The Alphacool ES Quick Release BLH1A PushIn connector with barbed fitting for 12.7/7.6 mm tubing is specially developed for use in server and workstation systems. It combines high-precision manufacturing with excellent water flow and a secure click-lock system to ensure safe and efficient handling. Unlike many conventional quick couplings, this model has been fundamentally optimized to minimize flow resistance. The internal geometry and tight production tolerances ensure a consistent and efficient coolant flow. Alphacool's ES quick-release system allows for fast and uncomplicated integration into complex cooling circuits. The outer ring is simply pulled back to separate the connection ? the integrated seal automatically closes to prevent coolant leakage. Reconnection is just as straightforward: push the two parts together until a distinct click confirms a secure lock. This version features a PushIn connection with an integrated barbed fitting, designed specifically for 12.7 mm outer diameter and 7.6 mm inner diameter tubing. This ensures a tight and reliable fit for a wide range of industrial and professional applications. Important note: This product includes only one half of the quick-release connector ? either the male or female version. A complete connection requires the matching counterpart. To prevent damage to the O-ring, the quick coupling should not be opened or closed when dry.
