The invention discloses a sealing test device for a separation and stripping electric connector socket. The sealing test device for the separation and stripping electric connector socket comprises an air charging device, a pedestal, a cover plate, a container, a sealing pad and a connecting mechanism, wherein a three-layer sealing base is arranged in the pedestal; the cover plate is connected with the pedestal through the sealing pad; an air inlet is formed in the side wall of the pedestal; the air charging device is connected with the air inlet through a first pipeline; an air outlet is formed in the side wall of the cover plate; the container is connected with the air outlet through a second pipeline; the connecting mechanism is positioned in the cover plate; and the connecting mechanism is connected with the three-layer sealing base. The sealing test device for the separation and stripping electric connector socket solves the problem that the sealing property of one of two layers cannot be detected after the front layer and the back layer of the sealing socket are filled with glue in the prior art.
