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.
