MPXM2102D pneumatic connection

I have some trouble with the pneumatic connection to the sensor MPXM2102D.

The idea was to use an O-ring seal between pressure sensor and pneumatic block. During test I see that I have too much leakage. A closer look shows that the metal plate is slightly movable (red arrows in pic) Air can escape between metal plate and plastic housing. For test purpose I seal to the plastic housing. Then no air was escaping. The datasheet and the application note "Mounting Techniques, Lead Forming, and Testing of the MPX Series Pressure Sensors" says nothing about mounting.


I have the following questions:

Which sealing is recommended?

Which force to sealing is allowed?


Thanks for helping
