* The minimum expansion internal Ø (external Ø) is not tolerated. The dimensions can be much greater than the minimum values. Heat shrink tubing with tolerated ID (OD) is custom-made. We shall be glad to provide you information on this option that comes along with a special manufacturing process.

Often, the users select Heat shrink tubing having the shrinkage rate 4:1, since several dimensions can be covered with one size. However, please note that POLYTETRAFLON® Heat shrink tubing with rate 2:1 can be processed in a more application-friendly manner as compared to our heat-shrinkable tubing having a shrinkage rate of 4:1. We shall be glad to offer you technical consultation and we will find out the optimum Heat shrink tubing suitable for your application. Please contact us.
