5.1.1 Sealing the process connection
▶
When screwing the threads of the CPG1500 to an adapter or a pressure connection,
it is necessary to use an additional sealant between the threads, e.g. PTFE tape.
▶
With an NPT connection, the sealing must be made directly on the thread with PTFE
tape and not via the threaded fitting at the CPG1500.
For sealing the process connections with
parallel threads, flat gaskets, lens-type
sealing rings or WIKA profile sealings must
be used at the sealing face
1
.
For sealing process connections with tapered
threads, the sealing is made in the threads
using additional sealing material, e.g. PTFE
tape (EN 837-2).
