The sealing faces at the pressure transmitter and the measuring point always
■
have to be clean.
Only ever screw in, or unscrew, the instrument using the spanner flats. Never
■
use the case or the cooling element as a working surface.
The correct torque depends on the dimensions of the process connection and
■
the gasket used (form/material).
When screwing in, do not cross the threads.

the sealing face
using suitable flat gaskets, sealing
rings or WIKA profile sealings. 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).
For further information on seals see WIKA data sheet AC 09.08 or under www.wika.com.
