Black Heat Shrink Tubing 4.5mm for Professional Electrical Cable Protection
Set of 10 black heat shrink tubes, each 100cm long, ideal for insulating and protecting electrical connections in electronics projects, automotive installations, or household repairs. The flexible, halogen-free material shrinks at 90°C, ensuring a perfect and durable covering for cables.
What you get with this product
- Complete set of 10 tubes, 1 meter each — enough for multiple cable insulation projects
- Rapid shrinkage at 90°C with common heat sources — you can use an industrial heat gun, heat gun, or even a lighter
- Secure protection against short circuits and wear — the shrunk material completely covers exposed connections
- Maximum flexibility after application — the tube remains malleable, does not crack or unravel over time
- Halogen-free material — safe for use in enclosed spaces, does not emit toxic fumes when heated
- 4.5mm unshrunk diameter, suitable for 2-3mm thick cables — check compatibility before ordering
How it works and how to install
Cut the required length of tubing, slip it over the cable or connection to be protected, then apply heat evenly with a heat gun or industrial hair dryer. At 90°C, the tube begins to shrink and perfectly mold to the cable's surface. A radial shrinkage of at least 50% ensures a firm grip, and the length change is a maximum of 5%, so the tube does not deform excessively. Application takes less than a minute per connection.
Frequently asked questions
How much does the tube shrink after heating?
The tube shrinks radially by at least 50%, meaning the 4.5mm diameter becomes approximately 2.25mm or smaller, depending on the thickness of the cable it covers.
Can I use a regular hair dryer for shrinking?
A hair dryer reaches about 60-80°C, which is insufficient for complete shrinkage. We recommend an industrial heat gun or industrial hair dryer that reaches 90-100°C.
Is it safe to use the tubing in automotive installations?
Yes, the material is flexible and resistant to vibrations. Being halogen-free, it does not emit toxic substances at normal engine operating temperatures.
