Liitin Alphacool 90° G1/4 AG – 13 mm AD Hardtube kierrettävä – Alphacool 17620

Alphacool 90° G1/4 AG to 13mm AD Hardtube Rotatable fitting (model 17620) provides a compact right-angle connection for custom PC liquid-cooling loops. The fitting accepts 13 mm outer-diameter hard tubing and uses a G1/4 male thread for secure attachment to standard water-cooling components. Its rotatable design allows alignment of the hardtube orientation after tightening, simplifying installation and reducing mechanical stress on bends and joints.

Advantages

The rotatable 90° design offers flexible orientation without loosening the sealed connection, enabling fine alignment in confined spaces. Precision machining ensures a consistent seal and dimensional accuracy for reliable connections with other G1/4-compatible components. The fitting’s form factor minimizes required clearance at corners and allows neater tubing runs in professional and enthusiast builds.

Suitable for

• Custom PC liquid-cooling loops using 13 mm outer-diameter hard tubing
• Right-angle connections where space is limited or tight routing is required
• Builds requiring post-installation rotational adjustment of tubing orientation
• Professional and enthusiast systems aiming for precise, compact tubing layouts

Key specifications

• Connection type: G1/4 male thread to hardtube adapter
• Hardtube outer diameter compatibility: 13 mm
• Angle: 90° right-angle
• Rotatable joint for post-tightening orientation adjustment
• Material: metal construction suitable for liquid-cooling applications

How to use

Prepare the hard tubing by cutting and deburring to ensure square, clean ends. Insert the 13 mm hardtube into the adapter and tighten according to the manufacturer's recommended torque for fittings using G1/4 threads. After securing the threaded connection to the mating component, rotate the outer section of the fitting to the desired orientation to align the tubing path without compromising the sealed thread. Check for proper sealing and avoid overtightening that could damage threads or deform tubing.

Recommendations

Use with compatible G1/4 threaded components and 13 mm outer-diameter hard tubing. Verify material compatibility with your coolant and ensure all cuts are deburred and clean before assembly. Perform a leak test at low pressure after installation and periodically inspect seals during system maintenance.
