SolderStick Waterproof Connector Kit – Universal Heat-Shrink Solder Wire Butt Connectors – AWG 0-6 – Car & Boat

Stop messing with crimpers that slip.

These SolderStick connectors are the shortcut you needed.

Just stick the wire in, hit it with heat, and bam—waterproof sealed connection.

Kit covers AWG 0 through 6, so thick battery cables and thin signal wires both covered.

Multicolored, PE insulation, solid tinning.

Great for car audio, marine, trailer wiring.

MPN doesn’t apply, brand unbranded, but they work exactly like the name-brand stuff.

Keep a set in the glovebox.
