The Alphacool ES quick-release couplings of the Industry Version have been specially developed for professional use in data centers, workstations, and industrial applications. They provide maximum reliability in continuous operation and allow cooling circuits to be connected or disconnected quickly, safely, and with minimal fluid loss. Thanks to their robust design and the PushIn system, installations can be easily expanded or maintained. All couplings in this series are mutually compatible and also fit the already available sets. For a complete connection, one male and one female coupling are always required. A key advantage of the Industry Version is its low weight. Made of high-quality nylon, the couplings are non-conductive and prevent short circuits – a crucial factor in modern server environments with high component density. The ultra-light material also makes handling and installation significantly easier. Unlike conventional quick-release couplings, which often create high flow resistance due to narrow water passages, this series has been developed for optimized flow. This keeps resistance to a minimum while ensuring maximum cooling performance. For maximum safety, a double-seal design is used as usual to ensure absolute leak-tightness. In addition, a locking clip prevents the coupling from accidentally opening. The bulkhead fitting with G1/4 inner thread and male PushIn connection is designed for installation through case or panel walls. This allows for clean and stable routing of tubing. Note When disconnecting the coupling, a few drops may escape.
