## Long description

The Erko RTCK\_24-8-C/1 is a high-quality, thin-walled heat shrink tubing designed for professional electrical insulation and cable protection. Featuring an integrated internal adhesive layer, this tubing ensures a secure, moisture-resistant seal once heat is applied. With a 3:1 shrink ratio, it is engineered to accommodate a diameter range from 24mm down to 8mm, making it a versatile solution for various wiring projects.
Advantages
The primary benefit of this heat shrink tubing is its dual-wall construction, which combines a flexible outer jacket with a meltable inner adhesive. This combination provides excellent mechanical strain relief and environmental protection against moisture, chemicals, and dust. The 3:1 shrink ratio allows for easy application over irregular shapes and connectors, ensuring a tight fit that maintains its integrity over time. Its black finish provides a clean, professional appearance while offering resistance to UV radiation and general wear.
Suitable for
Electrical insulation of wire splices and terminations
Cable bundling and organization in industrial environments
Providing moisture-proof seals for outdoor wiring
Mechanical strain relief for cable connections
Repairing damaged cable insulation
When it may not be suitable
This tubing is not intended for use in environments with extreme, continuous high-temperature exposure that exceeds the material's thermal rating. It is also not suitable for applications requiring high-pressure hydraulic sealing or structural load-bearing support.
Key specifications
Shrink ratio: 3:1
Diameter range: 24mm to 8mm
Material: Thin-walled polyolefin with internal adhesive
Color: Black
Length: 1 meter
How to use
To use the Erko heat shrink tubing, first cut the required length from the 1-meter piece, ensuring it is slightly longer than the area to be covered. Slide the tubing over the cable or connection point. Using a heat gun or another appropriate heat source, apply heat evenly around the circumference of the tube, starting from the center and moving toward the ends. As the tubing shrinks, the internal adhesive will melt and flow, creating a secure, sealed bond. Allow the material to cool completely before handling or applying mechanical stress.
What to consider before purchase
Ensure the 24mm to 8mm diameter range is compatible with your specific cable or connector size
Verify that the heat source available is sufficient to activate the adhesive
Confirm the length required for your project exceeds the 1-meter supply if necessary
Usage recommendations
For the best results, always clean the surface of the cable or connector before applying the tubing to ensure the adhesive bonds correctly. Avoid overheating the material, as this may cause it to become brittle or lose its protective properties.
