With tapered female threads (e.g. 9/16-18 UNF) the process connec-
tion seals metallically without additional sealing.
When screwing the instruments in, the force required for sealing must
not be applied through the case, but only through the spanner flats
provided for this purpose, and using a suitable tool.
The tightening torque is dependent on the selected process
connection.
