Red heat-shrink tubing 4.5mm for professional insulation
Set of 10 red heat-shrink tubes, each 100cm long, ideal for insulating and protecting electrical connections in household or professional installations. Flexible and halogen-free, they shrink uniformly at 90 degrees Celsius, ensuring safe and durable insulation for cables and connectors.
What you get with this product
- Secure insulation of electrical connections without the risk of short circuits or corrosion
- Complete set of 10 tubes, 1 meter each — enough for multiple electrical projects
- Fast and uniform shrinkage using a hair dryer or regular heat gun
- Flexible, halogen-free material, durable over time and safe for indoor environments
- Red color for quick identification in complex installations with multiple circuits
- Reduces original diameter by half for firm attachment to cables of various thicknesses
How it works and how to install
Cut the required length from the tube, slide it over the connection or cable to be insulated, then apply heat uniformly with a hair dryer or heat gun. At 90 degrees Celsius, the tube contracts radially by a minimum of 50%, adhering firmly to the surface and forming a sealed protective layer. The length change is minimal, maximum 5%, so the tube remains precisely where you install it.
Frequently asked questions
Can I use a regular hair dryer or do I need a professional heat gun?
A regular hair dryer at maximum temperature works perfectly for 4.5mm tubes. A heat gun speeds up the process but is not mandatory.
How much does the tube shrink after heating?
The diameter is reduced by a minimum of 50%, so a 4.5mm tube shrinks to approximately 2.25mm, suitable for cables between 1.5-3mm thick.
Is the tube resistant to humidity or outdoor use?
The tube is moisture-resistant and provides good protection, but for long-term outdoor use, additional sealing solutions against UV and weather are recommended.
