The heat-shrink sheath, "thermo sheath" for short, is this funny flexible plastic tube which shrinks definitively when heated. Practical, it protects your welds, connections using a simple hair dryer, lighter flame or soldering iron.
By shrinking enough, the thermo sheath can even seal your connection (useful for increasing the range of an extension cord). The most difficult thing is not to forget to slip the end of the thermo sheath before soldering the wires together ;-)

In short, the thermo sheath is to the handyman in electronics what the screwdriver is to the electrician... once tested, difficult to do without!


This assortment offers 3 diameters of commonly used thermo sheath.
We voluntarily offer one meter lengths to avoid wastage. Indeed, there are always losses of use for the products offered in pre-cut sections of 5 to 10cm.
3 meters of heat-shrink sheath represents 30 sections of 10 centimeters... it's a very comfortable quantity for hobbyism. 

  • 1 meter of 1.6mm sheath (0.8mm narrowed to the maximum).
    Ideal for connecting very small sections such as stepper motor, stepper, sensors, insulation on pin-Header, etc. Practical example here
  • meter of 2.4mm sheath (1.2mm narrowed to the maximum).
    More suitable for larger diameter wire (0.3-0.5mm to 0.75mm square, maybe even 1.5mm square).
    Suitable for more powerful motors and solenoids, connection extension for remote sensor (where it is preferable to use a slightly thicker cable to avoid voltage drops).
  • meter of 4.8mm sheath (2.4mm narrowed to the maximum)
    Allows to tackle much larger diameters of wires... or to ensure the sealing of a connection (ex: mouse wire) or the grouping of several wires near a connector.
    Practical example here (near the Molex connector)
