Quadrios 23CA173 Adhesive-Lined Heat Shrink Tubing, 3:1, Black, 6.4mm/2.1mm, 10m

Electrical connections exposed to moisture, dirt, and mechanical stress often fail prematurely. The Quadrios 23CA173 heat shrink tubing solves this by providing a durable, waterproof seal around cables and connectors. Its inner adhesive lining melts during shrinking, filling gaps and creating an environmental barrier that protects against corrosion and vibration.

Who is it for

Electricians, automotive technicians, marine installers, and DIY enthusiasts who need reliable insulation and sealing for wire splices, cable ends, and connector transitions. It is suitable for low-voltage and high-voltage applications up to 125°C.

Main features

• 3:1 shrink ratio: shrinks to one-third of its original diameter for a tight fit over irregular shapes
• Adhesive lining: melts and flows during heating to seal out moisture, dust, and chemicals
• Polyolefin material: flexible, flame-retardant (UL224 VW-1), and resistant to common solvents
• Wide operating temperature range: -55°C to +125°C
• High dielectric strength: 15 kV/mm for effective electrical insulation
• UV and chemical resistance: suitable for outdoor and harsh environments
• Continuous 10-meter length: cut to the exact size needed, reducing waste

Tips

Use a heat gun with a deflector nozzle for even shrinking. Start heating from the center and work outward to avoid air pockets. For best adhesion, clean the cable surface with isopropyl alcohol before applying the tubing. Allow the tubing to cool completely before flexing the connection.
