Pipe threads for pipes and tube connections with sealing tapes (see pages 8 – 10) are sealing inside the threads
Description:
The conical NPT-outside thread shows at the relating level &147;. The adjustment power created by using of a suitable tool increases the thread reach and seals the screw connection supported by a suitable sealant (e.g. hemp or Teflon). Since both inside and outside threads are conical, more thread-turns contribute to better sealing and power admission. The little thread-flattening causes a small leakage space.
