The Courbi Sibi Wire Φ16 is a semi-flexible corrugated conduit produced from U-PVC (outer) with a P-PVC inner lining, in a grey-orange colour. It is intended for medium mechanical-demand electrical installations, including concrete box recesses and garden installations, where standard light-duty conduit provides insufficient protection.

A pre-installed galvanised steel wire guide (Ø 0.8mm, 700/810N/mm²) runs inside the conduit to enable quick and easy cable pulling without separate tools. It is available with a special socket for fast connection, and is compatible with standard junction boxes and SPOT fittings. Purchase price is per metre within a 50m package.

Key Features

• Integrated galvanised steel wire guide (Ø 0.8mm) for rapid cable installation without additional pull wire
• Semi-flexible corrugated (spiral) construction handles light and medium mechanical loads over 500N
• Material: U-PVC outer pipe with P-PVC inner lining — self-extinguishing, does not transmit flame
• Outer diameter D1: 22.8mm; inner diameter D2: 17mm
• Compressive strength: 500N/5cm at 22±2°C
• Impact resistance: 2kg mass from 100mm drop height at -15°C
• Compliant with EN 61386-1/2004, EN 61386-22/2004, and DIN 49018 (dimensions)

Product Benefits

• Pre-installed steel wire guide eliminates the separate step of threading a pull wire, saving installation time
• 500N/5cm compressive strength withstands concrete-pour and medium mechanical loads beyond light-duty conduit
• Impact resistance tested at -15°C ensures reliable performance in cold concrete or outdoor garden settings
• P-PVC inner lining reduces friction during cable pulling, preventing sheath damage
• Available with a special socket for quick and easy conduit-to-fitting connections
