Here is a set of 7 black heat shrink tubing of 7 different diameters, and self-adhesive. The glue allows the sheath when heated to be still and not move at all.
A ratio of 3: 1 means that the diameter of the sheath once heated will be divided by 3: for example for a 9mm sheath, after being heated its diameter will be 3mm.
- Retractable Ratio: 3: 1
- Diameter (mm): 3.2 / 4.8 / 6.4 / 7.9 / 9.5 / 12.7 / 15.7
- Length: 50cm
- Color: Black
