Keep multiple colors of wrap wire on hand to color code connections in circuit boards for easy identification. This wire winds around a post terminal to make a strong electrical connection—no soldering needed. Lightweight and flexible, it stays in the shape you bend it for a tight hold. A silver plating shields the wire from corrosion as well as wear and tear. This wire has PVDF insulation, which resists breaking down from chemicals and melting up to 200° F. Because it’s insulated with PVDF, it’s commonly known as Kynar wire.

All of these assortments come with a wire stripper to cut and strip your wire. Store and organize the wire with the included dispenser box.

For an even tighter connection than wrapping by hand, use a wrap wire tool (sold separately). Thread the wire into the tip, insert the tool over a post terminal, and twist. Alternate between winding and unwinding by reversing the tip, just as you would a screwdriver bit.
