Hellermann Tyton

Hellermann Tyton Heat Shrink, Terminals & Copper Links

When building a resilient electrical system for a caravan, boat, 4WD, or remote tiny home, the integrity of your connections is just as important as the primary hardware. Hellermann Tyton is globally recognised for engineering high-quality cable management, insulation, and connection solutions. Our curated selection of Hellermann Tyton products provides the essential components required to create safe, moisture-resistant, and ultra durable electrical circuits in demanding off-grid environments.

Create Moisture-Resistant Wiring Joints

Corrosion and vibration are the leading causes of wiring failures in mobile applications. To combat this, we supply a comprehensive range of Hellermann Tyton 3:1 glue-lined heat shrink in both red and black. As the tubing is heated, the internal adhesive melts and flows, encapsulating the underlying wire or cable lug to form an impenetrable barrier against water, dust, and mechanical strain. Whether you are terminating heavy-duty battery cables or protecting sensitive solar wiring, choosing a dual-wall adhesive-lined solution is highly recommended. To learn more about selecting the right tubing diameter, read our technical guide to dual wall adhesive-lined heat shrink tubing.

Robust Copper Links and Insulated Terminals

A high-performing circuit requires secure, low-resistance connections. The Hellermann Tyton range includes pure copper links designed to seamlessly join heavy-duty automotive and marine cables from 10mm² (8 B&S) right up to 70mm² (00 B&S). For a complete breakdown of cable sizing equivalents, review our guide to mm, mm², AWG, and B&S cable measurements.

For lighter gauge wiring, our inventory includes a vast selection of pre-insulated ring terminals and butt splice in-line crimp connectors. Colour-coded in red, blue, and yellow to denote wire gauge compatibility, these terminals are available in multiple stud sizes (from M4 to M10) to easily terminate connections onto busbars, fuses, or distribution blocks. Always ensure you pair these terminals with the correct crimping tools for a secure, long-lasting cold weld.

Common use cases for caravan, RV, marine, 4WD, off-grid, tiny home, commercial, industrial, boats, or truck shoppers

• Marine and Boat Wiring: Utilising 3:1 glue-lined heat shrink to protect tinned copper joints from harsh saltwater environments, preventing creeping corrosion.
• 4WD and Canopy Builds: Terminating auxiliary battery cables with heavy-duty copper links and sealing them against extreme dust, mud, and water crossings.
• Caravan and RV Upgrades: Using pre-insulated ring lugs (M4 to M10) to securely attach 12V and 24V solar cabling to roof-mounted junction boxes or interior distribution boards.
• Off-Grid and Tiny Home Systems: Splicing extended cable runs using secure butt connectors, ensuring consistent voltage delivery to lighting and appliance circuits.
• Commercial and Industrial Trucks: Applying large diameter (24-8mm) adhesive heat shrink over heavy-gauge battery and alternator cables to reduce strain and resist severe mechanical vibration.
