Just made some new 12 gauge speaker wires for my home theater setup. I terminated the wires with Sewell Silverback double set screw type bananas. Cranked on the set screws to get as gas tight a connection as possible. Disassembling an existing connection illustrates that I've made a solid impression in the stranded wire, so I would think this has to be quite tight. I think the plugs are pretty robust already, but...
I was thinking of putting a few drops of epoxy into the back of the plugs for two reasons:
1. This will bolster the mechanical connection so I probably will never have to worry about having to redo the connection.
2. This will effectively make the entire connection air tight, so any exposed copper should take a very long time to oxidize. In fact, if there isn't enough oxygen in the remaining air pocket, it will never oxidize.
Basically, this would result in permanent cables, assuming the gold plating on the bananas never corrodes. My question is whether the epoxy will change the resistivity and/or impedence of the plug in any way? I'm assuming, if I crimped down hard enough, the epoxy will not penetrate the seal between the set screw and the copper wire core...
Any thoughts? No need to tell me this is overkill...I know.
