How to Use

Slide heatshrink over the wire before soldering. After soldering the joint, slide the tube over it and apply heat from a heat gun or lighter (keep moving to avoid burning). The tube shrinks to grip the wire tightly. The 4mm size covers most single-core sensor wires; 6mm and 8mm handle thicker motor cables and multi-conductor bundles.
