We get a lot of confusion about which plug or terminal is needed based on female vs male. People read a forum post and then purchase the wrong side for their project. We thought we'd do a short post and define what it means when someone says a male plug or female terminal. As for the seals, they are typically the same for both the plug and receptacle, we'll call them unisex :)
Male - a male connector refers to the plug side.
Female - a female connector refers to the receptacle side.
Male - a male terminal refers to the terminal or pin that is inserted into a female receptacle.
Female - a female terminals refers to the terminal or pin that is inserted into a male plug.
