## Summary description

Heat-shrink tubing by Cabletech, 3.5 mm diameter and 1 m length in black (model LEC-NAR0246.1). Designed to provide electrical insulation, mechanical protection and strain relief for wires, cable joints and soldered connections. Suitable for DIY electronics, cable repair and wiring harness applications where a compact protective sleeve is required.

## Long description

Heat-shrink tubing Cabletech 3.5 mm × 1 m in black is a flexible polyolefin sleeve designed to shrink uniformly when heated, creating a compact insulating layer around wires and cable joints. The product provides electrical insulation, mechanical protection and strain relief for soldered connections, cable repairs and small wiring harnesses. Its 3.5 mm nominal diameter before shrinking and 1 m length make it suitable for multiple repair or assembly operations in workshops, hobby electronics and professional wiring tasks.
Advantages
The tubing offers consistent heat-shrink performance with good dimensional stability and tight adhesion to irregular shapes after shrinking. Its black colour provides discreet protection and light-blocking for sensitive connections. The material resists abrasion and provides mechanical reinforcement at transition points, reducing risk of wire fatigue and connector failure while maintaining a low-profile finish.
Suitable for
 Insulating soldered joints and exposed conductors in electronics projects
 Repairing damaged cable sheaths and covering splices
 Providing strain relief at connector exits and terminal points
 Bundling small harnesses and identifying protected runs
Key specifications
 Material type: heat-shrink polyolefin
 Nominal diameter before shrink: 3.5 mm
 Length: 1 m
 Colour: black
 Shrink ratio: standard (typical 2:1—designed to conform to irregular shapes after heating)
 Primary functions: electrical insulation, mechanical protection, strain relief
How to use
Cut a suitable length of tubing to cover the exposed area plus a margin on either side. Slide the tubing over the wire or joint before soldering where practical, or position it over the repaired section. Apply even heat using a heat gun, lighter with care, or a soldering iron with a heat-shrink nozzle, moving the heat source along the tubing to ensure uniform shrinking. Continue heating until the tubing has visibly contracted and conforms tightly to the underlying components; avoid overheating that could char adjacent materials.
Usage recommendations
For best results, use a temperature-controlled heat gun set to the manufacturer's recommended range for polyolefin tubing. Ensure surfaces are clean and free of oils or solvents before applying. For strain relief applications, select slightly longer pieces to extend over connector bodies and adjacent cable insulation. When working near heat-sensitive components, shield them or apply heat in short intervals to prevent damage.
