Clear Dual Wall Heat Shrink Tubing 3:1 Ratio with Heat Activated Adhesive - 4Ft (1”/25.4mm) Marine Grade Cable Sleeve for Wire Protection - Waterproof, Durable for Electrical, Automotive & Marine Applications

This is a waterproof shrink tubing with the internal adhesive layer. When heat is applied, shrink tubing recovers and the internal adhesive layer melts. A small fillet of clear adhesive (about 1 mm wide) becomes visible at the end of the heated tubing. When cooled down, it forms a rigid seal. Heat activated glue strongly adheres to wires, terminals or any other surfaces. When adhesive flows, it pushes the air out and fills any gaps between the wire and the tubing, which makes the connection waterproof. For best results we recommend using a heat gun. 3:1 SHRINK RATIO Apply hot sol evenly Wateproof Product Description The inner layer of the double-walled pipe is hot melt adhesive, which has good bonding performance, and the outer layer is soft, flame-retardant, irradiated cross-linked polyolefin, and its shrinkage rate is 3 times. , No maintenance, can withstand harsh environments, moisture and other impacts, to protect components. Scope of application Double-walled pipes are widely used in the wiring of electronic equipment, waterproof, leak-proof, multi-strand wire harness sealing and waterproofing (such as home wire harness, automobile wire harness, etc.), sealing moisture-proof, waterproof, corrosion-proof and insulation protection of components, wire and cable branches Sealing and waterproofing, corrosion protection of metal pipelines, repair of wires and cables, waterproofing of wiring of water pumps and submersible pumps, etc. Use tips Heat it with a lighter or a heat gun to shrink it. Notice: Please check carefully which size you need, we show Round Inner Diameter size and Flat Width size Before Shrinking.
