HellermannTyton HIS-3 6/2 mm tubo termorretráctil, negro, 100 mm, 750 uds.

For reliable insulation and strain relief in tight, high-density wiring, this HellermannTyton HIS-3 tubing stands out with its 3:1 shrink ratio — far more versatile than standard 2:1 sleeves. It slides easily over connectors and splices, then shrinks down to a snug, void-free fit even around irregular shapes. The black, cross-linked polyolefin jacket resists abrasion, chemicals, and moisture, while the UL224 VW-1 rating means it self-extinguishes if exposed to flame. Each 100 mm piece is supplied in a bulk pack of 750, ideal for production runs or service kits.

Highlights

• 3:1 shrink ratio recovers from 6 mm to 2 mm for secure coverage over uneven substrates
• Cross-linked polyolefin (POX) delivers excellent electrical insulation and mechanical protection
• Self-extinguishing per UL224 VW-1; 600 V dielectric rating for low-voltage applications
• Wide operating range from -55°C to +125°C, with full recovery at just +90°C
• Supplied as 750 pieces of 100 mm length — ready to use without cutting

In daily use

Cut-to-length tubing often wastes time and material, but these pre-cut 100 mm sleeves are ready straight from the box. The 3:1 ratio means one size can handle multiple cable diameters, reducing inventory. After shrinking, the recovered wall thickness of 0.64 mm gives a tough, uniform barrier against abrasion and light impact. The black finish blends neatly into harnesses and equipment, and the tubing remains flexible even at low temperatures, so it won't crack during cold-weather installation.
