A pressure sealed sealing of threads (R-threads acc. DIN 2999 and DIN 3858 and for NPT-threads acc. ANSI/ASME B 1.20.1 – 1983) can be effected with sealants attched on the outside thread.

We recommend the use of 7 to 8 turns of a suitable Teflon-sealant very tautly fixed around the outside thread beginning with the first thread-turn towards the lead of the thread (so the Teflonband connot be loosend when screwing in the threads).

In no case the thread may be turned back when bolting. Otherwise the teflon band would have again to be applied.
