Tadpol electrical corrugated conduit 25/19 mm with pilot, model RK104, 25 m black

Tadpol electrical corrugated conduit RK104 (25/19 mm) in black is a flexible plastic tubing supplied as a 25 m roll for routing and protecting electrical cables. The conduit is designed with corrugated walls to combine bendability and mechanical protection, and it includes an integrated pilot (pulling cord) to simplify cable installation through long runs and around corners. Intended for indoor and protected outdoor applications, this conduit is suitable for residential, commercial and light industrial wiring where a flexible protective raceway is required.

Advantages

The corrugated construction provides flexible bending without kinking while maintaining resistance to mechanical impact and abrasion. The built-in pilot (pulling cord) reduces installation time and effort by allowing cables to be drawn through the conduit without separate fish tape. Supplied as a continuous 25 m roll, the conduit enables clean, uninterrupted runs and reduces the number of joints. The black color offers UV resistance appropriate for protected outdoor locations and a discreet appearance in visible installations.

Suitable for

• Routing and protecting power, signal and data cables in residential buildings
• Electrical installations in commercial premises and offices
• Light industrial environments where flexible conduit is needed
• Protected outdoor runs such as under eaves or in shelters
• Retrofit and renovation projects requiring flexible cable pathways

How to use

Measure and cut the conduit to the required length using appropriate cutting tools, ensuring clean, square ends. If needed, deburr the cut edges. Use the integrated pilot to attach cable bundles or individual conductors securely, then pull them through the conduit while guiding the tube into position. Where connections to boxes, fittings or gland entries are required, use compatible conduit fittings and clamps to secure the ends and maintain mechanical protection. Avoid sharp kinks and secure the conduit at regular intervals to prevent sagging.

Usage recommendations

For best results, match conduit diameter to the cable bundle size to maintain adequate fill ratio and easier pulling. Use proper strain relief and compatible fittings at terminations. Avoid prolonged exposure to direct sunlight in unprotected outdoor locations; use weatherproof routing or additional protection if exposed. Follow applicable electrical codes and standards when installing.
