With Alphacool's patented retractable closure screws, the annoyance of protruding closure screws is finally a thing of the past. They are extremely practical not only in small cases where every millimeter counts but also leave a strong visual impression.

They securely seal unused connections using a new and patented sealing concept. The sealing rings are attached to the bottom of the closure screw and are pressed against a counter ring when screwed into compatible connections, ensuring a reliable seal.

Note: The retractable closure screws are compatible with our NexXxos radiators of the V.2 series as well as with the Alphacool GPX Aurora series.
