Coupling assemblies for connecting fluid-carrying components

An apparatus comprising:

• one fluid-carrying component;
• an other fluid-carrying component;
• and
• a coupling assembly to connect the one fluid-carrying component to the other fluid-carrying component, the coupling assembly comprising:
• a socket fitting secured to the other coolant-carrying component and comprising an opening in fluid communication through the socket fitting with the other fluid-carrying component, the opening being sized to accommodate a portion of the one fluid-carrying component therein;
• a sleeve, the sleeve encircling the socket fitting, with the socket fitting residing fully within the sleeve and the sleeve being rotatable relative to the socket fitting, the sleeve comprising a first locking feature;
• a second locking feature associated with the one fluid-carrying component, the second locking feature being positioned and sized to engage the first locking feature when the one fluid-carrying component is inserted into the opening within the socket fitting, and wherein, once engaged, rotating of the sleeve locks the first and second locking features together to secure the one fluid-carrying component to the socket fitting;
• wherein the first locking feature comprises first locking threads, and the second locking feature comprises second locking threads, the first locking threads being internal locking threads within the sleeve, and the coupling assembly further including an external threaded ring secured to the one fluid-carrying component, the external threaded ring comprising the second locking threads and the external threaded ring contacting an end surface of the socket fitting with locking of the first and second locking threads together;
• and
• wherein the socket fitting comprises at least one annular groove in the end surface thereof contacting the external threaded ring with locking of the first and second locking threads together, the at least one annular groove accommodating, in part, at least one annular face seal, the at least one annular face seal engaging and compressing against the threaded ring when the first and second locking threads are threadably locked together to form a fluid-tight seal between the one fluid-carrying component and the socket fitting.
