Quadrios 25CA501 Adhesive-Lined Heat Shrink Tubing, Transparent, 3:1, 1.6 mm, 1 m

Heat shrink tubing with adhesive lining provides a waterproof and mechanically robust seal for electrical connections. The 3:1 shrink ratio allows the tubing to conform tightly over connectors and splices, while the inner adhesive melts during shrinking to create a durable, moisture-resistant barrier.

Advantages

Transparent polyolefin construction permits visual inspection of the sealed area after installation. The adhesive lining ensures a reliable seal even on irregular shapes, and the tubing is self-extinguishing (UL224 VW-1) for added safety.

Suitable for

• Insulating and sealing wire splices and terminations
• Protecting connections in automotive, marine, and outdoor applications
• Strain relief for cables and connectors
• Bundling wires where transparency is required

Recommendations

For best results, use a heat gun set to 125°C and apply heat evenly around the tubing until it fully recovers and the adhesive flows. Allow the assembly to cool before handling.
