regulator,except for the adjustement.
If the regulator leaks from the ventil hole,the leak comes from the piston seals or the tube seals.
If you replaced the o rings and the slow leak is still here,i would take a look at the surfaces where the o rings seats on.
Even a tiny scratch or debrises can cause a slow leak.
All this assuming the o ring grooves are properly dimensioned.
