22-18 gauge 0.250" width, 0.032" tab female fully insulated heat-shrink quick-disconnect terminals. Also known as slip-on or fast-on connectors, these quick-disconnect terminals offer the fastest way to connect and disconnect two wires. They are also reusable. Simply slide the male terminal into the female terminal. The full insulation provides a "mini-enclosure" for where the two contacts meet, keeping liquids and contaminants away from the electrical connection. For use in harsh environments, these terminals feature a heat shrink connection that also has an internal sealant. After crimping the terminal onto the wire, simply apply heat. Keeps moisture out while ensuring your wire does not pull out of the terminal. Requires one crimp plus heat.
