PVC Heat Shrink Tubing for 18650 Cells

This 1 metre length of black PVC heat shrink tubing is designed to protect and repair the outer wrap of 18650 lithium-ion cells. It shrinks at 80 °C with a 48 % cross-section shrink rate and only 5 % longitudinal shrinkage. The tubing carries a 300 V voltage rating and operates from -40 °C to +105 °C.

Check Cell Diameter and Shrink Temperature

Before ordering, verify that the bare cell diameter is smaller than the 73 mm recovered diameter so the tube can fully enclose the 18650. Ensure you have a hot-air tool capable of reaching the 80 °C shrink temperature. Confirm that the 300 V rating and -40 °C to +105 °C operating range suit your application environment.

Single Length of Flame-Retardant Tubing

The package supplies one 1 metre piece of tubing with a 115 mm flat width. No additional tools, adhesives or identification markers are included. The material provides flame-retardant insulation and environmental protection on its own. Buyers needing pre-cut lengths, dual-layer construction or printed labelling will not find those features here.
