Alphacool ES G1/4 barbed fitting for 12.7/7.6mm

The Alphacool ES G1/4 barbed fitting for 12.7/7.6mm 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 machined barbed fitting and solid brass construction, this connector ensures a secure and leak-proof connection for 12.7/7.6mm tubing. The internal diameter is optimized for minimal flow resistance, supporting effective coolant circulation even in complex system configurations.

Hose barb fittings offer a compact and straightforward alternative to compression fittings, highlighting more of the tubing and saving space — especially useful in tight installations or specialized setups. Despite their minimal form factor, they provide secure hose grip and high flow capacity.

ES Series – developed for professionals
Each component in Alphacool’s ES line is engineered for professional-grade reliability and performance. Whether in a high-performance workstation or industrial cooling setup, these fittings deliver consistent performance and robust build quality.

Note:
For increased safety and optimal tube retention, we recommend using the ES wire tensioning clamp (Art. No. 10282) in combination with this fitting. It provides a more secure grip on the tubing – especially important under elevated pressure or temperature fluctuations.
