4:1 Adhesive Lined Heat Shrink Tubing Roll Protection Wiring Sheath Harnesses Waterproof Glue Insulated Dual Wall (1"-22ft)

4:1 Ratio Quick and Solid: High-shrink ratio (4:1) making it easier to cover various difference size wires ,recovers to 1/4 of its original diameter,shrink was quick and solid,a real upgrade over the 3:1.
Adhesive Lining Waterproof Strong, Tight Seal: When heat is applied,it to shrink and melts a layer of glue/sealant that permanently bonds the tubing to the wire and seals,provides a good water-tight seal with the adhesive lining the inside of the tubing,sealed well around the cord.
Thicker Walls, Protection from Wear and Tear: When contracted, it can form a rather thick wall layer，but still flexible and not rigid like some of the heat shrink tube，better wear resistance it should hold up under strain or abrasion well，Provides enhanced protection.
Easy to Use: Simply slide the heat shrink tubing over the connection point and heat it up. easy to use can be shrink by heating with hot air gun in seconds for a professional insulated connection.
Size and Note: 1/2" (12.0 mm) shrink tubing diameter (round state):Get the exact diameter you need .(The shrink tube data shown in picture are the inner diameter of the heat shrinkable tube the round state. not the measured data of the outer diameter and flattened.)
