Mechanical connection

 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 ats (using a suitable tool) provided for

this purpose on the square shaft of standard connections.

Correct sealing of pressure gauge connections with parallel threads  must be

made using suitable sealing rings, sealing washers or WIKA prole 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. When a blow-out device is tted to a pressure gauge, it must be

protected against being blocked by debris and dirt.

With safety pressure gauges (see dial symbol

) ensure that the free space

behind the blow-out back is at least 15 mm.
