Ergom TCR Heat Shrink Tubing 12.7/6.4 mm Black, 10 Pieces

The Ergom TCR heat shrink tubing is a professional-grade solution for electrical insulation, cable protection, and wire bundling. Designed to provide a secure and durable fit, this tubing features a 2:1 shrink ratio, effectively reducing its diameter from 12.7 mm to 6.4 mm when heat is applied. The black finish ensures a clean, professional appearance in any installation, while the material provides robust protection against mechanical stress, moisture, and environmental factors.

Advantages

This heat shrink tubing offers excellent flexibility and high resistance to external conditions, making it a reliable choice for long-term electrical projects. The 2:1 shrink ratio allows for a tight, conforming fit around cables and connectors of various shapes, ensuring that the insulation remains securely in place. Its durable construction helps prevent wire fraying and provides an effective barrier against abrasion, chemicals, and humidity, which significantly extends the lifespan of electrical connections.

Suitable for

• Electrical insulation of wire joints and terminals
• Cable bundling and organization
• Protection of wires against mechanical damage
• Industrial and household electrical repairs
• Color-coding and identification of cable runs

When it may not be suitable

This tubing is not intended for use in environments with extreme temperatures exceeding the material's thermal rating or in applications requiring high-pressure fluid sealing. It should not be used as a primary structural support for heavy cables or in areas exposed to continuous direct flame.

Key specifications

• Shrink ratio: 2:1
• Initial diameter: 12.7 mm
• Shrunk diameter: 6.4 mm
• Color: Black
• Quantity: 10 pieces
• Material: Heat-shrinkable polyolefin

How to use

To use the Ergom TCR heat shrink tubing, first measure and cut the required length of the tubing to cover the area needing insulation. Slide the tubing over the wire or cable connection before making the final electrical termination if necessary. Apply heat evenly around the entire circumference of the tubing using a heat gun or a controlled heat source until it shrinks tightly around the cable. Allow the tubing to cool completely before handling to ensure a secure and permanent bond.

What to consider before purchase

• Ensure the initial diameter of 12.7 mm is sufficient to slide over your specific cable connectors.
• Verify that the final shrunk diameter of 6.4 mm will provide a tight fit on your target wire.
• Confirm the quantity of 10 pieces meets the requirements of your project.
• Check the temperature requirements of your specific application environment.

Usage recommendations

For the best results, always use a dedicated heat gun to ensure uniform shrinkage and prevent localized overheating or burning of the material. Avoid using open flames, as they can cause uneven shrinking and damage the integrity of the tubing.
