Mechanical connection
In accordance with the general technical regulations for pressure measuring
instruments (e.g. EN 837-2 "Selection and installation recommendations for
pressure gauges").
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.
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 a suitable sealing material (EN 837-2).
