Protective Conduit Pipe Kopos 75/4 HDPE UV-resistant smooth, black, length 3 m

Kopos Protective Conduit Pipe 75/4 is a smooth-walled conduit manufactured from high-density polyethylene (HDPE) with a black UV-resistant finish and a nominal length of 3 m. It is designed to shield electrical cables and wiring from mechanical damage, moisture and corrosion while allowing neat cable routing in indoor and outdoor installations exposed to sunlight. The smooth internal surface facilitates cable pulling and reduces friction, while the UV-stabilised outer layer maintains dimensional stability and surface integrity during outdoor exposure.

Advantages

This HDPE conduit combines mechanical strength with lightweight handling, offering good impact resistance and chemical inertness. The UV-resistant black finish prevents premature degradation and discoloration under sunlight, extending service life in exposed applications. The smooth bore simplifies cable installation and reduces the likelihood of snagging, and the 3 m length minimises jointing for longer continuous runs.

Suitable for

• Protection of electrical and communication cables in outdoor and indoor installations
• Cable routing in residential, commercial and light industrial environments
• Areas where UV exposure or weathering is a concern (façades, rooftop runs, external trenches)
• Applications requiring corrosion-resistant, non-metallic conduits

When it may not be suitable

This HDPE conduit is not intended for use as a structural support or for applications that require metal conduits for grounding or high-temperature resistance. It may deform if exposed to continuous temperatures above the material's rated range or if subjected to heavy point loads without additional mechanical protection.

Key specifications

• Material: High-density polyethylene (HDPE)
• Inner surface: Smooth bore for reduced friction during cable pulling
• Outer finish: UV-resistant black
• Length: 3 m
• Mechanical properties: Good impact resistance and chemical corrosion resistance
• Typical applications: Indoor and outdoor cable protection and routing

How to use

Measure and cut the conduit to the required length using a fine-toothed saw or pipe cutter suitable for plastic. Deburr cut ends to avoid sharp edges. Route the conduit along the planned path, securing with appropriate clips or clamps at regular intervals and at changes of direction. Use compatible couplers or connectors to join multiple lengths and seal entries where necessary to prevent ingress of moisture or debris. When pulling cables, use a lubricant approved for use with HDPE if long runs or multiple bends increase friction.

What to consider before purchase

• Verify conduit internal diameter and wall thickness are suitable for the cables and fill ratio required
• Confirm UV resistance and temperature limits meet the conditions of the installation site
• Check compatibility with available couplers, clamps and fixing systems
• Plan for appropriate mechanical protection where the conduit will be exposed to heavy loads or impact

Usage recommendations

For best results, store coils or straight lengths flat and protected from prolonged direct sunlight before installation. Secure the conduit at recommended intervals, avoid sharp bends beyond the manufacturer’s minimum bend radius, and use approved connectors and seals for outdoor or buried installations to maintain long-term protection of cables.
