4mm Heat Shrink Tube Black - 1 Meter
High-quality 4mm diameter black heat shrink tubing, sold in a convenient 1-meter length. Ideal for insulating solder joints, bundling wires, and providing strain relief in electronics, automotive, and DIY projects. Shrinks to approximately half its original diameter when heated, creating a tight, protective seal around cables and connections.

Frequently Asked Questions
What wire gauge does 4mm heat shrink fit?
4mm heat shrink tubing comfortably fits over wires and cables up to approximately 3.5mm outer diameter before shrinking. After shrinking, it grips components as small as ~2mm. It works well with standard hookup wires, multi-strand cables, and small connectors.
What tools do I need to shrink it?
A heat gun is recommended for the best results. You can also use a lighter (carefully), a soldering iron held near the tube, or a hot air rework station. Apply heat evenly and rotate for a uniform shrink.
Is it safe for electrical insulation?
Yes, polyolefin heat shrink tubing is specifically designed for electrical insulation. It is flame retardant and provides reliable dielectric protection suitable for low-voltage and signal-level applications.
Can I use this outdoors or in humid environments?
Yes, once properly shrunk, the tubing provides excellent moisture and environmental resistance. For fully waterproof seals, consider adhesive
