Additional Information

Heat shrink wire sleeves are made of different types of materials that shrink down to a fraction of the original diameter with the application of a heat source. 3:1 heat shrink tubing shrinks to 1/3 its original size.  3:1 Dual wall heat shrink tubing is available with our without adhesive lining.  Typically, adhesive line 3:1 tubing is used in applications where protection from moisture is absolute.  All of our 3:1 shrink ratio tubing is made with quality materials that are UL 224 VW-1 recognized.
