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 Lined, Watertight Seal: When heated, a layer of adhesive/sealant shrinks and melts, permanently bonding and sealing the tubing to the wires; the adhesive lining of the tubing provides a good watertight seal around the wires
Thickened Walls for Protection Against Abrasion: When contracted, a fairly thick wall layer can be formed that is still flexible and not rigid like some heat shrink tubing; it also holds up well in abrasion situations, providing greater 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: 3/4 inch (20.0 mm) Heat Shrink Tubing Diameter (Rounded Condition): Get the exact diameter you need ;pictures show the inside diameter in the rounded condition, not the outside diameter and measurements in the flat condition
