35mm Dual-Wall Heat Shrink Tubing – 2:1 Shrink Ratio, Waterproof & Adhesive-Lined

35mm Dual-Wall Heat Shrink Tubing – 2:1 Shrink Ratio, Waterproof & Adhesive-Lined

Product Overview:
Engineered for heavy-duty protection, this 35mm heat shrink tubing delivers both environmental sealing and mechanical reinforcement. Its dual-wall construction—featuring a cross-linked polyolefin outer layer and a heat-activated adhesive lining—ensures a reliable, watertight seal over cables, connectors, and splices in demanding environments.

Key Features:

• 2:1 Shrink Ratio
  Reduces to half its original diameter with heat, conforming tightly to irregular shapes and surfaces.

• Dual-Wall Design
  Combines a tough outer jacket with an inner thermoplastic adhesive that melts, flows, and solidifies for a permanent seal.

• Waterproof & Pullout Resistant
  Seals against water, dust, and debris while offering excellent strain relief and resistance to cable slippage.

• Stress Relief at Bend Points
  Ideal for connectors and joints prone to flexing—extends cable life and enhances joint durability.
