== Method ==
Normally a heat gun is used to shrink the sleeving, taking care not to damage nearby areas and to not overheat the sleeving. The heat from a soldering iron can be used, without touching the sleeving. Do not use a direct flame. A hair dryer won't be hot enough.
== Shrink ratio ==
The shrink ratio is the approximate maximum amount the heat shrink tubing will fully shrink compared to its unshrunk diameter. For example, a 3/4" piece with a 3:1 shrink ratio will shrink down to a maximum diameter of approximately 1/4”. Tubing with a larger shrink ratio is more forgiving in fitting, and has a bit thicker wall thickness and slightly less flexibility when shrunk than a lower ratio product.<ref>[http://www.techflex.com/howtos/heatshrink.pdf How to work with heatshrink tubing...], Techflex How-Guide</ref>
