Review on Ancor 320125 Shrink Connector 22 18 by Darnell Golden

This is much better than cheap connectors for sealing boat or trailer wires, especially where two wires meet one or where wires of different sizes meet. For best results, use an ancor cutter. You can also apply liquid tape to this connector for added protection. It's worth paying a little more for cutters and connectors instead of constantly reworking connections because of water ingress.
