What does a heat shrink ratio of 2:1 mean?
A ratio of 2:1 means when the tube is heated it shrinks to half of its original diameter.

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 device.
