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.

Want a quick and easy way to double-up your cable protection? Use this heat shrink tubing from HellermannTyton. It's made from durable cross-linked polyolefin, which stands up to abrasion and chemicals to safeguard wires in harsh environments. A shrinking ratio of 3:1 means this unit seals tightly around wires as narrow as 8mm. Thanks to a high dielectric strength of 20kV, it also protects users from the risk of electric shocks.

• Holds its shape in temperatures between -55°C and +135°C to suit tough environments
• Length shrinks by just 5% to maximise coverage
• Handy dispenser box lets you cut what you need

• Telecommunications networks
• Hospitals
• Consumer electronics

If your cable has a diameter up to 24mm, the tubing will stop shrinking at the correct width to provide a snug seal.
