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.

When splicing wire in a wet environment I prefer to use butt splice connector with a considerable length of heat shrink tubing pulled over the splice after crimping. Unfortunately, my tool bag was out of splices that day when installing a replacement bilge pump. A quick trip to the local WM yielded a small pack (4) of heat shrink splices for an unreasonable price of around a buck apiece. I guess I'm used to buying in bulk with this sort of item, but even $0.50 would seem inflated to me.
As far as performance is concerned, I had trouble with one of the crimps holding and the seal of the tubing is questionable after heating with a heat gun. I will not be using these again and certainly will avoid using WM for this type of item in the future.

                  Butt connectors worked very well to seal the connections for the bilge pump. Applies a little heat and everything sealed up tight.

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