Detail Product

Have you ever thought it can be so simple to connect two wires together? Here is the simplest and best solution for you. These Waterproof Solder Wire Connectors are made to allow people to connect wires without any technical background.

Solderless & Crimpless, all you need is just a heat gun to finish the connection, much faster and easier than the traditional way. Simply place the two stripped wires into the solder sleeve and apply heat to finish the connection. The solder will gradually flow, and the insulation tubing will shrink down, creating a durable seal.

Polyolefin tubing outside and hot melt adhesive inside would effectively improve the waterproof performance of these solder connectors. Perfect for your working on boat, vehicle, home or scientific wiring projects.
