The Alphacool ES G1/4 90 degree rotatable Fitting with Barbed Fitting for TPV Tubes 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. Thanks to the 90 degree 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.
