60mm PVC Heat Shrink Tubing for 18650 Battery Packs – 8 Colors

This tubing has a flat width of 60mm and an expanded diameter of approximately 38mm (≈1.5"). It is designed to fit single 18650 cells and small parallel packs. For larger multi-cell packs, measure your pack's outer diameter before ordering and confirm it falls below 38mm. A standard 18650 cell is typically 18mm (≈0.71") in diameter, so this tubing fits comfortably over one or two cells side by side.

PVC heat shrink tubing of this type typically has a 2:1 shrink ratio. Starting from an expanded diameter of approximately 38mm (≈1.5"), the tubing will generally shrink down to around 19mm (≈0.75") when heat is applied evenly. Actual recovered diameter may vary slightly depending on your heat source, distance, and application speed. Always do a short test piece before sleeving your full pack.

PVC heat shrink tubing of this type generally begins to shrink at around 70–90°C (158–194°F). A standard heat gun on a low or medium setting works well. Move the heat gun steadily along the tubing to avoid hot spots. Avoid using open flames — they can scorch or melt the PVC unevenly and may damage the cell wrapper underneath.

Yes. PVC heat shrink tubing is widely used for 18650 lithium-ion battery rewrapping and pack sleeving in DIY applications. It provides electrical insulation and mechanical protection for the cell casing. Keep finished packs away from sustained heat sources above the shrink temperature, as prolonged exposure could cause the sleeve to deform. For high-drain or high-temperature applications, verify the tubing's voltage and temperature ratings with us before use.

PVC heat shrink tubing generally offers basic moisture resistance once fully shrunk, making it suitable for light indoor use and sheltered outdoor applications. It is not a waterproof seal — moisture can still enter from the open ends. For fully waterproof battery pack sleeving or prolonged outdoor exposure, an adhesive-lined polyolefin heat shrink tubing is typically a more appropriate choice.

Measure the total length of the section you need to cover, then add at least 10–15% extra for overlap and trimming. A standard 18650 cell is approximately 65mm (≈2.6") long. For a 2S series pack (two cells end-to-end), you would need roughly 140mm (≈5.5") of tubing per sleeve. The 1M roll suits single-cell rewraps and small repairs; the 5M and 10M rolls are better suited for workshop use or building multiple packs.

No. All eight color options — White, Red, Green, Blue, Clear, Yellow, Silver Gray, and Black — are made from the same PVC material and share the same insulation and shrink characteristics. Color selection is purely for visual identification, organization by cell batch or capacity, or aesthetic preference in your battery pack build.

Yes. The tubing cuts cleanly with a pair of scissors or a sharp utility knife. Because it has no adhesive lining, it can be repositioned freely before heat is applied. Cut your piece slightly longer than needed, slide it into position, then apply heat from the center outward to avoid trapping air bubbles under the sleeve.
