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.
