60mm Dual-Wall Heat Shrink Tubing – 2:1 Shrink Ratio | Waterproof, Adhesive-Lined Cable.

The 60mm Dual-Wall Heat Shrink Tubing provides superior insulation, environmental sealing, and mechanical strain relief. With a 2:1 shrink ratio and a thermoplastic adhesive lining, it’s ideal for professional-grade applications in automotive, marine, industrial, and high-vibration environments.

Key Features:

• 2:1 Shrink Ratio:
  Reduces to 50% of its original diameter when heated, forming a tight, uniform wrap around oversized cables, joints, or splices.

• Dual-Wall Adhesive Lining:
  Features a rugged cross-linked polyolefin exterior and an inner thermoplastic adhesive that flows and bonds when heated—then cools to form a durable, watertight seal.

• Waterproof & Dustproof:
  Once shrunk, the adhesive fills surface gaps and protects against moisture, dirt, and corrosion—ideal for harsh or outdoor environments.

• High Pullout & Vibration Resistance:
  Designed to withstand cable movement and mechanical strain, significantly reducing the chance of cable disconnection or failure in high-stress conditions.

• Stress-Point Reinforcement:
  Perfect for terminating or reinforcing power, coaxial, or signal cables where sharp bends, flexing, or vibration are frequent.
