Seal
Correct sealing of the process connections with parallel threads at the sealing
face
must be made 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.
