Protective Corrugated Conduit Q-Systems QRK 75/25 FLEX blue — flexible corrugated pipe for cable protection

Q-Systems QRK 75/25 FLEX blue is a flexible corrugated conduit designed for safe routing and mechanical protection of electrical and telecommunication cables. The conduit combines flexibility with abrasion resistance to allow easy installation in confined spaces and concealed indoor applications. Its corrugated construction enables repeated bending while maintaining protective coverage for cable runs where movement, tight radii or changes in direction are required.

Advantages

The flexible corrugated design reduces installation time by allowing tool-free bending and fastening around obstacles. Made for indoor and concealed use, this conduit resists abrasion and provides consistent physical protection along the cable length. Its blue color helps with visual identification of communication or low-voltage runs. The construction balances flexibility with sufficient stiffness to support cables without kinking.

Suitable for

• Routing and protecting electrical wiring in concealed indoor installations
• Telecommunication and data cable protection in ducts or behind panels
• Applications requiring flexible bends, tight radii or frequent routing changes
• Mechanical protection where abrasion resistance and repeated bending are needed

Key specifications

• Flexible corrugated construction for enhanced bendability
• Designed for indoor and concealed installation environments
• Provides mechanical and abrasion protection for cables
• Blue color for visual identification of cable routes
• Suitable for multiple cable types used in electrical and telecommunication systems

How to use

Cut the conduit to the required length with an appropriate tool, ensuring a clean edge to avoid sharp burrs. Route cables through the conduit before or after installation depending on access; where necessary, use compatible connectors, couplers or entry fittings to secure connections to junction boxes or equipment. Avoid excessive stretching or compressing of the conduit; maintain gentle bends aligned with the corrugation direction to preserve flexibility and protection. Check that fittings and terminations provide strain relief and that cable fill limits are respected.

Usage recommendations

For indoor concealed installations, pair the QRK 75/25 FLEX conduit with matching entry glands and cable management accessories. Inspect installed runs periodically for signs of compression or abrasion in high-traffic zones and replace sections showing damage. Follow applicable electrical installation standards for cable fill, grounding requirements and fire safety when integrating the conduit into building systems.
