  • Easy, time-saving insulation of cable branch point where it splits into single wires.
  • Adhesive to relieve mechanical tension in cable harnesses.


Application Cable breakouts are manufactured from a tough cross-linked polyolefin containing a flame retardant. This allows the breakouts to be used for both interior and exterior applications. They offer excellent electrical and mechanical protection.
Cable breakouts are supplied with an adhesive inner coating for reliable environmental sealing, and are available for 2, 3, 4, 5 and 6 core cables.
