Well Pump Wire Splice Kit, Submersible 3M Dual Wall Heat Shrink Tubing and Copper Connector for 4 Wires, #10 #12 #14 AWG.
This wire splice kit comes with 4 x butt connectors and 4 x 3M clear dual wall heat shrink tubings that are suitable for connecting #10 #12 or #14 pump wires.  The tubing used in these kits was developed especially for groundwater applications. The inner wall of a special thermoplastic adhesive melts and flows when heat is applied. The tubing rapidly shrinks to a skin-tight fit, forcing the melted adhesive to flow and cover the substrate.  Upon cooling the adhesive solidifies, forming a permanent flexible, waterproof barrier. The clear tubing allows the additional advantage of seeing inside the splice.Ideally using for splicing a submersible deep well water pump and other waterproof applications.Instructions come with the kit.
