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 shrink ratio of approximately 3.6:1, this tubing transitions from a 22mm diameter to 6mm, providing a tight, secure fit around cables and connectors. The integrated internal adhesive layer melts during the heating process, creating a permanent, moisture-resistant seal that protects against corrosion and mechanical stress in harsh industrial and automotive environments.
Advantages
This tubing offers exceptional mechanical durability and long-term reliability due to its thick-walled construction. The internal adhesive lining ensures that the connection remains sealed against water, chemicals, and environmental contaminants, making it ideal for outdoor or underground installations. Its high shrink ratio allows for versatile application across varying cable diameters, while the robust material composition provides excellent resistance to abrasion and impact, ensuring that electrical connections remain protected under demanding operational conditions.
Suitable for
- Electrical insulation of cable joints and splices
- Automotive wiring harness protection
- Environmental sealing of cable terminations
- Repairing damaged cable jackets
- Industrial equipment maintenance and protection
When it may not be suitable
This tubing is not intended for use in environments with extreme temperatures that exceed the material's thermal rating. It is also not suitable for applications requiring high flexibility or thin-profile insulation where space constraints are critical.
Key specifications
- Shrink ratio: 3.6:1
- Initial diameter: 22 mm
- Shrunk diameter: 6 mm
- Length: 1 meter
- Color: Black
- Material: Thick-walled polyolefin with internal adhesive
How to use
To apply the tubing, first ensure the surface of the cable or connector is clean and free of debris. Cut the tubing to the desired length, ensuring it overlaps the area to be protected by a sufficient margin. Slide the tubing over the connection and apply heat evenly using a heat gun or a controlled heat source. Start from the center and move toward the ends to allow the adhesive to flow and air to escape. Continue heating until the tubing has fully shrunk and the adhesive is visible at the edges, then allow it to cool completely before handling.
What to consider before purchase
- Verify that the 22mm initial diameter is sufficient to slide over your specific connector or cable assembly.
- Ensure the 6mm final diameter provides a tight enough fit for your cable gauge.
- Confirm that the application environment does not exceed the temperature limits of the material.
Usage recommendations
For optimal sealing, always ensure the heat source is applied uniformly around the entire circumference of the tubing to prevent uneven shrinkage and to ensure the adhesive activates correctly across the entire surface area.
