  • Publication number: 20230397799
    Abstract: A leakage test connector may comprise a male connector having an outer circumferential surface, a female socket connector that mates to the male connector, and an O-ring mounted about an inner circumferential surface of the fluid passage of the female socket connector. The male connector lacks an O-ring on the outer circumferential surface in an unmated state with the female socket connector. The male connector may also comprise a valve actuator pin, while the female socket connector comprises a pin that depresses the valve actuator pin. The valve actuator pin includes a top surface that is disposed flush with a tip of the male connector to minimize the likelihood of contamination on the male leakage connector.
