What you need if you have to connect aluminum wiring to copper. Seriously expensive compared to standard wire nuts but safety comes at a cost.😳😳

We needed these for a renovation and couldn't find them at three local hardware stores, turned to Amazon and had them in a couple days. Completed our project perfectly.

The connectors are now very expensive because aluminum wire hase not been used in houses since the early 70's. These are for aluminum to copper wire connections.

Its important that you get this style when connecting Aluminum to copper connections. Please note this particular set holds very few wires. Especially since Aluminum tends to be larger wire. If you need alternate sizes your local electrical supply store will have them if Amazon doesn't.

These are very good quality and useful ! I use them with anti-oxidant joint compound and it has paid for itself ! Great value for the money !

These connectors are worth their weight in gold.

These are the same as what you get at the big box stores, only cheaper. Used to connect aluminum and copper wiring. These are special because they are filled with ox-guard or other brand name of black nasty material that helps contain the wire connections and reduce chance of fire. Copper and aluminum wiring expands and contracts at different rates and arching can occur leading to fires. These are rated to prevent this from happening.
