Very easy. Time Required. Use this guide to learn how to use heat shrink tubing to repair frayed sheathing on a wire or cable. Measure the diameter of the wire, and then choose a piece of heat shrink that will be large enough to slide onto the wire before heating but will still provide a snug fit once heated. The shrunken diameter should be slightly smaller than the wire's diameter to ensure a tight fit.
Heat shrink tubing has a shrink ratio that dictates how much the tubing will shrink once heated, so it's important to choose the right ratio for the job. For example, a length of ratio tubing with a diameter of 2 mm will shrink to a diameter of 1 mm.
Measure a length of heat shrink tubing that is slightly longer than the damaged section of wire. Keep the heat gun moving back and forth along the length of tubing, as staying in one place can damage the wire even further.
Cancel: I did not complete this guide. Badges: Hold the iron close to, but not touching the wrap. You may have to apply heat to multiple sides of the wrap, as the convection may not evenly reach all sides of the wrap. Not a great solution, but works if no better sources are available. If you let the flame touch the wrap, you can end up with soot depsoited on it.
Soot will wipe off easily, but it is what website can i watch the superbowl for free to burn the wrap and wire, even setting the insulation on fire, if you are careless and let the flame sit too long in one spot or for too long.

Learn more Heat shrink tubing, also known as a shrink sleeve, can be used to repair and insulate wires and cables. You can also use heat shrink tubing around your home to repair other items, such as frayed shoelaces or broken glasses.
Tip: Make sure the tubing has a large enough diameter so you can slide it over any wires or connections to guide it into place. Tip: Label the heat shrink tubing with the size of the tool so you can see it easily from a distance. That way, you can avoid sifting through your tools to find the right size.

Look on the packaging to find the diameter of the tube before shrinking it as well as the shrink ratio it has, which is usually between and Divide the diameter of the shrink tubing by the first number in the ratio to find its shrunken diameter. Calculate which tubing will shrink to a size smaller than the diameter of your wire to ensure that it has a tight seal.
You can buy heat shrink tubing from hardware stores or online. Get heat shrink tubing that matches the color of your wire if you want it to blend in more. Use a pair of scissors to cut the tubing to size. Slide the tubing onto the cable to cover the section you need to insulate. Once you cut the tubing to size, feed the end of the wire through the middle of the tubing.
Heat the tubing with a heat gun so it shrinks around the wire. Hold a heat gun about 3—6 inches 7. Move the nozzle of the heat gun back and forth along the length of tubing so it starts to shrink. Rotate the wire so you can heat all sides of the tubing evenly to make sure it shrinks to size and that there are no air bubbles inside.
Continue heating the tubing until its tight against the wires underneath it. Hair dryers may not be hot enough to make the tubing shrink, but you can try using one on the highest heat setting.
The shrinking temperature for the tubing can usually be found on the packaging. Let the tubing cool completely before you apply any stress to it. Leave the tubing for about 5 minutes so it has a chance to cool around the wire. Method 2 of Slide the tubing over the headphone jack so it overlaps where the headphone cord comes out of the base.
Heat the tubing over the headphone jack to shrink it in place and make a more rigid connection. Prevent shoelaces from fraying by sealing the ends in shrink tubing.
Aglets, the plastic ends on shoelaces, prevent your shoelaces from falling apart, but they may break off over time. Fix broken glasses frames with heat shrink tubing. Hold the broken glasses arm against your frames and guide the tubing over the joint. Use your heat gun to shrink the tubing so the glasses arm stays in place. Add heat shrink tubing to keys to identify them easier. Get multiple colors of heat shrink tubing that are large enough to fit over the largest ends of your keys. Slide the tubing over the key and use a heat gun or another heat source to shrink it.
Once the tubing is tight around your key, use a small screwdriver to poke a hole through in the tubing so you can still put the key on a ring. Use a different color for each key so you can easily find the one you need quickly. Put heat shrink tubing on tool handles so you can get a better grip on them.
