Heat Shrink tube 50mm

The 50mm dual-wall heat shrink tubing is engineered for durable electrical insulation, moisture protection, and mechanical reinforcement. With a 2:1 shrink ratio and a heat-activated adhesive lining, it creates a secure, watertight seal over wires, connectors, and splices.

Key Features

• 2:1 Shrink Ratio
  Designed to shrink to 50% of its original diameter upon heat application, ensuring a snug and secure fit over large-diameter cables, connectors, and bundles.

• Dual-Wall Construction
  Engineered with a durable polyolefin outer layer and a thermoplastic adhesive-lined interior. The adhesive melts during heat application and re-solidifies on cooling, forming a permanent, watertight bond to both the tubing and underlying components.

• Environmental Sealing & Pullout Resistance
  Once fully shrunk, the tubing offers exceptional protection against water ingress, dust, and mechanical stress. The adhesive bond prevents movement or slippage, enhancing reliability in harsh or outdoor environments.

• Stress Relief for Large Cable Assemblies
  Ideal for coaxial or power cable terminations, especially in areas prone to frequent bending or mechanical load. Enhances structural integrity at transition points where cables are most vulnerable.
