With parallel male threads (e.g. G ½ B) WIKA sealings must be used
„
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.
