Waterproof and Insulation Solder Wire Connectors When the butt connector is heated and melt down,the dual wall hot-melt adhesive flows,it push the air out and fills any gaps between the wire and the butt connectors which makes the connetion waterproof.Polyolefin tubing provides insulation and flame retardant. Easy to Insert&Safe  The transparent shell can see the inside to facilitate the connection of wires.Avoiding arcing and make wiring safer.  Step to Use: 1.Penetrate the butt connector to one of the wires and then twist the two conductor together. 2.Move the conductor to the middle solder(Note:the conductor can not exceed the color mark at both ends).   3.Apply heat to the solder with a heat gun until it melt with the conductor ,then heat the tube on both sides to wrap the wires.
