RS PRO uninsulated crimp ring terminals are electrical connectors used to terminate or connect wires in various applications. Unlike insulated terminals that have a protective covering or sleeve, uninsulated crimp ring terminals consist only of a metal ring without any insulation. These high-quality uninsulated crimp ring terminals are also known as a ring connector or cable lug. Ring crimp terminals are used for connecting an electrical cable or wire to a stud or a post on an electrical component such as a battery terminal. This ring terminal is made from highly conductive copper with a brazed seam for maximum electrical conductivity and corrosion resistance.
