DUROFLEX PLUS IAS 3-layers pliable conduit

  • CLASS:33332

DUROFLEX PLUS new 3-layers conduit drive the revolution in concealed type installations in concrete. The corrugated external wall of the conduit provides the necessary flexibility and the required mechanical strength with the use of less raw materials. The internal smooth wall ensures the smooth insertion of the cables. The third independent layer of longitudinal lines, in indelible color, creates a long lasting color marking between electrical installations and communication systems.

KOUVΙDIS is the first European company investing in the manufacture of double structured wall conduits in small diameters of Ø20, Ø25, Ø32.

This Pan- European Innovation was awarded by the Greek Marketing Academy with the “Innovative Industrial Product” Gold Award



Ideal for concealed type installations in concrete, hollow walls and underplaster.
