400 PCS Heat Shrink Tubing Kit, Heatshrink Sleeving Kit, Larger Diameter, 3:1 Dual Wall Tube, Adhesive Lined, Wire Cable Repair Sleeve, Black Red

3:1 Shrink Ratio: Heat shrink tubing 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, creating waterproof and long-lasting insulation. Variety of Sizes: We have included larger diameter heat shrink tubing ranging from 1/8" to 1". Shrink tubing is precut to 1.75 inches. Easy to Use: Simply slide the heat shrink tube over your connection point and apply heat. Professional connections made in seconds. Dual Wall Tubing: Outer wall of the heat-shrink tubing provides abrasion resistance. Inner wall creates waterproof seal and strain relief.
