Pressure water-tight connection of cable conduits:



Dear Sir or Madam,


The laying of cables and other media lines in cable conduits is indispensable. In addition to the mechanical protection of the cables, this installation method allows additional cables to be placed after the pipeline route has been backfilled.
With our MASTERTEC Connector family, we offer a professional solution for the connection of the common cable conduit dimensions to core drill holes and lining pipes.


The MASTERTEC Connector has been designed for corrugated cable conduits with outer diameters of
75, 90 and 110 mm.
Based on an application test, the transition has been certified a pressure watertightness of up to
1 bar (10 m water column) by MFPA Leipzig.
