Heat Shrink Tubing 4mm Red 1 Meter

The Heat Shrink Tubing 4mm Red is a 1 meter length of red heat shrink tube with a 4 mm diameter. When heated, it shrinks around solder joints and wire ends to insulate and protect them. The 4 mm size suits common hookup wires and small connections in hobby electronics, and the red colour helps you mark positive lines.
