The three-layer DUROFLEX PLUS Φ25 conduit by Kouvidis is an innovative choice for electrical installations requiring a combination of flexibility, durability, and safety. It features an external ringed surface for enhanced mechanical strength and a smooth internal surface that facilitates cable passage. The third layer adds indelible color coding for the separation of high and low voltage currents.

Thanks to its composition, it provides excellent protection against ultraviolet radiation, is halogen-free, low smoke emitting, and offers up to 50% reduced friction for easier routing. Combined with the straight DUROSOL PLUS conduit and compatible accessories (couplings, supports, fittings, junction boxes), it forms a complete conduit system for a variety of applications.
