10-12-14 deep well pump cable splice kit comes with 4 x butt connectors and 4 x 3M™ clear dual wall heat shrink tubing that are suitable for connecting #10, #12 #14 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 connecting a submersible deep well water pump and other water tight applications.
Instructions come with the kit. Made in USA
