Split Corrugated Cable Conduit (Spiral Wire Loom) – Ø4–55 mm, Black Polypropylene

This split corrugated cable conduit made of polypropylene is the ideal solution for organizing and protecting electrical wiring in any marine or automotive setting. Its corrugated profile inside and out gives it excellent flexibility and crush resistance. The polypropylene material is lightweight yet durable – resistant to saltwater, fuel, and chemicals – so it can be used in engine compartments, bilges, and exposed deck areas without degrading or cracking over time. The black color is UV-stabilized to withstand prolonged sun exposure.

The longitudinal split design means you can easily add or remove cables without disconnecting their connectors – simply pry open the tubing and insert the cable, then let the conduit spring back to fully encase the wires. Once in place, the loom grips your cable bundle snugly, shielding it from damage. This makes installing and servicing your electrical system significantly faster and more convenient, even in the hard-to-reach areas of your boat.

Applications & Recommendations:

• Primarily used for boat and yacht wiring installations, including running cables for navigation lights, pumps, fish finders, audio systems, and other electronics. It protects them from mechanical damage when routed through bulkheads, around sharp corners, or in vibrating hull structures.
• Small diameters (4–10 mm) are suitable for single cables or thin bundles – e.g., sensor leads, instrument wires, and LED lighting harnesses behind dashboards of small boats (3–5 meters). We recommend these sizes for compact installations where space is at a premium.
• Medium diameters (13–25 mm) allow grouping several wires together – e.g., the main wiring loom of a mid-sized boat (5–7 meters) carrying power cables for lighting, navigation, and communication systems. These sizes are ideal for running cables along the length of the hull or through the engine room of RIBs and cabin cruisers.
• Large diameters (28–55 mm) are meant for hefty cable bundles or hoses – e.g., the primary harness on larger yachts and motorboats over 7–10 meters, where multiple systems (electronics, engine, batteries) share a common routing path. A conduit of this size provides protection and organization for thick gauge power cables (such as main 12V/24V feeds, windlass cables, solar panel arrays, etc.), shielding them from bending and impact.
• Versatile use: Beyond the marine sector, this protective conduit is also suitable for automotive, industrial, and home applications – anywhere cables need to be neatly organized and shielded. It can be easily cut to the desired length with snips or a sharp knife. For sharp turns or corners, we recommend using specialized corrugated conduit clips/clamps to hold the tubing in place (available separately).
• When installing on exposed decks or outdoors, ensure the conduit is secured at intervals (with zip ties or clamps) so it won’t shift due to wind or vibration. In enclosed spaces (bilges, aft lockers), securing the loom will prevent it from contacting moving parts or hot surfaces. By following these practices, you’ll maintain a tidy, safe, and long-lasting wiring setup on board.
