We have the possibility of having approved materials for the following certifications:
- Open screw test to avoid leakages, especially in the case of double lip gaskets
- Closed screw test for testing the leak-tightness of the plates
- Running torque test to eliminate too hard screws (O-rings assembled with larger dimensions, lack of grease, brass parts outside the tolerance values, etc.) or too soft screws (double-lip gasket and missing O-rings, parts outside the tolerance value, non-suitable pressing of the brass gasket, etc.) from the production lots.
