A coaxial cable connector includes a body configured to be coupled with a coaxial cable, a nut having a forward end configured to be threadedly coupled with an interface port, and a sleeve surrounding the nut and extending forward from the nut in a direction opposite to the body. The sleeve has a forward portion that extends beyond the forward end of the nut by a length such that the sleeve is configured to contact an outer surface of the interface port before a center conductor of the coaxial cable contacts the interface port, and the sleeve is configured to align the connector with the port and to prevent the center conductor from contacting any portion of the interface port other than a center conductor contact portion of the interface port.
