In accordance with the general technical regulations for pressure gauges
(e.g. EN 837-2 "Selection and installation recommendations for pressure
gauges").
If the pressure gauge is mounted lower than the pressure tapping, the
capillary must be flushed thoroughly before connection in order to clear out
any foreign matter.
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.
Correct sealing of pressure gauge connections with parallel threads
be made using suitable sealing rings, sealing washers or WIKA profile seals.
The sealing of tapered threads (e.g. NPT threads) is made by providing the
thread , with additional sealing material such as, for example, 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.
