Heat Shrink Tube is required when you want to build your wiring harness to be resistant to abrasion, scrubbing and provide insulation to stranded and solid wire conductors, joints, connectors and terminals in the electrical systems. It is a plastic tube which shrinks rapidly when exposed to heat which can be given by a heat gun or even a lighter though not recommended! It tightens around a conductor to keep it firmly in place and restrict its movement.

The material used is PVC which can withstand heat up to 125ᵒC and provide a wide range of colors and also clear tube if required. The shrinking ratio is 2:1 i.e., it will shrink to half its size when heated. This 8mm diameter tube will shrink to 4mm diameter tube after shrinking. This protection of heat shrink tube allows the wires to be used in areas where they are exposed to moisture, chemicals and dust particles as it protects the conductor from coming in contact with them. You can also use different colored Heat Shrink tubes to color code different sections of harness.
