Description

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. Made in the USA

  • Best submersible well splice kit I've ever used.
These kits work extremely well. The metal crimp piece is heavy duty to make the splice yet the crimp piece crimps easily. The heat shrink tubes are fabulous. They are thick, shrink well made, and at the end of the heat sealing process, a sticky sealant is released from the inside of the tube just as it tightens up to make an excellent water tight seal. If you need to do a double splice because your wire ends don't meet, the heat shrink tubes will shrink and seal over a previous tube that has already been sealed. Very effective, easy to use product. Compared to the compression tubes, I think this is far better. You always have to worry about the gasket on the compressed ends of the tube getting a good seal. They require more tools to install and are bulkier. 3M's splice kit is so easy to use and seals a longer length of the connecting wires, not just at a narrow compressed gasket. ... show more
