Stucchi Quick Couplings tutorial nr 2: the Brinelling effect

Hydraulic systems undergo severe pressure and impulses and quick couplings too are affected to these, especially if not coherent with the forces involved.
One of the consequences is the Brinelling effect in the crown containing the locking spheres.

Have a look at the animation below to better understand what this is about and discover the Stucchi solutions (Flat Face Screw quick couplings) to solve this problem!
