2 Inch Heat Shrink Tubing - 5 Ft 3:1 Ratio Waterproof Adhesive Lined Dual Wall Shrinkable Wire Wrap Tube

Heat Activated Adhesive Lining This is a waterproof shrink tubing with an 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 gaps between the wire and the tubing, making the connection waterproof. For best results, we recommend using a heat gun. Dual Wall Shrink Tubing Dual wall marine grade heat shrink tubing provides better rigidity and abrasion resistance. Dual wall tubing design has the increased ability to withstand wear and tear. This wire heat shrink tubing is flame retardant.
