Application

  • Two-part multi-range coupling straight for repairing fibre cement, cast and plastic pipes.
  • The coupling can also be used for drilling pipes under pressure.

Characteristics

  • The separate sealing packs for the specific pipe make it possible to centre the coupling exactly.
  • The cone-shaped sealing collar on the pipe allows for a pipe tolerance of up to 30 mm.
  • The sealing collar is made from EPDM rubber.
  • The outlets at the top and bottom facilitate an assembly without pressure, as well as additional connection options.
  • Flanschen-Anschlussmasse
    - nach EN 1092-2
  • Betriebstemperatur
