Heat shrink male bullet connector for 16–14 AWG stranded copper wire, with a .157" diameter bullet. Tin-plated pure copper with a brazed barrel for uniform crimping and vibration resistance. Its adhesive-lined dual-wall heat shrink sleeve (3M Type MW polyolefin) seals around the wire when heated, keeping out water, salt and road spray. Rated -55°C to 125°C (-67°F to 257°F).
Use it for: connections you want to unplug for service — lighting, horns, fans, pumps and accessory circuits in boats, trailers and trucks, and anywhere the connection sees water.
How it connects: a male bullet plugs into a female receptacle of the same bullet diameter — .157" and .180" are separate sizes. Mates with the heat shrink female 16–14 AWG .157"; other .157" female receptacles: heat shrink female 22–18 AWG .157" · nylon female 16–14 AWG .157" · nylon female 22–18 AWG .157" · vinyl female 16–14 AWG .157" · vinyl female 22–18 AWG .157". Crimp with a tool made for insulated terminals; then heat the sleeve evenly until it shrinks and a little adhesive shows at the ends.
Other options: Same size in nylon, vinyl. For a splice that doesn't need to unplug, use a butt connector.
