Abstract
The invention pertains to a coupling adapter for use with self-sealing valved coupling parts of the axially movable type for servicing and testing a fluid circuit. The adapter consists of a tubular body having a coupling end for connecting to the associated part and an axial passage wherein a threaded valve actuator is located having a free end adapted to releasably engage and displace the associated part's valve. A torque appling handle operatively associated with the valve actuator facilitates manual control of the valve's axial position.
