Silicone Cold Shrink Tube – 4:1 Expansion, UV Proof, Teardown Resistant
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.

FAQ
Q1: What is a Silicone cold shrink tube?
A: A rubber tube that shrinks instantly when you pull out the inner support cord — no heat required.
Q2: Do I need a heat gun?
A: No. That’s why it’s called “cold shrink.” Just pull the cord.
Q3: How many times can it expand?
A: Up to 4x its original size. One tube fits different cable diameters.
Q4: Is it waterproof?
A: Yes. It provides full waterproofing and long-term moisture protection.
Q5: Can it handle outdoor conditions?
A: Yes. It’s UV resistant, ozone resistant, and weatherproof.
Q6: What if I cut it accidentally?
A: The tear will not spread — excellent tear strength.
