The benefits of using heat shrink tubing

When completing DIY electrical projects one of the most popular materials used to insulate wires is heat shrink tubing. This is due to the fact that heat shrink tubing has several advantages over other more traditional materials. It contains fluoropolymers which respond to heat by tightening their fibres, wrapping themselves around wires to provide a secure connection. In this article we will share some of the benefits of heat shrink tubing as well as information about the applications it can be used for.

Heat Shrink Tube

Heat shrink tubing is available in various different types and sizes.

Safe to use

When it comes to wiring work, safety should be your number one priority. You will be pleased to know that heat shrink tubing is a safe material to use to insulate your wires. By insulating your wires properly you will lessen the risk of shorting and electrical fires. Heat shrink tubing also has anti-erosive properties which reduces the risk of damage to wires and prevents further hazards.

Low cost

Heat shrink tubing is very easy to get hold of and is fairly inexpensive. It is also one of the most durable types of wire insulation, meaning that by using it, you can save money in the long run, as you will not need to replace it as often. Unlike other materials, heat shrink tubing does not crack and will not need maintaining regularly, again helping you to cut down on costs.

Excellent insulating properties

With the rising cost of utility bills, many homeowners are doing everything they can in order to make their homes more energy efficient. Heat shrink tubing is one of the most efficient electrical tubing options available. When it comes into contact with heat, the tubing shrinks, creating a close seal around the wires. The tubing has great insulating properties which minimise electrical energy loss as the electricity travels through the wire. Using heat shrink tubing will help you save money on your electricity bills.

Very durable

Heat shrink tubing is extremely durable, such as adhesive line heat shrinkKrempfast LTD and their range. It can withstand high temperatures, as well as dry and moist conditions. Unlike other forms of wire casing, it will not crack or cause the wires to become exposed. Instead it will keep the wires safe, preventing hazards. It lasts significantly longer than other types of wire insulation and is suitable for using in various different areas of the home, including basements and outer walls.


Heat shrink tubing can be used for home DIY electrical projects.

Highly versatile

Due to its excellent insulating properties and durability, heat shrink tubing can be used for a number of different applications. As well as being used for DIY projects in the home, it is also used in the industrial and automotive sectors. Heat shrink tubing comes in a variety of types and sizes, enabling it to meet the needs and requirements of various wiring projects.

Tips for buying heat shrink tubing

In order to get a secure fit, you will need to make sure you choose the right size of heat shrink tubing. To do this you will need to make sure that the tubing’s diameter after shrinking (also known as the recovered diameter) is smaller than the diameter of the area you are planning on insulating. It is equally as important that the tube’s diameter before shrinking (also known as the expanded diameter) is large enough to fit over the area you need to insulate.


If you are completing a DIY wiring project at home, it is important to make sure that your wires are safe and well insulated. One of the best ways to do this is to use heat shrink tubing. Not only is it extremely safe, efficient and durable, but it is also low cost and easy to pick up from your local DIY store.
