Quadrios 25CA494 Adhesive-Lined Heat Shrink Tubing, 2:1, 6.4 mm, White, 1 m

This heat shrink tubing stands out with its integrated adhesive lining, which melts during shrinking to create a moisture-resistant seal. Unlike standard tubing that only provides insulation, the adhesive bonds to the underlying surface, preventing water ingress and adding strain relief for cable splices and connectors.

Highlights

• Adhesive-lined inner wall seals against moisture and contaminants
• 2:1 shrink ratio recovers tightly over irregular shapes
• White colour blends with light-coloured cables and enclosures
• Cross-linked polyolefin offers good electrical insulation and flexibility
• 1 m length allows cutting to custom sizes

In daily use

Slide the tubing over a splice or connector, apply heat from a hot air gun, and the tubing shrinks while the adhesive flows to fill voids. The result is a durable, water-resistant covering that protects against abrasion and environmental exposure. The white finish is easy to label and keeps installations looking tidy.
