How it works and how to install it
Select the appropriate tube from the box according to the diameter of the cable you want to insulate, slide it over the connection you've made, then heat it evenly with a heat gun or lighter. Under the action of heat, the tube shrinks to one-third of its original diameter and adheres perfectly to the cable, while the internal silicone layer melts and completely seals the joint. The process takes under 30 seconds per connection. No expensive tools are needed – a simple household heat gun is sufficient.
Frequently Asked Questions
How water-resistant is this heat shrink tubing?
Thanks to the internal silicone layer that melts and completely seals the connection, the tube becomes 100% waterproof after application, suitable for automotive, outdoor, or wet areas in the home.
Can I use a regular lighter to shrink the tube?
Yes, a lighter works for occasional applications, but a heat gun ensures uniform heating and better results, especially for larger diameters.
How many tubes of each size do I get in the set?
The set contains between 10 and 45 pieces per size, depending on frequent use — the small ones (1.6-2.4mm) are more numerous, the large ones (9.5-12.7mm) are fewer, for a total of 280 tubes.
