  • High shrink-ratio heavy-duty heat shrinkable tubing designed to pass over large size connectors and shrink down onto much smaller cable jackets.
  • The thermoplastic adhesive lined tubing provides environmental sealing, excellent insulation and resistance to impact and abrasion.
  • The 6:1 shrink-ratio conforms well to highly variable substrate dimensions and simplyfies cable repair.


Brand Family HA67
Color Black (BK)
Description HA47 is a thick-wall adhesive lined heat shrink tubing for use in applications up to 1000 volts. The adhesive lining provides excellent moisture sealing and weather protection, making it suitable for above and below ground applications. Made of a polyolefin outer material, this tubing has a shrink ratio up to 3.5 to 1. The adhesive lining begins to activate as the temperature approaches 185° F (85° C).
