Once shrunk, the wiring harness inside the tubing is isolated from any external contamination and protected from freiting and wear.Widely used in competition, in the agricultural sector and on original vehicles, but also in industry.Theuses and applications of heat-shrink tubing are vast:

  • Insulating the weld between 2 electrical wires
  • Protecting a flexible tube or hose of any kind
  • Protecting and sheathing an electrical harness
  • Insulating an electrical connector inlet

Tip: For easier routing and handling, take care to braid your wires inside your sheaths,either using the “mil-spec” method, which is long and tedious but ensures a perfect result,or by twisting the wires by hand, which greatly increases the handling of your sheaths and bundles .
