Heat Shrink Butt Connectors

Heat shrink connectors offer heat activated adhesive built into the sleeve of the heat shrink tubing. When heated, these connectors form a watertight seal and the ultimate vibration and strain relief. 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.

    Fantastic product, clear plastic makes it easy to see wire penetration. Then being able to shrink create a weather proof splice.
