The Alphacool ES quick-release connector is optimized for use in server and workstation systems. It is characterized by precise manufacturing quality, excellent water flow and a secure click mechanism for sealing.
Maximum flow rate
Other quick couplings can negatively affect the flow of water. The quick coupling has therefore been fundamentally redesigned so that the water flow is hardly disrupted. Particular emphasis was placed on minimal processing tolerances.
Quick and easy
The ES quick connectors from Alphacool simplify the assembly of server and workstation systems. Thanks to the convenient handling, complex systems can be connected quickly and easily. To open the quick-release fastener, the outer ring is pulled back. The seal closes immediately and prevents coolant from escaping. To lock the quick-release fasteners, simply push them into each other. A clicking noise confirms secure locking.
A quick-release fastener always consists of two fittings. You always need the right counterpart to create a complete quick release fastener. With this product you only get 1 half of the quick-release fastener.
Note: To avoid damaging the O-ring, do not open or close the quick-release fastener when it is dry.
