Ergom TCREL Flexible Thin-Walled Heat Shrink Tubing 9.5/4.8 mm, Black, 8m

The Ergom TCREL flexible thin-walled heat shrink tubing is a professional-grade solution for electrical insulation, cable protection, and wire identification. Engineered with a 2:1 shrink ratio, this tubing effectively conforms to the shape of cables and connectors when heated, providing a secure and durable seal. The 9.5/4.8 mm diameter range makes it versatile for various wire gauges, while the black finish ensures a clean, professional appearance in any installation. Packaged in a convenient 8-meter box, it is designed for easy storage and efficient dispensing during electrical work.

Advantages

This heat shrink tubing offers excellent flexibility, allowing it to be used in tight spaces without cracking or losing its protective properties. Its thin-walled construction provides a lightweight yet robust barrier against mechanical damage, moisture, and environmental factors. The high-quality material ensures long-lasting performance, maintaining its integrity over time even in demanding conditions. The box packaging prevents tangling and keeps the tubing clean and organized until the moment of use, which significantly improves workflow efficiency for both professional electricians and hobbyists.

Suitable for

• Electrical insulation of wire splices and terminations
• Cable bundling and organization
• Mechanical protection for connectors and terminals
• Color-coding or identification of electrical circuits
• DIY home electronics and automotive wiring projects

When it may not be suitable

This tubing is not intended for high-temperature environments that exceed its thermal rating or for applications requiring heavy-duty abrasion resistance, such as direct burial or extreme industrial wear. It should not be used as a primary structural support for heavy cables.

Key specifications

• Shrink ratio: 2:1
• Diameter before shrinking: 9.5 mm
• Diameter after shrinking: 4.8 mm
• Material: Flexible polyolefin
• Color: Black
• Total length: 8 meters

How to use

To use the Ergom TCREL tubing, first measure and cut the required length to cover the area needing protection. Slide the tubing over the wire or connector before making the electrical connection. Once the connection is secure, position the tubing over the joint and apply heat evenly using a heat gun or a similar heat source. Move the heat source continuously around the tubing to ensure uniform shrinking until it fits snugly against the cable. Allow the tubing to cool completely before handling the connection.

What to consider before purchase

• Ensure the 9.5/4.8 mm diameter range is compatible with the size of your cables and connectors.
• Verify that the operating temperature of your application is within the limits of standard polyolefin heat shrink.
• Consider if the 8-meter length is sufficient for the scale of your project.

Usage recommendations

Always ensure the surface of the cable is clean and free of oils or debris before applying the tubing to achieve the best adhesion and sealing results. Avoid overheating the material, as this may cause it to become brittle or burn.
