The Courbi Sibi Super 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.

Suitable for indoor domestic and industrial facilities, concrete box installations, and garden settings. Compatible with junction boxes and SPOT fittings. Purchase price is per metre within a 50m package.

Key Features

• 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

• 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, protecting cable sheaths
• Larger 17mm inner bore compared to the Φ13.5 variant accommodates heavier cable runs
• Compatible with standard junction boxes and SPOT fittings for complete system integration
