HellermannTyton HIS-3 Heat Shrink Tubing 12.7/4.2 mm Black, 3:1, 1 m 323-10630

This heat shrink tubing from HellermannTyton's HIS-3 series offers a 3:1 shrink ratio, allowing it to conform tightly over irregular shapes and connectors. The 12.7 mm supplied diameter recovers to 4.2 mm, providing reliable insulation and strain relief for cable joints and terminations.

Highlights

• 3:1 shrink ratio for secure fit over components
• Cross-linked polyolefin construction for durability
• Operating temperature range -55°C to +135°C
• Self-extinguishing per UL224 VW-1
• Good UV and chemical resistance

In daily use

Made from cross-linked polyolefin, the tubing shrinks at a minimum temperature of +90°C and withstands continuous operating temperatures from -55°C to +135°C. The black colour offers good UV resistance, making it suitable for outdoor applications. It provides electrical insulation, mechanical protection, and strain relief for cables and wire bundles.
