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.
