25mm Dual-Wall Heat Shrink Tubing – 2:1 Ratio, Waterproof & Adhesive-Lined

25mm Dual-Wall Heat Shrink Tubing – 2:1 Ratio, Waterproof & Adhesive-Lined

Product Overview:
This 25mm 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
  Shrinks to 50% of its original diameter when heated, forming a snug, protective fit.

• Thermoplastic Adhesive Inner Lining
  The adhesive melts during shrinking and bonds tightly upon cooling, offering superior sealing and strain relief.

• Waterproof & Pullout Resistant
  Ideal for outdoor or harsh environments—resists moisture ingress and cable slippage.

• Bend Point Reinforcement
  Adds mechanical strength at high-stress zones such as cable junctions and connectors.

Specifications:

• Nominal Diameter (Pre-Shrink): 25mm

• Shrink Ratio: 2:1

• Material: Polyolefin outer shell with inner thermoplastic adhesive

• Operating Temperature: -55°C to +125°C

• Shrink Activation: Begins at ~70°C, full shrink at ~110°C

• Environmental Protection: Waterproof with proper installation

Applications:
Perfect for cable terminations, repairs, automotive wiring, coaxial shielding, and field-ready electrical sealing.
