Quadrios 25CA492 Adhesive-Lined Heat Shrink Tubing, 3:1, White, 25.4 mm Diameter, 1.2 m Length

Exposed wiring and cable splices are vulnerable to moisture, corrosion, and mechanical stress. This adhesive-lined heat shrink tubing seals and protects connections, providing a durable, waterproof barrier that keeps electrical systems reliable in harsh environments.

Who is it for

Electricians, automotive technicians, and DIY enthusiasts who need to insulate and seal cable joints, splices, or terminations. Ideal for outdoor, marine, and industrial applications where long-term protection is critical.

Main features

• Dual-wall design: cross-linked polyolefin outer jacket with inner thermoplastic adhesive lining
• 3:1 shrink ratio conforms tightly to irregular shapes and connectors
• Adhesive melts during shrinking to create a waterproof, strain-relieved seal
• White colour for easy identification and professional appearance
• Flame retardant and self-extinguishing for added safety
• UV and weather resistant for outdoor use
• Wide operating temperature range from -55°C to +125°C
• RoHS compliant

Tips

Use a heat gun with a deflector nozzle for even heating. Start shrinking from the centre and work outward to avoid air pockets. Ensure the tubing is centred over the splice and allow it to cool completely before handling.
