EM Group Heat Shrink Tubing 15.9/7.9 mm Black 5/8 inch

The EM Group heat shrink tubing with a 15.9 mm initial diameter is a versatile solution for electrical insulation and cable management. Engineered with a 2:1 shrink ratio, this tubing reduces to a 7.9 mm diameter when heated, ensuring a tight and secure fit around wires, cables, and connectors. Its durable black finish provides a professional appearance while offering robust protection against moisture, abrasion, and environmental stressors in both industrial and home repair settings.

Advantages

This heat shrink tubing offers excellent flexibility and high dielectric strength, making it an ideal choice for insulating electrical joints and terminations. The material is designed to withstand harsh conditions, preventing mechanical damage and corrosion on bundled wires. Its consistent shrink performance ensures that the tubing conforms perfectly to irregular shapes, providing a reliable seal that maintains its integrity over time.

Suitable for

• Electrical insulation of wire splices and terminals
• Cable bundling and organization
• Protection of wires against abrasion and moisture
• Strain relief for cable assemblies

When it may not be suitable

This tubing is not intended for use in high-temperature environments that exceed the material's thermal rating or for applications requiring extreme chemical resistance. It should not be used as a primary structural support for heavy-duty mechanical components.

Key specifications

• Shrink ratio: 2:1
• Initial diameter: 15.9 mm
• Recovered diameter: 7.9 mm
• Color: Black
• Material type: Heat-shrinkable polyolefin

How to use

To apply the tubing, cut a piece to the desired length, ensuring it is slightly longer than the area to be covered. 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 controlled heat source. Move the heat source back and forth until the tubing shrinks tightly around the object and no air gaps remain.

What to consider before purchase

• Ensure the initial diameter is large enough to slide over the connector or cable bundle.
• Verify that the recovered diameter is small enough to provide a tight fit on the underlying wires.
• Check the temperature requirements of your specific application.

Usage recommendations: Always work in a well-ventilated area when heating the tubing. Avoid overheating the material to prevent burning or structural degradation. Ensure the surface is clean and free of oils before application for the best adhesion.
