Split Tube Conduit

Durable Automotive Split Tube Conduit for Off-Grid Wiring

When building or upgrading the electrical system in a caravan, 4WD canopy, or boat, managing your wiring is crucial for safety and reliability. Black split tube conduit, also known as corrugated split tubing or auto electrical conduit, provides a tough, flexible protective layer over exposed cables. It prevents chafing, short circuits, and environmental damage, ensuring your mobile power system remains secure across corrugated roads and harsh Australian environments.

Why Use Corrugated Split Tubing?

Routing power lines through metal chassis rails, bulkheads, or engine bays exposes them to vibration and abrasion. Automotive flexible conduit is designed to shield these vital connections. The split loom design allows you to easily slip the conduit over existing wire harnesses without needing to disconnect any terminals. This makes it an ideal solution for both new installations and retrofitting cable management into existing off-grid power setups.

Whether you are running heavy-duty power feeds for a dual battery system or protecting thinner lighting wires, wrapping them in automotive cable conduit significantly extends the lifespan of the insulation.

Key Benefits of Our Auto Electrical Conduit

• Abrasion and Impact Resistance: Shields internal wiring from physical damage, rubbing, and sharp edges commonly found in automotive and marine environments.
• Chemical and Heat Defence: Highly resistant to petrol, oil spills, and elevated temperatures, making it safe for use in engine bays and rugged 4WD applications.
• Flexible and Easy to Install: The convoluted tubing bends smoothly around tight corners without kinking, while the full-length slit allows rapid cable insertion.
• Professional Finish: Keeps your electrical installations looking exceptionally neat and well-organised.

Extensive Range of Sizes

To accommodate different wire gauges and harness thicknesses, we supply black split conduit in a comprehensive range of internal diameters (ID). Choose from 7mm, 10mm, 13mm, 16mm, 20mm, 23mm, 29mm, and 36mm ID options.

For small projects or custom cable runs, our conduit is available by the metre. For major builds, commercial workshops, or complete vehicle fit-outs, we offer bulk rolls ranging from 25m up to 200m, ensuring you have plenty of split tube conduit on hand for any size job. To properly complete your cable runs, we highly recommend finishing the ends with heat shrink tubing to prevent the conduit from slipping and to seal out moisture.

Compatibility Notes: Sizing Your Split Conduit

Selecting the correct automotive split conduit size depends on the total outer diameter of the cables you intend to bundle.

Single Cables: When protecting heavy-duty lines like battery cables, ensure the inner diameter of the conduit is slightly larger than the cable's outer jacket to allow for flexibility.

Multiple Cables: For multi-core wiring, such as standard automotive cables, calculate the combined thickness of the bundle. It is best to leave a small amount of extra room inside the corrugated tubing so the wires can flex naturally without binding.

Securing: Use high-quality electrical tape, cable ties, or heat shrink at regular intervals to keep the split closed, particularly in high-vibration off-grid and RV environments.
