An access port for a fluid system having a sidewall defining a fluid cavity is provided. A probe receiver, having an inner passage with a valve seat and a chamber adjacent to the valve seat and in fluid communication with the inner passage, is connected to the sidewall of the fluid system. The chamber has an opening in communication with the fluid cavity and a valve member biased to a seated position that moves within the chamber to an unseated position. A probe is connected to the probe receiver and extends through the inner fluid passage of the probe receiver into the chamber. When the probe body is inserted into the probe receiver it moves the valve member to the unseated position and the valve member and a portion of the probe body traverse the opening. When the probe body is removed, the valve member returns to the seated position.
