Heat shrink tubing kit ORNO OR-AE-13141/B — black thermal sleeves set

ORNO OR-AE-13141/B is a kit of black heat shrink tubing designed for electrical insulation, wire repair and protection. The set contains multiple thermal sleeves of varying diameters and lengths as supplied, made to shrink when heated to form a tight insulating seal. The tubing provides electrical insulation and mechanical protection for cable joints and terminations and is intended for general electrical maintenance, strain relief and corrosion protection.

Advantages

The black heat shrink tubing set offers consistent shrink performance and a close-fitting insulating layer after application. Its construction ensures improved mechanical protection and reduced moisture ingress at joints. The kit format with multiple sizes allows selection of the appropriate sleeve for different cable diameters and repair tasks, reducing the need to cut and splice mismatched materials. The tubing is easy to apply using standard heat sources and provides a neat, professional finish to insulation and repair work.

Suitable for

• Insulating and repairing damaged wire insulation
• Protecting cable joints and terminations from mechanical wear
• Providing strain relief for connectors and cable entries
• Corrosion protection on exposed metal contacts and splices
• General electrical maintenance and hobby electronics projects

Key specifications

• Colour: black
• Material: heat-shrinkable polymer (thermal tubing)
• Contents: multiple sleeves in varying diameters and lengths as supplied
• Shrink action: reduces diameter when heated to form tight insulation
• Primary functions: electrical insulation, mechanical protection, strain relief and moisture/corrosion resistance

How to use

Select a sleeve that fits over the cable or joint before shrinking. Slide the tubing into position covering the area to be insulated or protected, ensuring adequate overlap of components or conductor ends. Apply even heat using a heat gun, lighter with care, or other suitable heat source until the tubing uniformly contracts and conforms to the underlying shape. Allow the tubing to cool to form a firm insulating seal. Trim any excess material for a neat finish.

Usage recommendations

For safe and reliable results use a regulated heat gun and maintain an appropriate distance to avoid overheating adjacent insulation. Verify compatibility with operating temperatures and cable insulation materials before long-term use. For high-voltage, automotive, or permanently installed wiring follow applicable electrical codes and consider professional installation where required.
