• UV resistant for outdoor use
• Black colour for a neat, professional appearance

In daily use

This tubing is suitable for insulating splices, protecting cables from abrasion, and providing strain relief. The 3:1 shrink ratio means it can slide over larger connectors and still shrink down tightly onto smaller cables, making it a flexible choice for maintenance and repair work. The polyolefin material is flexible and resistant to common chemicals, ensuring long-term durability in demanding environments.
