Heat Shrinkable Tubing 3:1 on a Reel 24/8 black
Art.-No. 308-32400 | HIS-3-24/8-PO-X-BK

Copied
  • HIS-3 with 3:1 shrink ratio, unlined tubing is the new generation of tubing in dispenser packs fitting highly variable substrate dimensions.
  • Another great benefit of HIS-3 is that only 5 sizes cover the same range of diameters from 1mm up to 20 mm in 10 sizes of 2:1 shrink ratio tubing, thus reducing the inventory by half.
  • As completion the inbetween sizes of 9/3 + 18/6 are also available.
Application HIS-3 is used in general purpose of electrical insulation with a high level of protection against mechanical abrasion.
