Racers Edge Solder Tubes allow for fast and easy wire repairs at the track, flight line, or workbench without a soldering iron. Simply choose the appropriate size, place the unshielded wires to be soldered in the center of the tube, and shrink the tube using a lighter (good) or heat gun (better). Not only are the wires bonded with solder, but the protective clear tubing is held in place with a shrink band. Sold 6 per package.
