Adhesive-lined heat shrink connectors are ideal for bilge pump and switch leads or any area exposed to moisture.

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.

      Comments about Heat Shrink Butt Connectors:

      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.

        Comments about Heat Shrink Butt Connectors:

        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.

            Clamped well, did nopt shrink as much as neeed. Used liquid shrink wrap (Think very liquid contact cement, the color of black electrical tape that dries in 45 seconds) to finish the repair..

            Comments about Heat Shrink Butt Connectors:

            These are great to use anywhere but the heat shrink material is easy to nick when crimping wire. I also then coat with liquid electric tape to completely seal.

                Pulled my boat out of storage and got it ready for the year. As I began testing my electrical systems, nothing worked. I troubleshot each individual system to the helm switches and knew they all needed to be replaced. I took my time replacing them all and replaced each non-marine connection with new marine butt connectors for the specific applications.

                  Salt air is your worst enemy for ground wires in boats. It's so much easier to use the right stuff to begin with. It will prolong the time before you have to do it again. Because you will have to do it again anyway.
