The Alphacool ES G1/4 barbed fitting (short) for 12.7/7.6mm diameters is part of Alphacool's professional ES series and sets new standards in design, functionality, and reliability for water cooling systems in servers, workstations, and industrial applications. With its precisely manufactured nozzle and solid brass housing, this fitting ensures a secure and leak-proof connection with 12.7/7.6mm hoses. The inner diameter is optimized for minimal flow resistance, thus supporting effective coolant flow – even in complex system configurations. Nozzle fittings offer a compact and uncomplicated alternative to compression fittings. They reveal more of the hose used and save space – particularly advantageous in confined installation situations or special system setups. ES series – developed for professionals. Every component of the Alphacool ES series has been designed to meet professional requirements for reliability and performance. Whether in a high-performance workstation or in industrial cooling systems, these fittings offer consistently high performance and robust quality. Note: For greater safety and optimal hose retention, we recommend using the ES wire clamp (item no. 10282) when using this fitting. This ensures a tighter hose fit—especially important when pressure increases or temperature fluctuations occur.
