Heat shrink tube Hellermann Tyton 308-10303

The Hellermann Tyton 308-10303 heat shrink tube is a flexible insulating sleeve designed for electrical and electronic applications. Supplied as a 10 m length, the tubing shrinks from a maximum diameter of 3 mm down to a minimum diameter of 1 mm, forming a tight protective layer around wires, solder joints and small connectors. The product offers mechanical protection, electrical insulation and moisture resistance to improve cable longevity and reduce the risk of short circuits in assemblies and repairs.

Advantages

This heat shrink tube provides consistent and controlled shrinkage for small-diameter wiring tasks, ensuring a neat fit over irregular shapes and connections. Made to industry standards, it delivers reliable dielectric properties and abrasion resistance while remaining flexible after installation. The long 10 m length supports multiple repairs or mass installations without frequent resupply.

Suitable for

• Insulating individual conductors and wire splices
• Protecting solder joints and small connectors
• Identifying and bundling small cable runs
• Repairing damaged insulation on low-voltage wiring

Key specifications

• Length: 10 m
• Shrunk (minimum) diameter: approximately 1 mm
• Expanded (maximum) diameter: approximately 3 mm
• Material: cross-linked heat-shrinkable polyolefin (typical for this product class)
• Shrink ratio: suitable for small-diameter applications
• Typical properties: electrical insulation, abrasion resistance and moisture protection

How to use

Cut the required length from the 10 m roll and slide the tubing over the wire, splice or connector before making the electrical joint when possible. Apply heat evenly using a heat gun, hot air tool or controlled flame at a safe distance until the tube has fully conformed to the underlying shape. Allow the tubing to cool so it contracts and forms a secure insulating layer. For best results, ensure surfaces are clean and free of grease or debris prior to application.

Usage recommendations

Use appropriate heat tools and maintain safe working distances to avoid overheating nearby components. For applications requiring high chemical resistance or extended temperature ranges, verify material compatibility with the operating environment before installation. When insulating live circuits, follow applicable safety standards and disconnect power where possible.
