The EM Group RCK 6/2-C heat shrink tubing is a professional-grade solution designed for reliable electrical insulation and cable protection. Featuring an integrated internal adhesive layer, this tubing provides a robust seal that prevents moisture, dust, and chemicals from reaching sensitive connections. With a versatile 3:1 shrink ratio, it conforms tightly to various cable diameters and irregular shapes, ensuring a secure and long-lasting fit for both industrial and domestic wiring projects.
Advantages
The primary benefit of this heat shrink tubing is its dual-wall construction, which combines a flexible outer jacket with a heat-activated adhesive lining. Upon heating, the adhesive melts and flows to fill gaps, creating a moisture-proof barrier that significantly enhances the durability of cable splices and terminations. The material is highly resistant to environmental stressors, providing excellent mechanical strain relief and electrical insulation that maintains its integrity over time. Its black finish offers a clean, professional appearance suitable for visible wiring installations.
Suitable for
- Electrical insulation of wire splices and connections
- Protecting cables from moisture, corrosion, and chemical exposure
- Strain relief for cable terminations
- Repairing damaged cable insulation
- Organizing and bundling wires in automotive or industrial settings
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 should not be used for high-voltage power transmission lines or applications requiring specialized fire-resistant or halogen-free materials.
Key specifications
- Shrink ratio: 3:1
- Internal diameter before shrinking: 6 mm
- Internal diameter after shrinking: 2 mm
- Material: Polyolefin with adhesive lining
- Color: Black
How to use
To use the EM Group RCK 6/2-C tubing, first cut a piece of the desired length, 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 a controlled heat source, apply heat evenly around the tubing, starting from the center and moving toward the ends. Continue heating until the tubing has fully shrunk and the adhesive can be seen slightly emerging from the edges, indicating a proper seal. Allow the connection to cool completely before handling.
What to consider before purchase
- Ensure the 6 mm initial diameter is sufficient to slide over your specific connector or cable bundle.
- Verify that the 2 mm final diameter provides a tight enough fit for your wire gauge.
- Confirm that the heat source available is appropriate for the material's activation temperature.
Usage recommendations: Always ensure the surface of the cable is clean and free of oils or debris before applying the tubing to ensure the adhesive creates a strong, permanent bond.
