4x Expansion Self-Amalgamating Waterproof Sealing Tape – UV & Ozone Resistant

Product Specification

Product Description

This high-performance silicone cold shrink tube is specifically designed for telecom base stations, coaxial cable connections, and RF connectors. With an expansion ratio of up to 4 times, this silicone cold shrink tube fits tightly around different diameters of connectors including N-type, DIN head, and 1/2" jumpers. Unlike ordinary tapes, this silicone cold shrink tube "breathes" with the cable to provide active sealing, preventing moisture ingress while allowing pressure equalization. The silicone cold shrink tube offers outstanding weather resistance, ensuring reliable performance under long-term sun exposure, ozone, and UV radiation. Easy to install without tools, this silicone cold shrink tube delivers strong resilience, high radial pressure, and excellent mechanical damage protection – making it the go-to solution for outdoor cable and connector waterproofing.

FAQ

Q1: Can this silicone cold shrink tube be removed easily after installation?
A: This silicone cold shrink tube is designed for long-term sealing. For removal, it is best to cut it off. It may leave some residue, but can be cleaned with isopropyl alcohol.

Q2: Does this silicone cold shrink tube work on wet cables?
A: For best results, the surface should be clean and dry. However, this silicone cold shrink tube can still seal effectively on slightly damp surfaces due to its self-amalgamating properties.

Q3: How much silicone cold shrink tube do I need per connector?
A: Approximately 10–15 cm of silicone cold shrink tube per N-type connector. One roll of silicone cold shrink tube covers 20–30 connectors depending on application.

Q4: Is this silicone cold shrink tube suitable for underwater use?
A: Yes, this silicone cold shrink tube provides 100% waterproof sealing and can be used for direct burial or underwater applications as long as properly installed.

Q5: What is the difference between this silicone cold shrink tube and PVC electrical tape?
A: PVC tape is not waterproof long-term and degrades under UV. This silicone cold shrink tube is self-amalgamating, weatherproof, and designed specifically for outdoor connector sealing.

Q6: Can I use this silicone cold shrink tube on live cables?
A: This silicone cold shrink tube has high dielectric strength (≥20 kV/mm), but proper safety procedures should always be followed. The silicone cold shrink tube is typically used on disconnected or de-energized cables.
