Abstract: A fluid coupling for connecting a hose to a port includes an internal body slidably supported in an external body bore of an external body. The internal body includes valve bore. A stem, located in the valve bore, includes first and second stem seals, and a stem bore in fluid communication with a hose fitting and an outer surface of the stem between the seals. The stem is movable between valve open and closed positions by moving a valve handle. A rotation limiting member coupled to the stem and slidably coupled to the external body limits the rotation of the stem. A locking sleeve coupled to the external body moves between a secure position and a release position. The locking sleeve interferes with the valve handle position when the locking sleeve is in the release position to prevent opening the valve when not connected to the port.
