When it comes to using heat shrink tubing, it is important to correctly use it to ensure that your application will properly be installed according to your needs. Here are some simple tips when using heat shrink tubing.
How To Use Heat Shrink Tubing Properly.
- One of the first things that you need to do is measure the exposed joint length which needs to be covered by the tubing. When you have properly measured your exposed joint it is wise to add another 1 inch to either side of it to get a proper fit and an overall length. For example: if your joint is roughly 1″ in length then you will have a total of 3″.
- Take some sharp scissors and cut the tubing needed to the length required. When you have cut it simply slide the piece of tubing over the wiring that need to be joined together by either soldering or twisting the wiring together. Please note: do not have your shrink tubing near any heat source, especially when soldering as this may cause your tube to shrink prematurely.
- Once you have connected the wiring, simply slide the tubing over the finished joint once it is cooled (if soldered). Then centre it over the electrical connection and wiring so it is even on both sides.
- Next take your heat gun and plug it in allowing it to warm up. Once it is ready carefully place it near the tubing running it back and forth until the tubing has shrunk around the wiring. Please note: If smoke arises when heating the shrink tubing pull the heat gun back slightly to reduce burning of the tube.
- Lastly you will need to let the heat shrink tubing cool before wrapping a continuous round of electrical tape around the tube covering one end to the other. When wrapping it around simply start about ½ an inch from the shrink tubing on the wire so it can create a water right application with a good mechanical sealing solution.
So if you are looking to use heat shrink tubing with your application, why not follow these simple tips to create the perfect tight seal and cover for your wires each and every time.

Whether you’re a professional or just a DIYer, it can be a great asset for you to have electrical tape in your toolbox at all times. Electrical tape is designed to be used for a variety of demanding and challenging uses which can be anything from protecting water pipes to repairing minor electrical wiring damage. However there are times when this special tape should and shouldn’t be used and here are some tips on where best use your electrical tape to help make your job easier.
Don’t Use Electrical Tape as a Replacement for Wire Nuts
It is important when using electrical tape on electrical wiring such as light switches, outlets, and junction boxes that the tape is used as a temporary measure and not a permanent measure. The reason for this is that with close contact to bare wiring the tape may heat up causing it to degrade over time. This can be problematic especially if it is in contact with something associated with you or your family members. To make sure your family is protected at all times it is best to substitute electrical tape with wire nuts for permanent installations.
Use Only on Minor Cord or Wire Damage
Electrical tape can be used to repair minor wire or cord damage, although it shouldn’t be used if there are frays, cracks or exposed bare electrical wiring. If you have cords that have a nicked or cracked outer sheath but the inner insulation is intact then you may use electrical tape for a safer repair. If the electrical wiring is exposed it may cause the electrical tape to heat up causing a fire hazard. It is also advisable not to cover the electrical tape with flammable materials such as cloths or rugs to also reduce a fire hazard.
Stretch the Tape as You Wrap
When applying electrical tape it is important to wrap it around the object properly to ensure that it works accordingly to how you need it to. To apply correctly it is designed to be stretched slightly allowing for it to adhere better to the object you are wrapping. Applying it loosely may cause complications with insulation protection leading to wire exposure.
Spray With Dielectric Spray
Spray the electrical tape with a clear coat enamel or another selected dielectric spray. This spray can help to protect the tape better and is able to provide increased insulation properties. When applying this spray it is important to turn off the power supply to the cabling until the spray is cured or dried.
