【Description】
The cold shrink breakout is a rubber insulated finger sleeve which is pre-expanded on the pumpable support tube. When it is used, it only needs to be positioned and then the support tube can be removed, and the radial pressure is used to form the cover, which is waterproof and moisture proof. effect. It has excellent weather resistance, acid and alkali resistance and the same breath sealing effect. It is an ideal sealing product for communication cables, coaxial cables and medium and low voltage power cables.
【Features】
- Suitable for connection seals of different diameters
- Strong resilience, long-lasting radial pressure, long-term moisture resistance, excellent water resistance
- Weather resistance, exposure to sunlight, ozone aging resistance, UV resistance, salt spray corrosion resistance
- Excellent tear strength. After cutting a small opening with a knife, the cutting will not continue to expand.
- Easy to install, no need for heating or special tools, no need for hot melt adhesive or tape to strengthen the joint
- Standard color: Gray
