I've never been a big fan of butt connectors because they can pull apart if not crimped just right. BUT....These butt connectors are the best! Easy crimp connections as usual. THEN......pass a torch or heat gun over them and they shrink down around the insulation....AND....the hidden glue is activated. You can see the semi-flexible glue come out of both ends of the connector. So the connection is perfectly sealed and water-tight. The two wires are NOT going to pull out of these connectors.

These things do not shrink down to fit snugly even when a lot of heat is applied, thus are not water-tight and not weather resistant. The regular heat-shrink tubing works much better in my opinion, and it's quite a bit cheaper.

                      Lots of people use non marine grade wire butt connectors but as a marine surveyor, your asking for a prime hidden spot for corrosion inside a connector that doesnt heat shrink and adhesive seal like these do. Swap out all the old ones and prevent problems before they happen.

                        When these are properly crimped and heated they are bullit proof. Select the right size for the wire used. Take your time stripping the wire without nicking the strands. Rotate the connection while heating evenly.
