Corrugated Protective Conduit Q-Systems QRK 32/50 FLEX NIEB — Ø32/50 mm, flexible, blue

Q-Systems QRK 32/50 FLEX NIEB is a flexible corrugated protective conduit with an inner/outer diameter arrangement of 32/50 mm designed for routing and mechanical protection of electrical cables. The conduit’s flexible construction allows for smooth bending and adaptation to installation geometry while maintaining a protective barrier against mechanical stress and incidental contact in residential, commercial and light industrial environments. Its blue color provides visual identification and differentiation in cable runs.

Advantages

The corrugated design combines flexibility with resistance to crushing and abrasion, enabling easier installation in confined or curved pathways. The conduit supports orderly cable management by keeping conductors bundled and protected from physical damage, dust and local wear. Because of its flexibility and size range, it is suitable for installations requiring frequent routing changes or retrofitting existing cable routes without extensive rework.

Suitable for

• Protection and routing of electrical power and control cables in residential buildings
• Cable management inside commercial premises and office spaces
• Flexible conduit runs in light industrial or workshop environments
• Retrofit projects where existing installations require additional protection or rerouting

Key specifications

• Conduit type: corrugated flexible protective conduit
• Nominal inner diameter: 32 mm (usable conductor space)
• Nominal outer diameter: 50 mm (overall external size)
• Material characteristics: mechanically flexible, abrasion-resistant corrugated wall
• Color: blue for visual identification
• Suitable for indoor installations and protected locations

How to use

Measure the required length and cut the conduit using an appropriate cutting tool to obtain a clean edge. Route the conduit along the planned path, supporting it at regular intervals with compatible clamps or fittings. Insert cables through the conduit using fish tape or by feeding directly, ensuring conductors are not twisted or overly stressed. Use appropriate end fittings, connectors or grommets where the conduit interfaces with enclosures, junction boxes or equipment to secure the ends and maintain mechanical protection.

Usage recommendations

For best results, select conduit supports and fittings that match the conduit outer diameter and intended load conditions. Avoid sharp kinks by maintaining bend radii consistent with the conduit’s flexibility; secure the conduit at intervals recommended by local installation standards. Inspect cable fill limits to prevent overheating and ensure compliance with applicable electrical codes.
