How to choose the size

  • If you want to convert flat width to round width, multiply flat width by 2/pi.
  • If you have a battery pack to cover that is say 10cm x 15cm rectangular, you can paste the following into Google... pi*sqrt((10/2)^2+(15/2)^2)). This gives a flat width that you need of 28 cm (280mm). So, simply replace 10 and 15 in the formula with your width and height and paste into Google. This formula will calculate the rectangle to exactly fit within the round shape of the end of the tube (corners of rectangle touching the circular end of the heat shrink). This means that slightly smaller should be okay because you can manipulate the shape of the heat shrink (make it more like a rectangular shape to get it over the battery pack). You can use much larger heat shrink because of the large shrinkage ratio of PVC heat shrink. Slowly apply heat due to the low melting temperature of PVC.
