HELLERMANNTYTON HIS-A liimapinnoitettu lämpökutistesukan annostelulaatikko 9mm/3mm 3:1 5m läpinäkyvä (308-10903)

For electricians and maintenance technicians working on cable harnesses, connectors, and splice repairs, this dispenser box delivers 5 metres of transparent, adhesive-lined heat shrink tubing in a convenient, tangle-free format. The 3:1 shrink ratio and 9 mm pre-shrink diameter allow the tubing to slide easily over connectors and irregular shapes, then shrink down to 3 mm for a tight, protective seal.

Why choose it

The transparent tubing allows visual inspection of the underlying connection, while the inner adhesive melts during shrinking to create a moisture-resistant, environmentally sealed bond. The box dispenser keeps the tubing clean, organised, and easy to cut to the required length.

Ideal use cases

• Insulating and sealing electrical splices and terminations
• Providing strain relief for cable entries and connectors
• Bundling and protecting wire harnesses in automotive, marine, and industrial environments
• Repairing damaged cable jackets where transparency aids inspection

Good to know

The tubing is made from cross-linked polyolefin, offering good resistance to UV, chemicals, and abrasion. It is self-extinguishing, adding a measure of fire safety in electrical applications.
