Frequently Asked Questions

What is cold shrink tube?

Cold shrink tube is a pre-stretched elastomeric tube that contracts to form a tight seal over cables and connections when released. Unlike heat shrink, it requires no heating tools, making it ideal for field applications.

What materials do you use?

We primarily use EPDM (Ethylene Propylene Diene Monomer) and silicone rubber. EPDM offers excellent weather and ozone resistance, while silicone provides superior flexibility and high-temperature performance.

Are your products ROHS compliant?

Yes, our cold shrink tubes and accessories meet ROHS standards, ensuring they are free from hazardous substances and safe for use in Europe and other regulated markets.

Can I get custom sizes or colors?

Yes, we offer customization for diameter, length, color, and packaging. Contact us with your specifications for a tailored solution.
