The Alphacool ES quick release coupling set IT/IT is designed for permanent mounting on a PC or server case and works like a bulkhead fitting. The quick release coupling enables quick connection or disconnection of externally connected radiators or cooling systems.
Mounting
The quick-release coupling set is mounted in two openings in the casing, each with a diameter of 18mm (see mounting example). Male and female connectors are inserted with the threaded side through the round openings and screwed tight with the enclosed lock nuts. The water circuit is then connected on the inside of the case via the two G1/4" internal threads. External radiators or cooling systems can now be easily connected to the water cooling in the housing by using additional quick-release fasteners.
Accessories
The quick release coupling set comes with a locking ring. This is inserted into the opening mechanism and prevents accidental disconnection of the coupling. An opening aid is also included, which makes it easier to disconnect the coupling in tight systems.
Compatibility:
- G1/4" OT connections
- quick release coupling OT/OT (art. 17537)
- quick release coupling IT/IT (art. 17569)
- quick release coupling TPV (art. 17469)

Alphacool's Eiszapfen is the high-end version of the already proven connectors and meets all the requirements placed on a connector with its high-flow, shape, processing and colour.
Compatibility
This adapter has a rotatable ¼” external screw thread on one side and a ¼” internal thread on the other side. This 45° angle connector is mostly useful in cases where ¼” threads are too close to one another and larger hose connections do not fit next to each other.
Design
With brilliant chrome, deep matt black and decent matt white, three colour variants are available that fit perfectly into any system. Thanks to special processes, the coatings are firmly bonded to the substrate. This ensures a high longevity of the colours and prevents the coating from flaking off. The connector now also has the Alphacool logo, which makes it unique in addition to its special shape!
