The Courbi Domo Rigid Medium Type conduit protects electrical cables in installations that require increased mechanical resistance. With a compressive strength of 750 N/5 cm at 22 ±2 °C and an impact resistance tested at -5 °C, it suits both indoor and outdoor applications including underfloor, wall-mounted, and concrete-encased routing.

Produced from U-PVC with UV protection, the conduit is self-extinguishing and does not transmit flame. It measures 16 mm outer diameter, 13 mm inner diameter, and is supplied in 3-metre lengths. Classification code 3331 applies. Sold per metre at the single-piece (3 m) price, packaged in 30-metre bundles.

Key Features

• Rigid U-PVC construction: outer diameter 16 mm, inner diameter 13 mm
• Compressive strength: 750 N/5 cm at 22 ±2 °C (medium mechanical load rating)
• Impact resistance: 2 kg mass from 100 mm drop height at -5 °C
• Self-extinguishing — does not transmit flame
• UV-protected surface for outdoor and exposed installations

Product Benefits

• Medium 750N rating handles construction-site mechanical loads without deforming
