Application

  • The spigot-end can be screwed shear-protected to another screw socket.

  • The threaded socket is suitable for the following types of pipes:

  • Cast iron pipes
    - With standard threaded ring fitting: threaded ring, conical ring, sealing ring; external anti-thrust device (No. 5800).
  • Ecopur cast iron pipes
    - Supplied with a standard screw ring assembly. To preserve the external coating, a conical ring (No. 8777) is used in place of the contact ring; external thrust restraint (No. 5800).
  • PE pipes
    - with PE welded end (No. 4524).
  • The use with natural gas must be specified in order for the required testing according to DIN 3230-5 (PG1 for underground valves and PG3 for valves in installations) to be performed, along with the corresponding certificate of acceptance 3.1 according to DIN EN 10204.
