Solder-seal connectors across the full range of wire gauges, plus the extras that finish the job: a ProShield heat shrink tubing pack, a wire stripping tool, an AstraBeam™ penlight, a $50 store voucher, the Emergency Roadside Repair guide, VIP Insider Club access and priority shipping.
A crimp squeezes a metal barrel onto the strands. A solder-seal connector has solder, flux and adhesive-lined heat shrink built into one piece, so a single application of heat joins the metal and seals the joint at the same time.
A heat source. The stripping tool comes with the system, so bare wire to finished joint needs nothing else bought separately.
Yes, once heated properly. The adhesive lining seals against the wire insulation at both ends, which is what keeps moisture and corrosion out of the joint.
Because you are not reordering mid-project. It covers the full gauge range in one box, which suits a full vehicle rewire, a boat, or a workshop that goes through connectors regularly.
Automotive rewiring, marine electrical, trailers, and general workshop repairs — anywhere a joint has to survive vibration, heat cycling and damp.
No. There is no iron and no separate solder. Strip the wires, push them in, and apply heat until the solder ring flows and the sleeve draws in tight.
3–5 business days in the USA, and 7–10 business days everywhere else.
If you are not completely satisfied, we will make it right. Every SolderStick product is covered by a 30-day money-back guarantee, and our support team is there if you need them.
