Operational application limits
Pressure (MPa): max. 20
the max. permissible operating pressure depends on the gap dimensions.
Temperature (°C): -30 to + 100
The operational application limits use are dictated by the O-ring selected. It is only the resistance of the sealing system to pressure which can be increased by the STU back-up ring.
