Quadrios 25CA734 zmršťovacia bužírka s lepidlom 52mm/13mm 4:1 čierna 5m

This adhesive-lined heat shrink tubing offers a 4:1 shrink ratio, allowing it to fit over connectors with large diameter differences while providing a tight, protective seal after recovery. The internal adhesive layer melts during shrinking to create a waterproof and corrosion-resistant barrier, making it suitable for demanding electrical insulation and environmental sealing tasks.

Highlights

• 4:1 shrink ratio for covering components with varying diameters
• Adhesive lining for waterproof and moisture-proof sealing
• Cross-linked polyolefin material with good chemical and UV resistance
• Operates from -55°C to +125°C, with minimum shrink temperature of 110°C
• Dielectric strength >15 kV/mm for reliable electrical insulation

In daily use

With an expanded inner diameter of 52 mm and a recovered diameter of 13 mm, this tubing is ideal for insulating large cables, splices, and connectors. The 5-meter length provides ample material for multiple applications, and the black colour offers a professional finish.
