Heat Shrink Tubing 3mm Black 1 Meter

The Heat Shrink Tubing 3mm Black comes as a 1 meter length of black tube with a 3 mm diameter. Cut a piece, slide it over a solder joint or wire splice and warm it with a heat gun: it shrinks tightly around the wires to insulate and protect them. The 3 mm size suits jumper wires, hookup wire, LED and resistor legs, and thin sensor and servo cables.

What's in the Box

• 1 × 1 meter of 3 mm black heat shrink tubing

Tip: Slide the tubing onto the wire before you solder the joint, and cut each piece about 1 cm longer than the bare area. Use a heat gun rather than an open flame for an even shrink without burning the tube, and choose a larger size for thick cables or connectors.
