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 way to keep sensitive cables safely under wraps? Shield them with this heat shrink tubing from HellermannTyton. It's a rugged plastic sheath that boosts protection and bundles wires together. With a 20kV/mm dielectric strength, it ensures your connection is fully insulated to prevent shocks during handling. Thanks to its 3:1 shrink ratio, this tubing reduces from 1.5mm in diameter to 0.5mm, making it ideal for hook up wires and other thin PCB wires.
