## Long description

The EM Group thick-walled heat shrink tubing with adhesive is a high-performance solution designed for reliable electrical insulation and environmental protection. Featuring a 4:1 shrink ratio, this tubing is engineered to provide a secure, tight fit over cables and connectors, while the integrated internal adhesive layer melts during the shrinking process to create a moisture-proof and chemical-resistant seal. With a diameter range of 12mm to 3mm, it is suitable for a wide variety of wiring projects where durability and long-term stability are required.
Advantages
This heat shrink tubing offers exceptional mechanical strength and protection against harsh environmental conditions. The thick-walled construction ensures high resistance to abrasion and impact, making it ideal for demanding applications. The internal adhesive lining provides an excellent seal that prevents moisture ingress and corrosion, ensuring the integrity of electrical connections over time. Its high shrink ratio allows for easy installation over irregular shapes and connectors, providing a versatile and professional finish for both industrial and residential electrical systems.
Suitable for
Insulating electrical cable splices and joints
Providing mechanical strain relief for connectors
Sealing cable entries against moisture and dust
Protecting wiring in automotive and industrial environments
Repairing damaged cable insulation
When it may not be suitable
This tubing is not intended for use in high-temperature environments that exceed the material's thermal rating. It is also not suitable for applications requiring extreme flexibility, as the thick-walled design is relatively rigid once shrunk.
Key specifications
Shrink ratio: 4:1
Diameter range: 12mm to 3mm
Material: Thick-walled polyolefin with internal adhesive
Color: Black
Length: 1 meter
How to use
To use the tubing, first cut a piece to the desired length, ensuring it is slightly longer than the area to be covered. Slide the tubing over the cable or connection. Apply heat evenly using a heat gun, starting from the center and moving towards the ends. As the tubing shrinks, the internal adhesive will liquefy and flow to fill gaps, creating a secure, sealed bond. Allow the tubing to cool completely before handling or applying mechanical stress.
What to consider before purchase
Verify the diameter of your cable to ensure it fits within the 12mm to 3mm range
Ensure you have a heat source capable of reaching the required shrinking temperature
Consider the environmental conditions where the cable will be installed
Usage recommendations
For the best results, ensure the surface of the cable is clean and free of oil or debris before applying the tubing. Always use a heat gun rather than an open flame to ensure even heating and prevent damage to the material.
