PVC Heat Shrink Tubing 130mm Wide – Battery Wrap & Insulation Sleeve, 7 Colors

Measure the total length of the battery pack or wire bundle you need to cover, then add at least 10–15% extra to account for slight shrinkage along the length axis. For example, a 100mm (≈3.9") battery cell typically needs about 110–115mm of tubing. Available lengths range from 1 Meter (≈39.4") to 10 Meters (≈393.7") — choose a longer roll if you're wrapping multiple packs or want workshop stock on hand.

PVC heat shrink tubing generally has a 2:1 shrink ratio, meaning it shrinks to approximately half its original flat width when heat is applied. At 130mm flat width, the recovered diameter is typically around 65mm (≈2.6"). Always verify your battery pack's outer circumference — it should be less than 260mm (≈10.2") for this tubing to fit properly before shrinking.

PVC heat shrink tubing typically activates at 70–90°C (158–194°F). A standard heat gun set to low or medium is the recommended tool. Move the heat gun evenly along the tubing to avoid hot spots. Avoid open flames — they can scorch or melt the PVC unevenly and may damage the component underneath.

PVC heat shrink tubing provides basic moisture resistance and is generally suitable for indoor and light-duty outdoor use — for example, protecting battery packs stored in a garage or shed. For prolonged outdoor exposure, UV environments, or submersion, an adhesive-lined polyolefin tubing rated for outdoor use is generally a better choice.

At 130mm flat width, this tubing is typically compatible with large cylindrical battery packs and multi-cell series/parallel assemblies. It is commonly used on groups of 18650, 21700, and 26650 cells assembled into packs for e-bikes, power tools, and DIY power walls. Always measure the outer circumference of your assembled pack — it should be under approximately 260mm (≈10.2") for a proper fit before shrinking.

Yes. PVC heat shrink tubing is widely used for electrical insulation in DIY electronics, battery wrapping, and wire management. It provides a dielectric barrier that helps prevent short circuits on exposed terminals and solder joints. For high-voltage or safety-critical applications, contact us to confirm the voltage rating for the current production batch before ordering.

Yes — the tubing can be cut cleanly with standard scissors or a utility knife before applying heat. Cut it slightly longer than your target coverage area, slide it over the component or battery pack, then apply heat evenly to shrink it into place. The tubing will not shrink significantly along its length, so your cut length is generally your final covered length.
