Heat Shrink Tubing 1m

A soldered wire splice with just electrical tape wrapped around it eventually loosens, unwraps, or lets moisture in - heat shrink tubing solves that permanently, sliding over the joint before soldering and then shrinking down tightly around it with a heat gun or lighter flame, forming a snug, semi-permanent insulating layer that tape simply can't match for durability. Once shrunk, it stays put and resists the kind of gradual unraveling that eventually happens to taped connections.

Available in red, yellow, or black, color coding a wire splice or connection point becomes straightforward - matching standard wire color conventions (red for positive, black for ground) rather than every joint looking identical under plain black tape. At 1 meter per piece, there's enough length to cut many individual small pieces for a full project's worth of connections rather than running out partway through a build.

Common uses are insulating and protecting soldered wire splices, color-coding cable connections and joints for easy identification, and general wire and connector protection in any electronics project involving custom wiring.
