Allstar PerformanceALL76131 Solder Slug for 2 Gauge Terminal, (Pack of 10)

I needed some of these for 0ga power wire I used 2 in it with he torch lighter works better then 0ga ring terminal with crimp job big save and sounds better some how

These are a bit expensive but worked well on copper battery ends. I preheat the end, drop one in, heat it a bit more, preheat the wire, put the wire in and heat one last time until the pill melts and coats the wires.

I had used these successfully from another supplier, but these seem to have an inconsistent melting point

I just learned about these and it's a game changer! Beats trying to crimp it or even worse, using the clamp style. This is like a factory connection and much easier.

worked great for my battery cables

Easy and quick. Solid connection for my winch cable.

I have been using a hydraulic crimper to put connectors on heavy gauge wire. Everybody says soldering the connectors will provide better contact. When I saw these I had to try them. Piece of cake to use. Clamp the fitting or connector in the vise with the open end pointing up. Drop in the solder plug. Strip off the right amount of insulation from the cable. Heat up the fitting with a torch. When the plug liquifies jam your cable in and hold until the solder hardens.

They’re great and makes the most secure connections
