Heat Shrink tube 40mm

Key Features

• 2:1 Shrink Ratio
  Shrinks to 50% of original diameter when heated, offering a reliable fit over cables, connectors, and bundled wires. Ensures secure coverage and mechanical stability.

• Dual-Wall Construction
  Combines a cross-linked polyolefin outer layer with a thermoplastic adhesive-lined inner wall. The inner resin melts during heat application, then solidifies upon cooling to create a moisture-tight, vibration-resistant seal.

• Sealing and Mechanical Protection
  Guarantees pullout resistance and slip prevention, ideal for long-term reliability in harsh environments. Prevents moisture ingress and enhances insulation integrity.

• Reinforcement at Stress Points
  Provides mechanical reinforcement where cables interface with connectors—particularly useful in applications with tight bend radii (e.g., coaxial cables), minimizing stress and potential damage.
