About this item

• 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, creating waterproof and long-lasting insulation.
• VARIETY OF SIZES – We have included 7 most commonly used diameters ranging from 3/32″ to 3/4″. Shrink tubing is precut to 3.5 inches.
• EASY TO USE – Simply slide heat shrink tube over your connection point and apply heat. Professional connections made in seconds.
