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 extreme chemical resistance. It should not be used as a primary structural support for heavy cables or in areas where it will be subjected to constant mechanical impact or sharp edges.
Key specifications
Shrink ratio: 4:1
Diameter range: 4mm to 1mm
Color: Black
Material: Heat-shrinkable polyolefin
Application: Electrical insulation and protection
How to use
To use the EM Group heat shrink tubing, first cut a piece of the tubing to the desired length, ensuring it is slightly longer than the area you intend to cover. Slide the tubing over the wire or connector before making your 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. Rotate the tubing as you apply heat to ensure uniform shrinking until it fits snugly around the component.
What to consider before purchase
Ensure the 4mm initial diameter is sufficient to slide over your specific connectors or cable ends.
Verify that the 1mm shrunk diameter will provide a tight enough fit for your wire gauge.
Check the temperature requirements of your specific application to ensure compatibility.
Usage recommendations
For the best results, always apply heat starting from the center of the tubing and move toward the ends to prevent air bubbles or uneven shrinking. Avoid overheating the material, as this may cause it to become brittle or lose its protective properties.
