250 Solderstick solder seal wire connectors in four colour-coded sizes, packed in a storage box. Join, insulate and waterproof a wire joint in one step.

Each connector has a ring of solder in the middle and a glue ring at each end, inside a heat shrink sleeve. Strip the wires, twist them together, slide the connector over the joint and heat it. The solder joins the wires, the sleeve shrinks tight and the glue rings seal both ends. A heat gun is all you need: no soldering iron and no crimper.

  • IP67 rated waterproof seal once heated
  • ISO 9001 certified manufacturing, CE marked
  • Covers wire from 0.25 to 6.0 mm² (AWG 26 to 10)
  • Holds up to vibration and movement in vehicles and boats

The problem it solves

Most wiring faults start at a bad joint. Crimps work loose with vibration and corrode once water gets in. Electrical tape peels off in the heat. Soldering properly means an iron, solder, heat shrink and a power point, which you rarely have under a dash or on a boat ramp.

A Solderstick does all three jobs at once. The solder ring melts and joins the wires, the sleeve shrinks tight to insulate them, and the glue rings seal both ends. You get a soldered, sealed joint with just a heat gun.

Who it's for

Cars and utesAdd lights, fix a broken wire or fit a dash cam without cutting into the loom with crimps.
4WD and caravansJoints that survive corrugations, dust and creek crossings.
Boats and jet skisSealed joints for bilge pumps, nav lights and fish finders, where salt water kills crimps.
TrailersLighting plugs and tail lights that keep working after being dunked at the ramp.
Solar and 12 VTidy, sealed joints for batteries, fridges and lighting.
Workshops and hobbyistsQuick repairs on tools, appliances, models and electronics projects.

Which size do I need?

Match the connector colour to your wire size. The size is usually printed on the wire's insulation.

White40 in this kit

0.25 to 0.34 mm² · AWG 26 to 24

Sensor, signal and electronics wire

Red100 in this kit

Not sure? Red and blue cover most automotive jobs, which is why the kit holds the most of those.

What's in the box: 250 connectors in a storage box: 40 white, 100 red, 90 blue and 20 yellow.

How to use it

  1. Slide onSlide the connector onto one of the wires.
  2. TwistStrip both wire ends, then twist or intermix them together.
  3. CoverSlide the connector back over the joint so the solder ring sits in the middle.
  4. HeatHeat the solder ring first until it flows, then each end until the sleeve shrinks and seals.

Questions before you buy

Do I need a soldering iron?

No. The solder is already inside the connector. A heat gun melts it and shrinks the sleeve in one go.

Can I use a torch instead of a heat gun?

A small butane torch works. Keep the flame moving so the sleeve doesn't scorch before the solder melts. A heat gun is the easiest option.

What heat gun do I need?

Any hot air gun works, including cheap hardware store ones. Small battery heat guns are handy for working in the car or on the boat.

Is it as strong as a normal solder joint?

Yes. It is a solder joint, with heat shrink and glue sealing over the top. Watch the review videos on this page to see them tested.

Does it work on solid and stranded wire?

Yes, as long as the wire size matches the connector colour.

Can I join two different wire sizes?

Yes, if both fall inside the range for that colour. Pick the colour that suits the larger wire.

Can I reuse a connector?

No. Once the solder has flowed, the joint is permanent. To undo it, cut it out and use a new one.

Four steps

How to use it

  • STEP 1: Slide the connector onto one of the wires

  • STEP 2: Twist or intermix the two stripped wire ends

  • STEP 3: Slide the connector over the joint

  • STEP 4: Heat the solder first then the ends

FAQ

Frequently asked questions

  • From the Gold Coast, Queensland. Orders placed before 1pm ship the same day by Australia Post Express. Prices are in Australian dollars and include shipping. We ship within Australia only.

  • Every order goes by Australia Post Express. Inside Australia Post's Express network most orders arrive the next business day. Elsewhere allow 1 to 2 business days in Queensland and 1 to 3 interstate. Check your postcode on Australia Post.

  • Contact us through the contact page and tell us whether you'd prefer an email or a phone call. We'll get back to you and sort it out.

  • Anyone working on low voltage wiring: car, ute, 4x4, caravan, boat and truck owners, auto electricians, marine techs, solar installers, farmers and hobbyists.

  • You need a heat gun or a small butane torch.

    1. Slide the connector onto one of the wires.
    2. Strip both ends, clean them if they're dull, then twist them together.
    3. Slide the connector over the joint so the solder ring sits over the twist.
    4. Heat the solder ring until it melts and flows into the wires, then heat each end until the glue rings seal.

    For extra protection, slide a piece of dual wall heat shrink over the finished joint.

  • A heat gun, or a small butane torch. If you use a torch, keep the flame moving so the tubing doesn't scorch before the solder melts.

  • No. You'll get a good joint without it. On old or tarnished wire, a little flux and a quick preheat help the solder flow right through the joint.

  • Yes. Once heated, the glue rings seal both ends and the joint is IP67 rated. For joints that sit in salt spray or get knocked about, add dual wall heat shrink over the top.

  • Light bars and spotlights, trailer plugs, fridges and dual battery setups, bilge pumps and nav lights, reversing cameras, car audio, solar leads, and quick repairs on farm and workshop gear. Any 12 or 24 volt joint that has to stay dry.
