Tubo termorretráctil Hellermann Tyton 380-03002

The HellermannTyton 380-03002 heat shrink tube is a polyolefin tubing designed to provide reliable insulation and protection for electrical connections. With a 3:1 shrink ratio, this multicolour kit conforms tightly to wires and joints when heated, reducing exposure to moisture, dust and mechanical wear. The product combines durability and flexibility for use in wiring, bundling and repair tasks across consumer and industrial environments.

Advantages

The 3:1 shrink ratio ensures a strong, uniform seal over irregular shapes and different cable diameters. Polyolefin construction offers good resistance to abrasion and environmental factors while maintaining flexibility. The multicolour selection simplifies identification and organization of cables. The tubing provides electrical insulation and mechanical protection without adding significant bulk.

Suitable for

• Insulating splices and soldered joints
• Protecting wire ends and terminals
• Bundling and colour-coding harnesses
• Repairing damaged cable sheaths

How to use

Select a tube size slightly larger than the unshrunk wire bundle or connection. Slide the tubing over the joint or wire, then apply heat evenly using a heat gun, hot air tool or other controlled heat source until the tubing shrinks snugly and forms a seal. Allow to cool before handling. Trim excess tubing as needed with appropriate cutting tools.

Recommendations

For best results use a regulated heat gun and keep the heat source moving to avoid overheating any single spot. Choose the correct tubing diameter for the application and inspect seals after cooling to ensure full shrink and adhesion.
