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.

Get your wires safely under wraps with this heat shrink tubing from HellermannTyton. Its small 3mm diameter shrinks down to just 1mm, so it's ideal for repairs, bundling or jacket protection. Thanks to its durable POX material, this heavy-duty sleeve stays strong and maintains its shape in a broad temperature range of -55°C to +135°C. Shrinking it to size is simple – apply a heat gun at +100°C or hotter until you achieve a snug fit.
