The EPDM Silicone Cold Shrink Tube offers a reliable and fast solution for insulating and protecting cable connections. Its pre-expanded tubing shrinks around the cable when the rip cord is pulled, forming a tight, durable, and moisture-resistant seal without the need for heat, torches, or tools.

Designed for high-voltage applications, this cold shrink tube maintains its resiliency and sealing performance even after prolonged exposure to UV light, ozone, acids, alkalies, and extreme weather conditions. The advanced silicone/EPDM compound ensures excellent electrical insulation, waterproofing, and mechanical flexibility, making it ideal for outdoor telecom, utility, and industrial cable installations.

Available in multiple diameters and lengths, the  EPDM Silicone Cold Shrink TX-CST series accommodates a wide range of cable sizes, ensuring compatibility with most standard high-voltage cables. Its robust construction guarantees long-term performance, chemical resistance, and safe operation in harsh environments.

  2. RoHS Compliant – Environmentally safe materials.
  3. IEC 60811 & IEC 60216 – Meets cable insulation and durability standards.
  4. UV & Ozone Resistance Testing – Long-term outdoor reliability.
  5. High Voltage Rated – Rated for 1 kV applications.

Material & Construction:

  • EPDM and Silicone rubber for heat resistance, flexibility, and long-term durability
  • Waterproof, chemical-resistant, and fungus-resistant
  • Rated for high-voltage applications up to 1 kV
  • Black standard color, customizable options available

Installation Guide

  1. Slide the pre-expanded tube over the cable connection.
  2. Align properly to cover the splice or termination completely.
  3. Pull the rip cord to shrink the tube around the cable.
  4. Check for full compression and sealing along the connection.
  5. Trim excess if needed or remove during maintenance.
