BUT dis-similar metals are dis-similar. You can never be sure. And you can not trust what stuff is labeled as in today's made in China for as cheap as possible crap. High price is no guarantee either.

That's why I like plastic - absolutely no electrolysis issues and PVC it tough stuff. Marelon is even tougher. Nylon dries out and gets brittle so stay away from it or use it in a pinch and plan to replace it.
