With its precisely machined barbed fitting and solid brass construction, this connector ensures a secure and leak-proof connection for 12.7 / 7.6 mm 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. Thanks to the 90° rotatable design, tubing can be routed with exceptional flexibility.

The fitting simplifies clean loop layout, reduces mechanical stress on the tubing, and enables space-saving installations — ideal for compact cases or densely packed rack systems. ES Series – developed for professionalsEach 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.
