## Summary description

Erko RTCK thin-walled heat shrink tubing with an internal adhesive layer provides reliable electrical insulation and environmental protection. Designed for a shrink ratio of 3:1, it reduces from 4.8mm to 1.6mm. Ideal for sealing, strain relief, and protecting wire connections, cables, and components in electrical installations. The adhesive ensures a moisture-proof seal, making it suitable for professional industrial and domestic applications.

## Long description

The Erko RTCK thin-walled heat shrink tubing with an internal adhesive layer is a high-quality solution for electrical insulation and environmental protection. This tubing is engineered to provide a secure, moisture-proof seal for wire connections, cables, and various electronic components. With a shrink ratio of 3:1, it effectively reduces its diameter from 4.8mm to 1.6mm when heated, ensuring a tight fit around the protected area.
Advantages
The primary benefit of this heat shrink tubing is the integrated internal adhesive, which melts during the shrinking process to create a robust, waterproof barrier against moisture, chemicals, and mechanical stress. Its thin-walled construction offers excellent flexibility while maintaining high durability, making it an ideal choice for both professional industrial environments and standard domestic electrical repairs. The material provides reliable electrical insulation, preventing short circuits and protecting sensitive connections from environmental degradation.
Suitable for
Sealing and insulating electrical wire splices
Strain relief for cable terminations
Protecting electronic components from moisture and dust
General electrical maintenance in automotive and household applications
When it may not be suitable
This tubing is not intended for applications involving extreme high-temperature environments that exceed the material's thermal rating. It is also not suitable for high-voltage power transmission lines or situations requiring heavy-duty mechanical abrasion resistance beyond the capabilities of thin-walled insulation.
Key specifications
Shrink ratio: 3:1
Initial diameter: 4.8 mm
Shrunk diameter: 1.6 mm
Material: Thin-walled polyolefin with internal adhesive
Color: Black
Length: 1 meter
How to use
To use the Erko RTCK tubing, cut a piece to the desired length, ensuring it covers the connection area with some overlap on both sides. Slide the tubing over the wire or component before making the connection. Once the connection is secure, position the tubing centrally over the area. Apply heat evenly using a heat gun or a similar controlled heat source, starting from the center and moving towards the ends to allow the adhesive to flow and the tubing to shrink tightly around the object.
What to consider before purchase
Ensure the initial diameter is large enough to slide over the connector or cable bundle
Verify that the shrunk diameter will provide a tight fit on the smallest part of the application
Check the temperature requirements of your specific project
Usage recommendations: Always use a heat gun for uniform heating to ensure the internal adhesive activates correctly and the tubing shrinks without burning or damaging the insulation.
