Questions about this product
- How much does this tubing shrink, and how do I choose the right size?
- This tubing has a 2:1 shrink ratio, meaning it shrinks to half its original diameter when heated. Make sure your wire is slightly larger than the fully recovered diameter of the size you choose. The tubing also shrinks in length by about 5%.
- What temperature do I need to use to make this tubing shrink properly?
- The tubing starts shrinking at 70°C, but it needs 110°C to shrink completely. You can use a heat gun to apply even heat until it fits tightly around your wire. Avoid overheating it past its limits.
- Can I use this heat shrink tubing in outdoor or high-temperature environments?
- Yes, this polyolefin tubing operates safely in temperatures from -55°C up to 125°C. It offers good UV resistance for outdoor projects and resists common fluids and solvents. It also has a VW-1 flame-retardant rating.
