Ergom TCREL Flexible Thin-Walled Heat Shrink Tubing 12.7/6.4 mm Black 7m

The Ergom TCREL flexible thin-walled heat shrink tubing is a high-quality solution for electrical insulation and mechanical protection of cables and connectors. Designed with a 2:1 shrink ratio, this tubing effectively conforms to the shape of the underlying substrate when heated, ensuring a tight and reliable seal. The black finish provides a professional appearance while offering resistance to environmental factors, making it an essential component for organizing and safeguarding electrical wiring systems in both industrial and residential settings.

Advantages

This heat shrink tubing stands out due to its excellent flexibility, which allows for easy installation even in tight spaces or around complex cable geometries. The thin-walled construction ensures that the final assembly remains lightweight and compact without adding unnecessary bulk. Its high-quality material composition provides consistent performance, ensuring that the insulation remains intact over time, effectively preventing short circuits and protecting against abrasion or moisture ingress.

Suitable for

• Electrical insulation of wire splices and terminals
• Cable bundling and organization
• Strain relief for connectors and cable entries
• Color coding and identification of wiring
• General repair and maintenance of electrical equipment

When it may not be suitable

This tubing is not intended for use in high-temperature environments that exceed its thermal rating or in applications requiring heavy-duty mechanical protection against sharp edges or high-impact forces. It is also not suitable for direct burial or underwater applications where a hermetic, waterproof seal is strictly required.

Key specifications

• Shrink ratio: 2:1
• Expanded diameter: 12.7 mm
• Recovered diameter: 6.4 mm
• Material: Flexible polyolefin
• Color: Black
• Length: 7 meters

How to use

To use the Ergom TCREL tubing, first measure and cut the required length to cover the area needing insulation. Slide the tubing over the wire or connector before making the final connection. Once positioned, apply heat evenly using a heat gun or a similar controlled heat source, moving along the length of the tube until it shrinks tightly around the cable. Allow the tubing to cool completely before handling to ensure the material has fully set and achieved its maximum structural integrity.

What to consider before purchase

• Verify the diameter of your cables to ensure the 12.7 mm expanded size is sufficient for your application.
• Ensure the 6.4 mm recovered diameter provides a tight enough fit for your specific wire gauge.
• Check the environmental conditions of your project to ensure standard polyolefin is appropriate.

Usage recommendations

Always use a heat gun with adjustable temperature settings to prevent overheating or burning the tubing. Ensure the area is well-ventilated during the shrinking process to avoid inhaling any potential fumes.
