Dunbar 3:1 Duall Wall Polyolefin Heat Shrink Tubing

Special features about 3:1 Dual Wall Heat Shrink Tubing

  • Internal meltable sealant
  • When heated above 120 oC, shrinks to 1/3 of its original size, and its internal sealant melts and provides a moisture-proof seal for encapsulation of wires, splices, breakouts and components
  • Its flame retardant nature helps protect wires and cables in high temperature applications.
  • Resists Common Automotive Chemicals and Easily Installs Over Connectors and Splices
  • Black colored is UV-resistant for extended outdoor use
  • Meets M23053/4 specifications
  • Excellent Electrical Properties
  • Great protection in high humidity and corrosive environments
When heated above 120C the tubing will shrink to approximately 33% of its original diameter. As it shrinks, the internal sealant melts and provides a moisture-proof seal for encapsulation of wires, splices, breakouts and components.
