HOW TO SELECT THE CORRECT SIZE TUBING FOR YOUR APPLICATION TE Connectivity Heat Shrink Tubing White Paper APPLIANCES /// HOW TO SELECT THE CORRECT SIZE TUBINGHow to Select the Correct Size Tubing White Paper INTRODUCTION: HOW TO SELECT THE CORRECT SIZE TUBING FOR YOUR APPLICATION BRST TUBING DWFR TUBING Heat Shrink Tubing, unlike many other products is designed to change shape when installed. Correctly sized tubing will conform to the substrate over which it is applied. It shrinks in diameter and in general overall length. This can make it especially tricky to select the right size for your application. This guide was put created to help with that process. ATUM TUBING SCT 1 TUBING 0.50+ 0.05 (i.e.-10% Recovered ID vs. Length Shrinkage of 0.5) = 0.55 to Size of Substrate Just as the tubing will shrink in diameter, 1 - .2 (i.e. - 20% of 1.0) = 0.80 it will also shrink slightly in overall To achieve a good robust installation length during the recovery process of heat shrink tubing it is important Or in other words, it is intended to cover (in general in some case it can grow to get the best fit of the tubing to something that measures between in length). Different products have the substrate. To do this, the tube 0.55- 0.80 outside diameters. different longitudinal shrinkage %s. needs to shrink by at least 20% of its Will the heat shrink tubing work in supplied size but not so far that the Please consult with a Field Applications the zone outside the recommended tube reaches its fully recovered size.
