Sanpress Rotguss V-contour which press jaw

Hello everyone

Can someone help me out

I am currently installing a used grey water system for the toilets. For the pressurized water pipes in the basement for supply, I have chosen stainless steel pipes with Viega Sanpress red brass V-profile.
I ordered a pressing tool with the V-profile but somehow even before pressing the alignment/fit is already missing.
In the unpressed state, the pressing jaw is already touching the bead for the sealing ring. According to Viega, “The sealing element is not deformed during pressing.”

Are there special pressing jaws for the Sanpress V-profile or are they all the same and can be used both for fittings for copper or stainless steel?

You can use the press cheek with V—contour. Only in front of + behind the sealing ring is deformed.

The press jaws are already fully in contact with the O-ring groove.

The groove is also not deformed, as this would also push the O-ring out of the groove and it can no longer seal. The deformation only serves to prevent the connection from being pulled apart.
