Quadrios 25CA732 Teplom zmršťovacia bužírka s lepiacou vrstvou 32mm/8mm 4:1 čierna 5m

Quadrios 25CA732 stands out with its 4:1 shrink ratio and integrated adhesive lining, delivering a moisture-tight seal that standard heat shrink tubing cannot match. The 32 mm initial diameter recovers to 8 mm, gripping irregular shapes and sealing out water, dust, and solvents. This 5 m roll in black is made from cross-linked polyolefin, designed for permanent insulation and strain relief in demanding environments.

Highlights

• 4:1 shrink ratio for secure coverage over connectors and splices
• Adhesive lining melts during shrinking to create a waterproof barrier
• Wide operating range from -55°C to +125°C
• Excellent resistance to UV, chemicals, and abrasion
• 600 V dielectric strength for safe electrical insulation

In daily use

Slide the tubing over the connection, apply heat above 70°C, and watch it shrink uniformly while the inner adhesive flows into every gap. The result is a rugged, IP68-rated seal that stays flexible even in extreme cold. Use it for automotive wiring, marine repairs, outdoor splices, or any application where moisture and vibration are a concern.
