Copied
  • 90° (right angled) branching parts (T-joints) are used for a simple time-saving insulation of the branch point of a cable where it is split into single wires.
  • Adhesive lined T-joints also serve to relieve the mechanical tension in cable harnesses.


Application Heat Shrinkable molded shapes for use in Electrical and Electronic Cable Harness Applications.
Color Black (BK)
Description Helashrink 1200 Series provides sealing, strain relief and mechanical protection at cable branch points in electrical and electronic cable harness applications for 2-core cable applications. Adhesive-lined T-joints also relieve mechanical tension in cable harnesses.
