This Ancor 47-piece adhesive lined heat shrink tubing kit, model 330101, is a great choice for various applications. It comes with black and red tubing in different sizes. There are 10 pieces each of 3/16' x 6', 1/4' x 6', and 3/8' x 6'. Also included are 5 pieces of 1/2' x 6', 3 pieces each of 3/4' x 3' and 1' x 3' in black, and 3 pieces each of 3/4' x 3' and 1' x 3' in red. Ideal for electrical insulation and protection.

To use this heat shrink tubing kit, first choose the appropriate size and color of tubing for your project. Slide the tubing over the area you want to insulate or protect. Then, use a heat source like a heat gun to apply heat evenly around the tubing. As it heats up, the tubing will shrink and the adhesive inside will melt, creating a tight and secure seal. When using the heat gun, keep it moving to avoid overheating and damaging the tubing. Make sure to wear heat-resistant gloves to protect your hands. Store the kit in a cool, dry place to maintain the quality of the tubing. If the tubing gets dirty, you can gently wipe it with a clean, dry cloth.
