Solder and seal a wire join in one step, with no soldering iron, no separate heat-shrink and no electrical tape. Each connector has a low-temperature solder ring in the centre and adhesive-lined heat-shrink at both ends. Slide it over your wires, hit it with a heat gun, and the solder bonds the conductors while the tubing shrinks into a tidy, waterproof joint. Choose your wire size by colour below. Sold individually with a 10-piece minimum, and the more you buy, the less you pay per connector.


  • Solder + seal + insulate in a single step
  • No soldering iron needed, just a heat gun
  • Waterproof, dust-proof adhesive-lined seal
  • Low-temp solder ring melts at ~138°C
  • Clear sleeve lets you see the solder flow
  • 7 colour-coded sizes from 26 to 8 AWG
  • Buy more, pay less with automatic bulk pricing
  • Stocked and dispatched fast from NZ

How to use them

  1. Strip & overlap

    Strip ~8mm off each wire and twist or overlap the bare strands together in the centre.

  2. Slide the connector on

    Centre the solder ring directly over the join so the bare wires sit inside it.

  3. Apply heat

    Play a heat gun evenly around the connector. The solder ring melts and flows into the wires first.

  4. Seal it

    Keep heating until the coloured bands and tubing shrink fully and a little adhesive weeps from the ends. That is your waterproof seal. Let it cool.

Good to know: Use a proper hot-air heat gun for the best seal and rotate it around the connector so the whole joint heats evenly. Stocked and dispatched fast from our Te Awamutu base, at overseas prices without the overseas wait.

Frequently Asked Questions

Answers to the questions buyers ask most.

Do I need a soldering iron?
No. These are designed for a heat gun (around 250-300C). The built-in solder ring does the joining for you, so you never touch an iron. A lighter or torch can work in a pinch, but a heat gun gives the cleanest, most even result.
Why is there a 10-piece minimum?
These are small, low-cost parts, so we sell them in a minimum of 10 to keep per-connector pricing low and shipping worthwhile. The price per connector drops automatically as you pass 25, 50 and 100 pieces.
Are they really waterproof?
Yes. The heat-shrink tubing is adhesive-lined, so as it shrinks it melts a glue that flows around the wire and seals both ends, giving a water- and dust-resistant join suitable for automotive, marine, trailer and outdoor use.
Which colour/size do I choose?
Match the colour to your wire gauge: White 24-26 AWG, Red 18-22 AWG, Green 16-18 AWG, Blue 14-16 AWG, Purple 12-14 AWG, Yellow 10-12 AWG, Orange 8-10 AWG. If you're between sizes, pick the one that fits snugly over the stripped, twisted wires.
What temperature melts the solder?
The low-temp solder ring flows at roughly 138C, below the temperature needed to fully shrink the tubing, so the solder bonds the conductors first and the waterproof seal forms as you finish heating.

Why Buy from NZN

Useful parts, fair prices and someone local to help.

I'm Lukas, an engineering student and maker based in Te Awamutu. NZN grew out of a CNC build that dragged on for months because every missing cable, bolt or electronic part meant another overseas order. I started the shop so Kiwi makers can spend more time building and less time waiting for the next parcel.
