Insert. Heat. Done.
Push both wires in
Strip both ends, pick the colour that matches your wire gauge and push the strands in so they meet under the solder ring.
Heat for 10–15 seconds
The ring flows into the strands while the tube shrinks tight around the joint.
Sealed for good
Both ends seal on the insulation. Let it cool 10–30 seconds, then give it a tug.

Before you order
When does the Christmas price end?
Order by Monday 14 December at 11:59 PM Pacific for delivery by Christmas in the US. The Christmas price runs until Friday 25 December.
Which AWG sizes are in the 500 kit, and how many of each?
500 connectors in four colour-coded sizes:
26–24 AWG · 0.25–0.34 mm²
22–18 AWG · 0.5–1 mm²
16–14 AWG · 1.5–2.5 mm²
12–10 AWG · 4–5 mm²
Match the colour to your wire gauge.
500 or 250, which should I get?
For one project, 250. If you work on more than one vehicle, boat or trailer, the 500 works out cheaper per connector and you won't run short of the sizes you use most.
What do I heat them with?
A heat gun. Hold it a few inches away and keep it moving until the ring has flowed and the tube is flat.
How fast does it ship?
Usually 3–5 business days in the US and 7–10 business days worldwide.
