Hellermann Heat shrink tube 308-32400 Black 3:1 ratio 3 meters length 24 mm to 8 mm diameter

The Hellermann heat shrink tube is a professional-grade insulation solution designed for reliable cable management and protection. Featuring a 3:1 shrink ratio, this black heat shrink tube adapts securely to varying diameters, transitioning efficiently from 24 mm down to 8 mm. With a total length of 3 meters, it provides ample material for multiple cabling tasks in various technical environments.

Advantages

This heat shrink tubing offers dependable electrical insulation, secure wire bundling, and robust mechanical protection against wear and environmental factors. The high shrink ratio ensures a tight fit over irregularly shaped components, connectors, and splices. Its durable construction maintains performance over time, while the black color provides a clean, professional finish for all installations.

Suitable for

• Electrical insulation of wire splices and connections
• Bundling and organizing cable harnesses
• Mechanical protection for cables in industrial settings
• Providing strain relief at connector junctions

When it may not be suitable

This product may not be appropriate for applications requiring continuous exposure to temperatures beyond standard operating limits or environments demanding specialized chemical resistance. It is also unsuitable for cables or components that exceed the initial 24 mm maximum diameter or require shrinking below the 8 mm minimum limit.

Key specifications

• Color: Black
• Shrink ratio: 3:1
• Length: 3 meters
• Maximum diameter: 24 mm
• Minimum diameter: 8 mm

How to use

Measure the required length of the tube and cut it cleanly, ensuring the piece is slightly longer than the area that needs coverage. Slide the tube over the cable or wire joint before making final connections if necessary. Apply uniform heat using a heat gun or another appropriate heat source, moving continuously along the tube from one end to the other until it shrinks snugly around the object. Allow the material to cool completely before handling or putting the assembly into service.

What to consider before purchase

• Verify that the cable bundle or component diameter falls within the 24 mm to 8 mm range
• Check that the 3-meter length is sufficient for your project requirements
• Ensure you have a suitable heat source available for proper shrinking

Usage recommendations: Store the heat shrink tube in a cool, dry place away from direct sunlight to preserve material integrity prior to installation. Always follow safety guidelines and use proper ventilation when applying heat during the shrinking process.
