Wrap it around the threads of a cooling system temperature sensor, and it may block the flow of low-power electronic signals the computer needs to operate the machine. If you need a pipe thread lubricant, use a paste or gel product rather than tape. Stretch and stick Of the three universal tapes, the most task-specific is electrical tape. Unlike the other two, electrical tape does not have any kind of fabric core. This is because electrical tape is designed to stretch, and actually works better and sticks tighter if it is stretched while it is being applied.
Electrical tape is a two-layer product.
This is coated with a very thin layer of glue. The problem is that if the glue were extremely good, it would prevent unwinding the roll. Stretching the tape activates the glue, so it will stick to the underlying surface and to the back side of the tape as you wrap and overlap. The stretched tape will try to pull back to its original length, and this tension increases its grip. In most machinery applications, a single layer of tape provides more than enough insulation for 12-volt electrical current.
