## Summary description

Radpol RCKH1 4/1 MIX heat-shrink tubing is a sleeve for insulation and protection of electrical joints and cables. With a 4 mm nominal diameter and 4:1 shrink ratio, it reduces to provide tight sealing; the adhesive-lined construction adds moisture and abrasion resistance. Suitable for repairing insulation, strain relief, and environmental protection of wiring in electrical installations and automotive applications.

## Long description

Radpol RCKH1 4/1 MIX heat-shrink tubing is a 4 mm nominal diameter, adhesive-lined sleeve designed for insulation and protection of electrical joints, cables and connectors. The tubing features a 4:1 shrink ratio that allows a large initial diameter to contract tightly around different conductor sizes and irregular shapes. The inner hot-melt adhesive provides a moisture-resistant seal and improves abrasion resistance, making the product suitable for both indoor electrical installations and automotive wiring repairs.
Advantages
The 4:1 shrink ratio ensures reliable mechanical support and tight sealing on various cable diameters and joints without requiring additional sealing compounds. The adhesive-lined construction bonds to cable insulation and connector surfaces during heating to form a protective layer that resists humidity and dust. Its nominal 4 mm size and flexible polymer construction offer good conformability around splices, terminals and irregular shapes while also providing electrical insulation and strain relief.
Suitable for
 Insulating and protecting wire splices and solder joints
 Environmental protection of automotive and vehicle wiring
 Strain relief for connectors and cable entries
 Repairing damaged insulation on cables and harnesses
Key specifications
 Nominal diameter: 4 mm before shrinkage
 Shrink ratio: 4:1
 Inner adhesive: hot-melt adhesive lining for environmental sealing
 Material: cross-linked polyolefin (heat-shrink polymer)
 Function: electrical insulation, abrasion and moisture protection, strain relief
How to use
Select a tube section slightly longer than the area to be protected, slide the heat-shrink tubing over the joint or damaged section, then apply heat evenly with a heat gun or regulated heat source until the tubing has fully contracted and the inner adhesive flows to form a continuous seal. Allow the assembly to cool so the adhesive solidifies and the polymer completes cross-linking. Trim excess tubing if necessary and inspect the seal for full adhesion and uniform shrinkage.
Usage recommendations
Heat evenly and avoid direct flame contact to prevent scorching; use a temperature-controlled heat gun and follow recommended heating temperatures for polyolefin tubing. Choose a tubing length that fully covers the joint and extends onto stable insulation for effective strain relief. For outdoor or chemically aggressive environments, ensure the mating surfaces are clean and free of contaminants before shrinking to achieve optimal adhesion and long-term protection.
