Heat Shrink Dual Color Tubing is a type of heat shrink tubing that changes color when exposed to heat. These tubing are commonly used to insulate wires, protect them from abrasion, and provide strain relief.

The two-color design of these tubes makes it easy to identify wire connections. When heated, the tube shrinks to fit the wire, and the color change indicates a secure connection. There are different types of heat shrink two-color tubing on the market, such as red and black, blue and yellow, etc. They have different sizes and shrinkage rates.

Just like other heat shrink tubing, the Green and Yellow Dual Color Tubing shrinks when heated, providing excellent insulation and strain relief for the wires underneath. It also has an indicator that changes color as it shrinks, making it easier for people to tell if the tubing has shrunk sufficiently.
