The three-layer DUROFLEX PLUS Φ25 conduit by Kouvidis is an innovative choice for electrical installations that require a combination of flexibility, durability, and safety. It features an external corrugated surface for enhanced mechanical strength and an internal smooth surface that facilitates cable routing. The third layer adds permanent color marking for the separation of power and low voltage circuits. Thanks to its composition, it provides excellent protection against ultraviolet radiation, is halogen-free, low smoke emission, and offers up to 50% reduced friction for easier cable pulling.

Compatible with the straight DUROSOL PLUS conduit and corresponding accessories (couplings, supports, glands, junction boxes), it forms a complete conduit system for a variety of applications.
