## Long description

Heat-Shrink Tube Cabletech 3 mm × 1 m black LEC-NAR0245.1 is a single-wall heat-shrink sleeve from Cabletech designed to provide insulation and mechanical protection for small-diameter wires and cable assemblies. With an initial diameter of 3 mm and a 1 m length, this black tube is intended for use where compact, flexible protection and strain relief are required. It is suitable for electrical repairs, protecting soldered joints and connectors, and for improving resistance to abrasion and moisture in confined spaces.
Advantages
The Cabletech heat-shrink tube offers consistent shrink performance and a durable polymer wall that conforms to irregular shapes when heated, creating a tighter profile around cables and joints. Its black color provides discreet appearance and light-blocking properties for visible wiring, while the 1 m length allows multiple cuts to size for different tasks. The tube is lightweight, easy to handle and compatible with common heat sources such as heat guns or a controlled flame when used with appropriate care.
Suitable for
Insulating and protecting soldered wire joints in electronics and hobby projects
Strain relief and bundling of small-diameter cable harnesses in automotive and industrial applications
Repairing damaged cable jackets and protecting connectors from abrasion and moisture
Colour-coding or marking wires when permanent labels are not required
Key specifications
Material type: heat-shrinkable polymer (single-wall)
Nominal pre-shrink diameter: 3 mm
Length: 1 m (continuous tube, cut-to-length)
Colour: black
Shrink ratio: standard for small-diameter single-wall tubing (provides tight fit over wires and joints)
Typical applications: electrical insulation, mechanical protection, strain relief
How to use
Cut the required length from the 1 m tube and slide it over the cable or joint before making the final connection. After positioning, apply heat evenly along the tube using a heat gun set to an appropriate temperature for single-wall tubing until the material uniformly contracts and conforms to the underlying components. Avoid excessive heat concentrated in one spot to prevent damage to insulation or nearby components. Allow the tubing to cool and set before handling.
Usage recommendations
For reliable results, select a heat source that provides controlled, even heat such as a regulated heat gun. When working near heat-sensitive components, shield them or use a lower temperature and longer heating time. Store the tube in a cool, dry place away from direct sunlight to maintain material properties. For outdoor or high-moisture environments requiring higher environmental sealing, consider using adhesive-lined or thicker-walled heat-shrink variants.
