How to Choose The Best Car Heat-Shrink Tubing under $15 for You?


The most important aspect of choosing the correct heat shrink tubing products for your needs is understanding and defining what is needed for your applications. Once you define all that is needed for your application, and you choose an appropriate tube size, you are ready to select your heat shrink materials. The next step is determining the most appropriate tube size for your application. 

These two dimensions will be used later on in Step 2 to help determine the required dimensions and shrink factor of your tubing. Its expansion ratio helps you select the correct shrinkable tube for the parts and connections that need covering. 

The shrinkage is called longitudinal shrinkage in tubing specifications, but it is not always provided with all products of heat shrinkable tubing. Because these products can vary in size quite dramatically, the heat shrink ratio is also an important spec to look at to ensure that you are getting a proper fit with heat shrinkable tubing. Check that your heat shrinkable tubing has a shrink ratio that is high enough so you can achieve a tight fit over the smaller parts that you want to encapsulate. 

When heated, a shrinkable tubing length shrinks 5 to 7 percent, so be sure to select a tubing a little longer than the area of the applicability you wish to cover. To figure out the correct shrink tube size, just measure the diameters of the small and large parts you plan to cover with your tube, and then select heat-shrinkable tubing that is twenty to thirty percent larger than your larger measurements. 

Always select a diameter that is, once shrunk, slightly smaller than the diameter of your cable. Always choose a heat shrink with a diameter that is smaller, when fully recovered, than the diameter of the cable sleeving, connector, or tubing that you wish to cover. 

Going through these steps, and considering applications, single wall versus the double wall, materials, sizes, and colors, should help you narrow down which heat shrink is the right fit for your situation. Due to the difference in sizes amongst heat shrink tubes in the industry, knowing which one you can comfortably sit down to work with is essential. Whether you are using heat shrink tubing for electrical applications, for tension relief, for protective cover, or any other use, knowing the right size is the most important factor. Because the longitudinal shrinkage depends on different tubing characteristics, it is best to find out from your supplier what longitudinal shrinkage is expected for your heat shrink products. 

A good heat shrink product data sheet will list not only the tubing's minimal expander ID and nominal shrink rate, but its maximum recovery ID. Remembering this will be across both its width and its length If the part being covered may have changed in size post-application, make sure that the tubing has adequate expansion capability by comparing its diameter after shrinkage (called recovered diameter) to its pre-shrinkage dimensions (called expanded diameter). The determination is crucial to choosing the required tube sizes in Step 2. How to Choose the Right Heat Shrink Tube Dimensions Determining which size heat shrink tubing you need starts with the diameter of the material you are going to cover.
