4:1 Shrink Ratio: Shrinks to 1/4 of its original diameter, and makes a tighter seal. Eliminates the problem of 2:1 tubing not shrinking tight enough.
Dual Wall Tubing: Outer wall provides abrasion resistance. Inner wall creates resistant seal and strain relief.
32.8FT Roll: 1/4 INCH (6mm) in diameter. A roll of shrink tubing will last through many projects.
Easy to Use: Simply slide heat the shrink tube over your connection point and apply heat. Professional connections in seconds.
