EM Group Heat Shrink Tubing with Adhesive 12/4 mm Black

The EM Group heat shrink tubing with adhesive is a professional-grade solution designed for the reliable insulation and protection of electrical connections. Featuring an internal adhesive lining, this tubing creates a robust, moisture-resistant seal upon heating, which effectively prevents corrosion and protects cables from environmental damage. With a 3:1 shrink ratio, it offers excellent versatility for various cable diameters, ensuring a tight and secure fit that maintains its integrity over time.

Advantages

The primary benefit of this heat shrink tubing is its integrated adhesive layer, which melts during the shrinking process to fill gaps and provide a superior seal against moisture, chemicals, and dust. The 3:1 shrink ratio allows the tubing to accommodate significant variations in cable size, making it highly adaptable for different repair and installation tasks. Its durable material construction ensures long-lasting protection, providing high mechanical strength and electrical insulation for both indoor and outdoor applications.

Suitable for

• Insulating electrical wire splices and connections
• Sealing cable terminations to prevent moisture ingress
• Providing strain relief for cable assemblies
• Repairing damaged cable insulation in automotive and home wiring
• Protecting wires in industrial environments

When it may not be suitable

This tubing is not intended for use in high-temperature environments that exceed its rated operating temperature, as this could compromise the adhesive and the structural integrity of the material. It is also not suitable for applications requiring extreme mechanical abrasion resistance or for use with cables that have a diameter significantly larger than the expanded size of the tubing.

Key specifications

• Shrink ratio: 3:1
• Expanded diameter: 12 mm
• Recovered diameter: 4 mm
• Material: Heat-shrinkable polyolefin with internal adhesive
• Color: Black
• Moisture resistance: High

How to use

To use the tubing, first cut a piece to the desired length, ensuring it covers the area to be protected with some overlap on both sides. Slide the tubing over the cable or connection before making the final electrical joint. Once the connection is prepared, position the tubing centrally over the area. Apply heat evenly using a heat gun, moving from the center toward the ends to allow the adhesive to flow and the tubing to shrink securely around the cable. Allow the tubing to cool completely before handling to ensure the adhesive has set properly.

What to consider before purchase

• Verify that the expanded diameter of 12 mm is sufficient to slide over your specific connector or cable bundle.
• Ensure the recovered diameter of 4 mm will provide a tight fit on your target cable.
• Check the temperature requirements of your specific application.
• Confirm that the environment is compatible with the material properties of the tubing.

Usage recommendations

For the best results, use a professional heat gun with a controlled temperature setting. Avoid using an open flame, as it can cause uneven shrinking, scorching, or damage to the tubing material. Always ensure the surface of the cable is clean and free of oils or debris before application to allow the adhesive to bond effectively.
