Working with FEP shrink tubing is similar to using PTFE shrink tubing. The only difference is the amount of heat required to actually shrink the tubing around the cable or wiring. FEP has a lower shrinkage temperate than PTFE. This makes it suitable for use in applications where higher shrinkage temperatures may damage surrounding parts and components.
You Often Have to Cut FEP Shrink Tubing to Size before Using It
When you want to use FEP shrink tubing you will need to cut it down to size. This type of tubing often comes in four foot sections and most applications do not require a size this big. You should measure the area where you intend on using the tubing to obtain the size you require. You need to include extra length on both sides of the location in order to have a bit of an overlap. For example, if you are fixing an exposed wire, you want to make sure the shrink tubing is long enough to cover the exposed section and fully re-seal it.
