Heat Shrink Tubing Roll - 3:1 Shrink Ratio - Black - 50 Ft

3:1 SHRINK RATIO - Recovers to 1/3 of its original diameter, and makes a tight seal. Eliminates the problem of 2:1 tubing not shrinking tight enough. GLUE INSIDE - When heat is applied, adhesive comes out and seals the connection. This creates a resistant and long-lasting insulation. EASY TO USE - Simply slide heat shrink tube over your connection point and apply heat. Make professional insulated connections in seconds. DUAL WALL TUBING - Provides enhanced protection from wear and tear. Industrial grade tubing is resistant to fluids, heat, and mechanical stretch.
