Tubo termorretrátil HellermannTyton HIS-PACK 6,4/3,2 mm azul 5 m HIS-PACK-6,4/3,2-BU

The HIS-PACK dispenser box keeps 5 metres of 2:1 heat shrink tubing neatly organised and tangle-free, ready for fast, repeatable insulation work. The blue cross-linked polyolefin sleeve shrinks from 6.4 mm down to 3.2 mm when heated, creating a tight, durable seal around cables, splices and connectors.

Highlights

• 2:1 shrink ratio for secure, uniform coverage
• Cross-linked polyolefin resists abrasion and chemicals
• Operating range from -55 °C to +125 °C
• UL224 VW-1 flame-retardant rating
• Convenient dispenser box for workshop or field use

In daily use

Slide the tubing over the joint, apply heat from a hot air gun, and watch it conform tightly to the underlying shape. The recovered wall provides electrical insulation and strain relief, while the blue colour aids circuit identification. The box dispenses cleanly, so the remaining length stays protected until the next job.
