The Best Heat Shrink Hacks Everybody Needs To Know

Every home, job, and family has its own unique set of needs. Things you need to fix, or buy, or try, or do. Luckily, you're capable of handling more than you think. And so is your heat shrink tubing.

Heat Shrink Basics

General purpose heat shrink tubing is hollow on the inside with tough, protective walls outside. You can use heat shrink tubing to create seals, connections, barriers, shields, insulation, and protection around just about anything you can fit into it.

It comes in different diameters from 3/64" to 10". So whether you're fixing something slight or experimenting with something large, there's a size that's perfect for you.

The magic of heat shrink happens when you apply heat to the tubing. This activates it and causes the tubes to reduce in size, uniformly and symmetrically. They cure to cool almost instantly creating a snug, consistent fit around materials that lasts for years.

A Quick "How To" Use It

Once you've got your project or to-do inserted into a sliced tube of heat shrink, it's time for heat. This is best done with a heat gun since they have precise temperature controls and perfectly directed flows of heat that activate all sides of the heat shrink's surface.

If you don't have a heat gun, we can help with that, too. Blow dryers won't work, but a small lighter or handheld torch will do the trick. Just make sure to take your time, keep the flame about four inches away, and rotate your tubing slowly and evenly.

Sizing Up Your Heat Shrink

The amount of "shrinkage" that you get is customizable based on what you need. All heat shrink comes with its own shrink ratio.
  • Larger ratios like 4:1 and 6:1 start bigger and shrink down much smaller. This allows you to fit wide-mouth plugs and bulker cables in at the beginning while providing a neat form-fitting final finish.
  • Smaller ratios like 2:1 and 3:1 will begin 2x or 3x larger than their finished shrink. This allows standard charging cables or electrical cords to slide in before giving them a comfortable, close-fitting finish.

Where Heat Shrink Works

Heat shrink is most commonly used for electrical insulation, protecting connections and joints, repairing cords, bundling wires, sealing cables and terminals, and being an all-around reliable solution for electricians, mechanics, and DIY enthusiasts.

But with its quick, easy application and rough, rugged exteriors, heat shrink is a great solution to help you handle all sorts of tasks.
