Use the best heat shrink tubing to help securely connect wires
While using electrical tape and ties can help create safer electrical connections, some people have difficulty connecting wires even when using multiple layers of adhesive. This is where heat shrink tubing comes in handy. Used as a versatile plastic coating that DIYers and professional electricians alike can easily apply to cables, these products can also help organize wires for a neater connection. Shrink tubing is a marine-grade product that allows you to put wires underground without worrying about water damage. In addition, they melt evenly to seal the wire, creating a waterproof connection that can withstand tears and abrasion, providing you with a stronger connection.
Using heat-shrink coated and insulated wire is easy, but you need to choose the right product to help prevent mistakes and accidents. With that in mind, we've compiled a list of some of the top heat shrink tubing in 2022 to help you find the ideal choice for your unique needs and job.
Choosing the right heat shrink tubing should depend on the specific job you're trying to perform. For example, when you are installing oil tubing in a pump connection or boat, you need to use marine grade tubing that is water resistant. Durable and strong tubing is ideal for RV electrical repairs because it can withstand a lot of vibration. You can also find heat shrink tubing in a variety of colors and sizes, which helps to mark circuits. And, some tubes are available in maximum lengths of 4 feet, offering some great value. But there are several different variables and factors you should check before choosing a product. So, let's break down the factors you should consider when buying heat shrink tubing. This should help you find something to create a reliable and secure electrical connection.
You should ask yourself if the diameter of the heat shrink tubing is sufficient to cover the terminals you are using. When purchasing some tubing for connecting wires, you should first measure the length of the terminals you are using.
Since the number of heat shrink tubing packages varies, you should choose the product that meets your requirements. For example, a pack of 720 pieces can help you with larger electrical tasks, such as setting up a wired network throughout the house or working on a large server. On the other hand, a 275-piece set is perfect for general electrical work, such as patching, soldering, insulating and grouping.
The second thing to consider is whether the shrink wrap diameter matches the diameter of the wires you need to cover. You should also consider if the product is flexible enough to bend the wire after installation. You can find heat shrink tubing in a variety of shrink ratios, but the most common are 2:1, 3:1 and 4:1.
It's usually best to go with 3:1, which shrinks to about one-third of the original size and can handle a variety of wire sizes. Although thinner than tubing with a 4:1 shrink ratio, it retains more flexibility, which aids in installation.
Check that the package contains a sufficient number of pieces and colors to meet your requirements. This will come in handy if you are dealing with different installations regularly, especially if you are naming connections. However, when the circuit you are dealing with is already clearly outlined, the color becomes less important.
Most heat shrink tubing is made of polyolefin, which is a very durable material. It's also strong and won't break or deteriorate over time, so your electrical connections should be safer for longer.
The inner surface of some heat shrink tubing contains a heat activated adhesive lining. When it is heated, the adhesive melts and forces air out, creating a strong, airtight seal. High-quality glue should also be waterproof and leave no gaps, even if it is wrapped around a cluster of wires.
The next thing you should consider is whether the product has the right safety features for your particular installation, and you should also check whether it is suitable for both indoor and outdoor use - or whether the product is intended for use only inside buildings. When you're working in high-risk areas, choose tubing with a variety of safety features, such as oil, water and corrosion resistance. Making safer electrical connections is important for both the installer and those who will use the connections after installation. Heat shrink tubing helps protect electrical systems, but if the tubing is not rated to withstand the environment in which it is installed, it can lead to many different problems in the future.
You should first determine the ideal tube size and shrinkage rate. Keep in mind that the tube must span its width and length, and it should also comfortably cover any cables or components before shrinking to provide a solid fit afterward.
If the size of the tube cover assembly changes after use, double-check the expandability of the tube by comparing its diameter after shrinkage to its diameter before shrinkage. You should also check the tube manufacturer's recommended heating temperature to help avoid uneven application or melting.
Use ordinary scissors to cut a sufficient length of tube and place or slide it onto the tip. Then simply heat shrink and wrap it. You can use a heat shrink oven, heat gun or even a heat blower to do this. Heat guns are specialized tools for more accurate and complex heating applications, so they may be the right tool for your job, depending on the complexity.
To help reduce the chance of burns when using a heat gun, move the heat back and forth through the tube rather than holding it in one place. You should then continue to wrap the wire until it covers the entire connection area.
Wirefy heat shrink tubing is a great choice whether you're looking to repair damaged wires or seal in moisture. This heat-activated tubing shrinks to one-third of its original diameter to help create a secure and tight connection, which helps prevent shorts and voltage drops.
