In accordance with the general technical regulations for pressure
gauges (e.g. EN 837-2 "Selection and installation recommendations for
pressure gauges").
When screwing gauges in, the force required for this must not be
applied through the case, but rather through the spanner flats (using a
suitable tool) provided for this purpose on the square shaft of standard
connections.
Installation with
open-ended spanner
For parallel threads, use flat gaskets, lens-type sealing rings or WIKA
profile sealings at the sealing face . With tapered threads (e.g. NPT
threads), sealing is made in the threads  using additional sealing
materials, e.g. PTFE tape (EN 837-2).
The torque depends on the seal used. Connecting the gauge using
a clamp socket or a union nut is recommended, so that it is easier to
orientate the gauge correctly.
