Everything you need to know about cold shrink tubing.
Cold shrink tubing is a pre-stretched elastomeric tube mounted on a removable core. When installed, the core is removed, allowing the tube to contract and form a tight, seamless seal over cables and connections—without requiring heat.
Unlike heat shrink, cold shrink requires no heat source, making it safer and easier to use in confined or hazardous environments. It offers superior sealing and is ideal for field repairs and high-reliability applications.
No, cold shrink tubing is designed for one-time installation. Once the core is removed and the tube contracts, it cannot be re-expanded or reused.
It is widely used in power distribution, telecommunications, automotive, aerospace, rail transit, and industrial electronics for insulation, sealing, and mechanical protection.
