Electrical tape on a splice looks fine for a week, then the adhesive goes gummy and the tape unwinds. Heat shrink tubing is the proper way to insulate a soldered joint: slide a piece over the wire before you solder, push it over the joint afterwards, and shrink it tight with heat.

The catch is always having the right size on hand. This kit has 12 sizes sorted in one box, from thin 1 mm tubing for small signal wires to 13 mm for thick cables and bundles.

Pro tip Slide the tubing onto the wire before you solder, and keep it well away from the joint while it cools. It’s easy to finish a perfect joint and only then notice the tubing still on the table.

Why we like it

✓900 pieces in 12 sizes, from 1 mm to 13 mm
