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° 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.
