For EPDM cold shrink tube, the shrink ratio is 3.5:1.




2. What’s the lifespan of Volsun cold shrink tube ?
Volsun cold shrink tube will match the lifespan of the cable that it's protecting.
 
3. How do you remove the cold shrink tube after installed?
Due to the high shrinkage ratio, the cold tube will be tightly wrapped in the cable (or something else) after installed, therefore, cold shrink tube should be removed with a blade or scissors.
