Seal
Correct sealing of the process connections with parallel threads at
the sealing face
must be made using suitable at gaskets, sealing
rings or WIKA prole 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 sealings see WIKA data sheet
AC 09.08 or under www.wika.com.
