Product name:
EPDM cold shrink tube for cable sealing and insulation
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, ideal for on-site and field work
- Uniform radial pressure for consistent sealing
- High dielectric strength for electrical insulation
- Excellent resistance to moisture, chemicals, and aging
Applications
- Power cable joints and terminations
- Telecom and data cable protection
- Outdoor and underground cable sealing
- Solar energy and renewable power systems

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.
