Qualtek Electronics QD Series Adhesive Lined Heat Shrink Tubing features a 4:1 shrink ratio that allows it to easily fit a wide range of components. This tubing is specifically designed to protect splices and the joining of wire harnesses against environmental damage. The thick adhesive-coated layer forms an effective barrier against fluids and moisture, while the tubing itself is flame retardant and UV resistant. Qualtek Electronics QD Series Adhesive Lined Heat Shrink Tubing offers an operating temperature range of -40°C to +130°C and a minimum shrink temperature of +110°C.
