The elastomeric tube which, when stored, is placed on a spiral plastic cord. This cord is removed during installation. Made of durable rubber, the tube has high dielectric characteristics (25 kV/mm) and is resistant to fungi, acids and alkalis. It has a high shrinkage coefficient, which allows it to be used in a wide range of cable size.

Technical features

  • Shrinkage of the tube is carried out without special tools, by removing the spiral plastic cord after installing the tube at the place cable splice.
  • Shrinking the tube does not require the use of a gas burner or a heat blower.
  • After shrinkage, due to the constant radial pressing of the tube on the cable jacket, reliable sealing of the splice is ensured.


  • Primary electrical insulation when splice wires and cables for voltages up to 600 V.
  • Protective jacket low-voltage and medium-voltage cables.


  • Voltage: up to 1 kV
  • Dimensions: Diameter before shrinkage/after shrinkage: 72/21 mm
  • Material: EPDM rubber
  • Color: black
  • Operating temperature range: -20°C to + 90°C
