EK-AF ALU Angled 90° G1/4 is a revolvable angled (90°) adapter fitting with G1/4″ threads. Adding adapters like these to your liquid cooled build makes tube routing much easier and more elegant at the same time. These rotary adapter fittings can rotate – they have the base that gets screwed into G1/4“ port and the top of the fitting can rotate 360°, full circle.
