Quadrios 26CA771 Termorretrátil 2:1 sem cola preto 8 mm/4 mm 10 m

Quadrios 26CA771 offers a clean, adhesive-free solution for insulating and protecting cables and connections. Unlike adhesive-lined tubing, it leaves no sticky residue, making it ideal for applications where a dry, flexible cover is preferred. The 2:1 shrink ratio ensures a snug fit over irregular shapes, while the black polyolefin material blends seamlessly into most cable assemblies.

Highlights

• Adhesive-free polyolefin construction for residue-free insulation
• 2:1 shrink ratio for secure, uniform coverage
• Supplied as a 10 m continuous length for custom cutting
• Wide operating temperature range from -55 °C to 125 °C
• Flame-retardant to VW-1 standard

In daily use

This heat shrink tubing shrinks to half its original diameter when heated to 110 °C, creating a tight, professional finish. The unshrunk inner diameter of 8 mm easily slides over connectors, and after shrinking it reduces to 4 mm for a firm grip. The thin wall (0.25 mm before shrinking) remains flexible even at low temperatures, making it suitable for automotive, industrial, and DIY wiring projects.
