Product Description

Generic Flexible Tube PVC (Corrugated Flexible Conduit) is a heavy-duty electrical conduit featuring a corrugated design that provides exceptional flexibility while maintaining crush resistance for demanding installations. Unlike rigid conduit that requires multiple fittings and joints, this flexible tube can be hand-bent around corners and obstacles, significantly reducing installation time and complexity.

The corrugated structure delivers superior crush resistance, making it ideal for underground cable installations, areas subject to mechanical stress, and applications where rigid conduit is impractical. Available in 19mm (50-metre roll) and 25mm (25-metre roll) sizes with grey, black, and white color options, this flexible conduit offers weather resistance, chemical resistance, and long-term durability for residential, commercial, and industrial electrical projects.

Recommended Applications

• Underground Cable Installation: Direct burial applications with superior crush resistance
• Mechanical Stress Areas: Locations subject to vehicle traffic, heavy loads, or impact
• Residential Wiring: Flexible routing around obstacles in homes and apartments
• Commercial Buildings: Office spaces, retail stores requiring flexible conduit solutions
• Industrial Facilities: Factories and warehouses with complex routing requirements
• Outdoor Installations: Weather-resistant for exposed or buried outdoor wiring
• Renovation Projects: Retrofitting electrical systems where rigid conduit is impractical

Installation Guidelines

FAQs

1) What is the difference between flexible and rigid conduit?

Flexible conduit can be bent by hand around corners and obstacles without fittings, ideal for complex routing. Rigid conduit requires elbows, couplers, and precise measurements for direction changes. Flexible conduit saves installation time but rigid conduit offers superior impact protection for exposed installations.

2) Can I bury flexible PVC conduit underground?

Yes, heavy-duty corrugated flexible conduit is designed for direct burial. The corrugated structure provides excellent crush resistance against soil pressure and surface loads. Follow local electrical codes for burial depth (typically 450-600mm for residential). Use appropriate warning tape above the conduit for future excavation safety.

3) How do I connect flexible conduit to junction boxes or fittings?

Use flexible conduit adapters or glands specifically designed for corrugated tube. These fittings grip the corrugations and provide watertight seals. For underground installations, use waterproof glands. Secure with hose clamps if needed for extra holding power in high-stress applications.

4) What is the minimum bending radius for flexible conduit?

Minimum bending radius is typically 6-8 times the conduit diameter. For 19mm conduit, maintain at least 120mm radius; for 25mm, at least 150mm radius. Tighter bends restrict cable pulling and may damage wire insulation. For tight spaces, use smaller diameter conduit or rigid elbows.

5) Can I use flexible conduit for outdoor exposed installations?

Yes, PVC flexible conduit is weather-resistant and suitable for outdoor use. However, for prolonged UV exposure, black conduit offers better UV resistance than grey or white. Secure properly to prevent wind damage and support at regular intervals to prevent sagging. Consider UV-stabilized variants for maximum outdoor durability.

6) How many cables can I run through flexible conduit?

Follow NEC/IEC conduit fill guidelines (maximum 40% fill). For 19mm conduit: 3-4 cables of 1.5 sq.mm or 2-3 cables of 2.5 sq.mm. For 25mm conduit: 5-6 cables of 1.5 sq.mm or 4-5 cables of 2.5 sq.mm. Always leave space for heat dissipation and easy cable pulling.

7) What are the advantages of corrugated vs smooth flexible conduit?

Corrugated conduit offers superior crush resistance and flexibility, ideal for underground and mechanical stress areas. Smooth-wall conduit provides easier cable pulling with less friction, better for long runs or frequent cable changes. Choose corrugated for protection, smooth for cable management.
