HellermannTyton 600-02949 Chloroprene Rubber (CR) Heat Shrink Tubing 4:1 12mm Black 1.2m

The HellermannTyton 600-02949 is a high-performance thick-walled heat shrink tubing made from chloroprene rubber (CR). Designed for demanding applications, it provides excellent electrical insulation, sealing, mechanical protection, and strain relief. With a 4:1 shrink ratio, it fits a wide range of cable diameters and ensures a tight, secure fit. The adhesive lining provides additional sealing against moisture and contaminants.

Advantages

This heat shrink tubing offers superior UV resistance and good chemical resistance to acids, alkalis, and solvents. It is self-extinguishing and operates reliably in temperatures from -40°C to +120°C. The high dielectric strength (>15 kV/mm) and mechanical robustness make it ideal for industrial and outdoor use.

Suitable for

• Electrical insulation and sealing of cables and connectors
• Mechanical protection and strain relief in harsh environments
• Automotive, marine, and industrial applications
• Outdoor installations requiring UV resistance
