16-14 gauge 0.180" diameter male heat-shrink bullet terminals. 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. Often used as a substitute for quick disconnect terminals due to their ability to quickly mate and their reusability. Simply slide the male terminal into the female terminal. Requires one crimp plus heat.
