4:1 Polyolefin Dual-Wall Heat Shrink Tubing — Adhesive-Lined Waterproof Cable Insulation Wrap

Dual-wall polyolefin heat shrink with a 4:1 shrink ratio and an inner adhesive liner. When heated the adhesive melts to form a watertight, moisture-sealing barrier around cables and splices. Designed to provide abrasion resistance and protect against corrosion while delivering environmental protection for wire insulation. Ideal for waterproofing, insulating, and repairing electrical connections and wiring assemblies.
