Many customers received heat shrink tubing , it is flat , so when they order heat shrink tube , they will just tell us the flat width of heat shrink tubing , but ordinary manufacturers will just ask which inner diameter do you need ! Of cause , we will convert into inner diameter when we get the flat width for customers .

You can also convert the flat width into inner diameter yourself , it is very easy : ineer diameter x 3.14 / 2 = inner flat width .

For example :

The heat shrink tubing in the picture below , flat width is 18mm , so out diameter will be 18×2/3.14=11.5mm , minus the thickness of the wall , inner diameter will be about 11mm , it is the heat shrink tubing you need .
