## Summary description

Angled 90° rotatable hardtube fitting from Alphacool, model 17621, with a G1/4 male thread and connection for 16 mm outside-diameter rigid tubing. Designed for liquid-cooling loops in PC systems, it provides a compact bend point and a rotatable joint for easier alignment during installation. Suited for custom water-cooling builds to help route tubing neatly and reduce stress on connections.

## Long description

Alphacool 90° Rotatable G1/4 Male to 16mm OD Hardtube Fitting is an angled hardtube connector designed for custom PC liquid-cooling loops. The fitting provides a 90-degree bend point while allowing rotational adjustment at the joint, enabling precise alignment of 16 mm outside-diameter rigid tubing. It is intended to create compact turns and reduce mechanical stress on tubing runs and thread connections in desktop water-cooling systems.
Advantages
The rotatable joint permits fine-tuning of tube orientation after the fitting is threaded into a component, which simplifies installation in confined spaces. The 90° angle offers a compact routing solution for hard tubing layouts and helps maintain consistent flow direction. Manufactured for compatibility with standard G1/4 threads and 16 mm OD rigid tubes, the fitting contributes to leak-resistant joins when installed with appropriate seals and properly seated tubes.
Suitable for
 Custom PC water-cooling loops using 16 mm OD hard tubing
 Tight or compact case layouts where space for tubing bends is limited
 Radiator, pump, water block, or reservoir connections requiring a 90° turn
 Builds that benefit from post-installation orientation adjustment
Key specifications
 Thread type: male G1/4 compatible
 Tube compatibility: rigid tubing with 16 mm outside diameter
 Angle: 90° bend with rotatable joint
 Connection style: hardtube compression-style interface for secure seating
 Application: internal PC liquid-cooling systems
How to use
Install the fitting by threading the male G1/4 portion into the component port until hand-tight, then use appropriate tools to secure to the manufacturer's recommended torque while avoiding over-tightening. Insert the 16 mm OD hard tube into the compression interface and ensure the tube is fully seated; if required, cut the tube squarely and deburr the edge before insertion. Rotate the fitting at the joint to achieve the desired tube orientation, then verify all connections and perform a pressure or leak test according to standard liquid-cooling procedures.
Usage recommendations
Use compatible seals or O-rings as specified by system components and verify tube dimensions before assembly. Avoid excessive force when tightening to prevent damage to threads or fittings. Perform an extended leak test before powering the system to ensure reliable operation.
