16-14 gauge male Weather-Pack terminals #12124582. Use these round pin and socket terminals, housings, and seals to make economical connections that can handle harsh environments. Each connection requires a male and female terminal, a seal for each terminal, and a male and female housing. Pick terminals that match your wire size, then choose a housing that offers the number of connections you'd like to make. All terminals work with all housings, regardless of wire size. Terminals require two crimps (terminal to wire strands, terminal to seal to wire insulation). A proper crimping tool is required. For heavier usage, use a tool that performs both crimps at the same time.
