EPDM Cold Shrink Tubing
Insutek EPDM cold shrink tubing is a rubber insulating sleeve which is pre-expanded on a removable plastic cord. When applied, the tubing will be bounced back automatically and seal tightly onto the connectors. It has excellent weather resistance, acid and alkali resistance. It is an ideal sealing product for antennas, coaxial cables, DIN connectors etc.

Features/Benefits
- Made from EPDM rubber, which contains no chlorides or sulphurs.
- Compared with heat-shrinkable tubes, it is more weather-resistant and UV-resistant, and anti-aging.
- Compared with silicone rubber cold shrinkable tube, it is more resistant to puncturing, abrasion resistance and acid and alkali resistance.
- Synchronous expansion and contraction with the connector in a harsh environment, no gaps, tight seal.
- Suitable for power cables below 1KV, widely be used indoors, outdoors, overhead, water or buried occasions.
- Strong resilience, long-term radial pressure, long-term tight cable seal
- Easy to be installed, no need for heating or special tools, no need to hot melt adhesive or tape to strengthen the joint
