DESCRIPTION

For marine connections or anywhere you need a guaranteed electrical connection that will be immune to oxidation and corrosion, my new favorite go-to is solder seal connectors.  Haisstronica makes the best ones I've found - the solder doesn't melt under normal current and the joins are incredibly strong and waterproof.  Great for boat, RV, automotive, and more.  Use anywhere you'd use a mechanical butt splice connection.
