Sealed connectors serve as specialty-type terminals. These connectors are designed to allow multiple wires to be connected into one single terminal, ensuring that electrical current is being transferred without an additional conduit. When matting two wires with one, these connectors replace either standard wire connectors or quick splices. The added heat shrink around the terminal facilitates in making a secure electrical connection, and to make the connection waterproof. Sealed connectors are commonly used in automotive and marine vehicles, but can also be used in other various electrical applications to protect against harsh environments and contaminants.
