Kopos smooth protective conduit tube 50 x 4.0 mm, HDPE UV-resistant, length 3 m

Kopos smooth protective conduit tube 50 x 4.0 mm is a rigid HDPE tube designed for protecting electrical cables and wiring in exposed and outdoor installations. With an outer diameter of 50 mm and a wall thickness of 4.0 mm, the 3 m length conduit offers continuous protection against mechanical damage and environmental influence. The UV-resistant material ensures long-term performance in sunlight-exposed installations while HDPE provides chemical resistance and low moisture absorption for reliable cable runs.

Advantages

The conduit's smooth internal surface facilitates easy cable pulling and reduces friction during installation. Its rigid HDPE construction combines impact resistance with flexibility sufficient for routing around obstacles. UV stabilisation prevents degradation from prolonged sun exposure, extending service life in external applications. The material's inherent chemical resistance and low water uptake support use in a variety of environments, including damp or industrial locations.

Suitable for

• Outdoor cable protection and surface mounting
• Underground conduit runs where HDPE is permitted
• Protecting power, control and communication cables
• Exposed façades, rooflines and open-air installations

Key specifications

• Material: high-density polyethylene (HDPE)
• Outer diameter: 50 mm
• Wall thickness: 4.0 mm
• Length: 3 m
• Surface: smooth internal and external finish
• UV resistance: stabilised for outdoor exposure
• Properties: impact resistant, chemical resistant, low moisture absorption

How to use

Select conduit runs according to cable fill and local electrical regulations. Cut the HDPE tube to the required length using an appropriate saw or pipe cutter, then deburr the ends to prevent damage to cable insulation. Secure the conduit with compatible clamps or brackets at recommended intervals and ensure watertight transitions where required using appropriate fittings or sealants. When pulling cables, use a lubricant approved for cable installation if necessary to reduce friction along the smooth inner surface.

Usage recommendations

Follow applicable national and local electrical codes when installing conduit and cables. Avoid prolonged contact with petroleum-based solvents that could affect some plastics. For buried installations, confirm local guidance on burial depth and mechanical protection; where additional protection is required, consider burial in sand or use of protective ducting. Inspect installed runs periodically for mechanical damage and UV degradation despite stabilisation.
