Description

Silicone cold shrink tube is a high-elastic, tool-free sealing solution designed to provide long-lasting mechanical and environmental protection for cable joints and connectors. After the inner core is removed, the silicone material automatically contracts, creating a uniform, compressive seal that adapts to various cable shapes—including irregular and uneven surfaces.
Built for extreme environments, it resists UV exposure, salt spray, degradation, vibration, and rapid temperature changes, making it ideal for field installations where durability and efficiency matter.

Features 

• Automatic Cold Shrink Design – No heat, no adhesive, no tools required. Simply pull the core and the tube shrinks instantly, ensuring consistent installation across all field conditions.

• High-Elastic Silicone Body – Superior flexibility allows the tube to conform tightly around uneven, textured, or irregular cable surfaces, providing a stable and continuous seal.

• Exceptional Waterproof Performance – Forms a seamless, moisture-blocking barrier ideal for outdoor exposure, preventing rain, condensation, and humidity from reaching sensitive components.

• Enhanced UV & Weather Resistance – Silicone rubber resists cracking, hardening, and degradation under long-term sun exposure, heavy rain, and extreme climates.

• Faster Installation & Lower Labor Costs – Perfect for field repairs, emergency work, and large-scale deployments where speed and consistency are critical.

• Anti-Vibration, Anti-Slip Seal – Maintains tight compression under mechanical stress, ensuring long-term stability even in high-vibration installations.

Application 

• Outdoor Power Cable Joints – Provides long-term sealing and protection for utility power lines, underground connections, distribution boxes, and outdoor electrical interfaces.

• Telecom & Antenna Systems – Ideal for RF connectors, coaxial lines, antenna feeders, and base-station equipment exposed to wind, rain, and temperature shifts.

• 5G Tower & Infrastructure Installations – Ensures reliability in high-altitude equipment facing constant environmental stress.

• Automotive & EV Wiring Harnesses – Protects connectors, sensors, charging system cables, and exposed harness points in vehicles and electric mobility systems.

• Marine, Offshore & Coastal Environments – Withstands salt spray, high humidity, marine vibrations, and corrosion-prone conditions.

• Solar Power & Renewable Energy Systems – Strengthens protection for PV connectors and outdoor DC cable joints under intense sunlight.

• Industrial Machinery, HVAC & Control Cabinets – Seals electrical interfaces inside factory equipment, automation lines, and outdoor control boxes.

• Emergency Repairs & Field Maintenance – Ideal for rapid waterproofing or protective reinforcement during outages, remote-site jobs, or time-sensitive repairs.
