Product Name:
UV Resistant, Ozone Proof, 4x Expansion – Silicone Cold Shrink Tube
Product description:
Silicone cold shrink tube offers up to 4x expansion, fitting different diameters with strong resilience and long-term moisture proofing.
This silicone cold shrink tube provides excellent weather resistance, UV protection, and ozone aging resistance.
Even if cut, silicone cold shrink tube will not tear further due to its high tear strength.
Installation is simple – no heat or special tools required for silicone cold shrink tube.
The silicone cold shrink tube breathes with the cable, achieving active sealing while maintaining tight radial pressure.
Choose silicone cold shrink tube for reliable, long-lasting waterproof sealing of coaxial cables and connectors.
Applicable fields:
- Used for waterproof sealing of coaxial cables in telecom base stations.
- Suitable for N-type connectors, 1/2 jumpers, and DIN connectors.
- Works for cable TV connector waterproof sealing.
- Can be used for wire and cable connection sealing.
- Ideal for other types of electrical connection and insulation sealing.

FAQ:
Q1: What is the maximum expansion ratio?
A: Up to approximately 4x the original diameter, fitting different connector sizes.
Q2: Does it require heat or special tools for installation?
A: No. Installation is simple – just remove the core and let it shrink.
Q3: Is it resistant to sunlight and ozone?
A: Yes. It offers excellent UV protection and ozone aging resistance.
Q4: What happens if the tube gets cut during installation?
A: The cut will not expand further due to its high tear strength.
