Kopos Opto protective conduit in smooth black is a 40×3.7 mm high-density polyethylene (HDPE) duct supplied on a 250 m roll. Designed for mechanical protection and routing of electrical cables and fiber optics, this flexible conduit offers moisture resistance and durability for both indoor and outdoor applications. Its smooth internal surface facilitates cable pulling and reduces friction, while the 40 mm outer diameter and 3.7 mm wall thickness provide a balance of rigidity and flexibility for installation along walls, inside trenches, or within conduits networks.
Advantages
The HDPE construction delivers good impact resistance, chemical resistance and long-term dimensional stability in typical environmental conditions. Supplied as a long 250 m roll, the conduit minimizes joints and speeds up installation on extended runs. The smooth bore supports easier cable installation and reduces the need for additional lubricants. Its moisture-resistant properties make it suitable for damp or exposed environments without significant degradation of performance.
Suitable for
- Cable management and protection of electrical wiring
- Routing and protection of fiber optic cables
- Indoor installations in utility rooms, service ducts and false ceilings
- Outdoor runs in trenches, along facades or within protective ducts
- Infrastructure and construction projects requiring flexible protective ducting

How to use
Measure and cut the conduit to the required lengths using appropriate cutting tools for plastic pipe to ensure clean, burr-free ends. Route the conduit along the planned path, securing it at regular intervals with compatible clamps or straps designed for 40 mm ducts. When joining sections or connecting to fittings, use matching coupling components and ensure joints are aligned to maintain a smooth internal path for cable pulling. For fiber optic installations, check bend radius requirements and avoid sharp turns; for electrical cables, follow applicable electrical codes and separation rules.
Usage recommendations
Store the roll on a flat surface away from direct sunlight and extreme heat to avoid deformation. During installation, maintain recommended minimum bend radii for the contained cables and secure conduits at manufacturer-specified intervals. For outdoor burial, ensure compatible backfill materials and protective layers are used to prevent mechanical damage over time.
