## Description

PVC insulator for wrapping and protecting battery packs, ideal for 18650 4S configurations, folded width 170 mm, circumference 340 mm, length 1 m. Shrinks evenly at 100 degrees C, with a shrinkage rate of 48 percent horizontally and 12 percent vertically, offers high resistivity and a blue finish for quick identification.
Heat-shrinkable PVC tube, 170mm, insulating, used for wrapping battery packs.
The size refers to the width of the folded tube (its circumference being double). To correctly calculate the size of the tube, measure the perimeter of the battery and choose a tube with a size larger than its circumference.
