Why should I use HellermannTyton HIS-3 Heat-Shrink Tubing?
HellermannTyton Heat Shrink tubing is optimally matched for providing protection against mechanical, environmental, chemical or electrical effects.

What does a heat shrink ratio of 3:1 mean?
A ratio of 3:1 means when the tube is heated it shrinks to a third of its original diameter.

How can I shrink the tubing?
A heat gun or a heat shrink oven are ideal ways to shrink your tubing. Before heating always check to ensure you know the correct heating temperature of your tubing.

Remember to ensure all health and safety precautions have been taken prior to using a heating devise.

Looking for a quick and easy way to repair a cable jacket? Use this heat shrink tubing from HellermannTyton. It shrinks down to 4mm in diameter, so it's ideal for sealing damaged wires sized between 4 and 12mm. The durable cross-linked polyolefin material withstands impact and abrasion to keep conductors safe in tough environments. While shrinking, the sheath loses just 5% of its length, giving you coverage you can count on. Thanks to a high 20kV/mm dielectric strength, it protects users from electric shocks.

• Flame-resistant and self-extinguishing to minimise the spread of fire
• Halogen-free material doesn't emit toxic smoke when heated
• Can quickly be cut down to size to suit your wiring needs

• Marine industry
• Construction sites
• Manufacturing sector

This component shrinks at temperatures of +100°C or higher, so you can store it without risk of damage.
