Static seal working pressure

When there is no retaining ring, the maximum pressure can reach 20MPa;

With retaining ring, the maximum pressure can reach 40MPa;

When using special retaining ring, it can reach 200MPa at most.

Dynamic seal working pressure

When there is no retaining ring, the maximum pressure can reach 5MPa;
