Claim 1:
2. The coupling system of claim 1, further comprising the female coupling device, wherein the female coupling device is configured to releasably receive the male coupling device in a pre-coupled position, a partially-coupled position, and a fully-coupled position, and wherein the female coupling device includes:
a female main body defining a maximum exterior circumferential surface of the female coupling device, a female opening at a front-most face of the female coupling device that is configured to receive the front face and exterior circumferential surface of the male coupling device, and an interior bore configured for fluid communication with the interior fluid passageway of the male coupling device;
a forward bore seal seated in a forward groove along the interior bore and radially inward from the maximum exterior circumferential surface of the female coupling device;
a stem that includes a stem head carrying a stem seal and defining a stem front face that is oriented toward the front-most face of the female coupling device;
a rear bore seal positioned rearwardly of the forward bore seal in a rear groove along the interior bore of the female main body and positioned radially outward of the stem seal; and
a movable sleeve slidable within the interior bore relative to the stem head so that the stem seal is releasably engageable with an interior circumferential sleeve surface of the sleeve, wherein the movable sleeve is slidable in a longitudinally rearward direction to simultaneously disengage from the stem seal and the rear bore seal in response to movement of the male coupling device from the pre-coupled position toward the partially-coupled position, wherein the stem seal is spaced apart from the movable sleeve and the male coupling device in response to the female coupling device releasably receiving the male coupling device in the fully-coupled position.
