Alphacool ES Quick Release BLH1A PushIn Female with Barbed Fitting for 12.7/7.6mm (14638)

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.
