EPDM cold shrink tube for cable joint and termination protection
Product name:
EPDM cold shrink tube for cable joint and termination protection
Description:
EPDM cold shrink tubes offer a safe, flame-free solution with consistent compression and long-lasting insulation — even in demanding conditions.
Once the core is pulled out, the tube contracts naturally and evenly around the cable, creating a secure seal without heat, flame, or special installation tools.
Features:
- Tool-free installation
- Uniform radial pressure for consistent sealing
- High dielectric strength for electrical insulation
- Excellent resistance to moisture, chemicals, and aging
Applications
- Power cable insulation and joint protection
- Telecom cable sealing
- Outdoor connectors and terminals
- Moisture and contamination protection

Introduction:
Cold Shrink Tubes are a series of open-ended, tubular rubber sleeves, which are factory expanded and assembled onto a removable core. They are supplied for field installation in this pre stretched condition. The core is removed after the tube has been positioned for installation over an in-line connection terminal link allowing the tube to shrink and form a waterproof seal. The insulating tube is made of EPDM rubber which contains no chlorides or sulphurs.
