The 72mm PVC heat shrink tubing for batteries is an essential accessory for protecting and insulating battery packs and electronic components. With a length of 1 metre, 72 mm diameter and 0.08 mm thickness, this tubing offers a reliable and neat solution for securing your electronic projects.
Key features
- Dimensions: 1 metre long, 72 mm diameter and 0.08 mm thickness.
- Temperature range: Withstands from -40 °C to 105 °C, suitable for various environmental conditions.
- Shrink temperature: Starts shrinking at 80 °C, making it easy to use with hot air guns or lighters.
- Rated voltage: 300V, ensuring safe insulation for most electronic components.
- Colour: Vibrant blue that makes visual identification easier and improves appearance.
- Shrink ratio: Approx. 48±5%, ensuring a firm and secure fit over components.
Typical applications
This heat shrink tubing is ideal for:
- Battery packs: Insulation and protection for lithium batteries and other types.
- Electronic components: Protection for electrolytic capacitors, LEDs and other electronic devices.
- DIY projects and maintenance: Perfect for DIY, repair and assembly in workshops or at home.
- Neat finishes: Enhances and protects packaging, bottle combinations and other creative items.
How to use
- For smaller tubes, use a lighter for quick and controlled shrinking.
- For larger tubes, use a hot air gun for even heat distribution and effective shrinking.
- Avoid tools that could damage the tube, such as electrochromic irons.

Customer Questions & Answers
What are the main benefits of using this PVC heat-shrink tubing compared with traditional insulating tape for battery packs?
PVC heat-shrink tubing provides uniform coverage and a compact seal, resulting in better mechanical strength, greater protection against liquids and external agents, and more reliable electrical insulation than insulating tape. In addition, its quick heat-based application reduces the chance of errors and improves the final appearance of the product.
What exactly is included in the package, and what is the total weight of the tubing supplied?
This product includes a single PVC heat-shrink tube, 1 metre long, 72 mm diameter before shrinking and 0.08 mm thick. The approximate weight of the tube is 35 to 40 g, although it may vary slightly depending on the manufacturer.
Is this tubing compatible with 18650 cylindrical batteries assembled in parallel, or only with packs assembled in a row?
The tubing, with an original diameter of 72 mm and a guaranteed minimum shrink of 48±5%, can be adapted to both 18650 battery packs in a row and assemblies built in parallel, provided the total contour (including any solder joints) does not exceed the transformed diameter after shrinking (~37.4 mm if it shrinks by 48%). It is recommended to measure before applying.
What are the recommendations for correct installation and to avoid bubbles or wrinkles during shrinking?
For the best installation, clean and dry the surface before placing the tubing. Use a hot air gun and apply heat evenly from the centre towards the ends, rotating the part to avoid localised heat build-up. Avoid direct flames to prevent scorching the PVC.
What temperature or voltage limitations should be considered to avoid failures, especially in prolonged or demanding use?
The tubing is designed to operate between -40 °C and 105 °C and withstand up to 300 V. Continuous exposure to heat sources above 105 °C and to higher voltages should be avoided, as this can cause insulation degradation or protection failure. It is not suitable for industrial high-voltage applications.
What is 72mm PVC heat shrink tubing used for?
It is used to insulate and protect batteries and electronic components, providing electrical insulation and physical protection.
What temperature can this heat shrink tubing withstand?
It withstands temperatures from -40 °C to 105 °C, suitable for various environmental conditions.
How is the heat shrink tubing applied?
It is applied by heating with a hot air gun or a lighter so the tube shrinks and fits tightly over the component.
Is it compatible with lithium batteries?
Yes, it is ideal for assembling and insulating lithium battery packs and other types.
What colour is the tubing and why does it matter?
The tubing is vibrant blue, which makes visual identification easier and improves the appearance of the project.
