Heat Shrink Tubing 4mm Black 1 Meter

The Heat Shrink Tubing 4mm Black comes as 1 meter of black tube with a 4 mm diameter, ready to cut into short sleeves for your wiring. When you warm a piece with a heat gun it shrinks tightly over the joint underneath, giving a clean, insulated finish. The 4 mm size sits between the thin and thick tubes and suits jumper wires, servo and sensor cables, and soldered splices on medium hookup wire.

What's in the Box
