3:1 Polyolefin heat shrink will shrink down to one third of its nominal diameter, and less than 10% of its length.
The diameter of heat shrink tubing is measured as a round tube, not flat, so make sure that the shrink tubing is larger than what you are covering.
Use the 3 to 1 heat shrink tubing to insulate cables and wires, provide a protective barrier, strengthen cable joints and color code wires.
Attention: Due to the nature of the manufacturing process, same colors may not exactly match between sizes, models and batches. Sizes given are approximate and will vary.
All Heat Shrink is measured round, not flat
