Heat Shrink Wrap Around Sleeve is a cross linked polyolefin 'tube' which is folded around the cable / pipe, zipped up with a stainless steel channel then heat shrunk.

Shut down of system not required for repair.
  • Hotmelt adhesive provides complete environmental sealing and insulation.
  • High resistance to UV rays, chemicals, corrosion, fungus, etc.
  • Temperature sensitive paint changes colour When heat shrinking process is complete.
  • Maximum length available upto 1500mm.
