Product Introduction:
1. The Silicone cold shrink tube requires no heat gun or torch — just pull the inner cord and it shrinks instantly.
2. With a 4:1 expansion ratio, one Silicone cold shrink tube fits multiple cable diameters, making field installation much easier.
3. This Silicone cold shrink tube offers strong rebound resilience, excellent long-term moisture protection, and complete waterproofing.
4. The material is UV resistant, ozone resistant, and weatherproof — the Silicone cold shrink tube won’t crack under sunlight or extreme temperatures.
5. Tear strength is outstanding: even if you cut a small slit, the Silicone cold shrink tube will not continue to tear.
6. Once installed, the Silicone cold shrink tube actively seals by breathing with the cable, maintaining constant radial pressure over time.
Expansion ratio: up to 4:1
