Heat Shrink HS216 tubing delivers reliable insulation and protection for electrical connections and components. This 1-meter length of blue tubing shrinks from 1.6mm to 0.8mm when heated, creating a secure, weatherproof seal around wires and joints. The HS216 grade ensures consistent shrink ratios and excellent dielectric properties, making it ideal for automotive, industrial, and telecommunications applications. Simply slide over your connection, apply heat, and watch it conform perfectly for professional-grade results every time.
