## Summary description

The Alphacool 17590 water blocks adapter is designed for efficient cooling systems. Made of durable brass, it features a sleek black finish. With dimensions of 20mm width, 21mm depth, and 21mm height, it is compact yet effective. This adapter is essential for enhancing the performance of your computer cooling setup.

## Long description

The Alphacool 17590 water blocks adapter is a 45° angled brass fitting with G1/4" female and G1/4" male threads, finished in matte black. Its compact dimensions (20 mm × 21 mm × 21 mm) make it suitable for tight spaces in custom water-cooling loops. The outer coating is applied with a special process to resist chipping and peeling, and each connector bears the Alphacool logo and the series' distinctive shape. Three coloured O-rings are included; under UV light these O-rings glow in their respective colours.
Advantages
The adapter provides a high-flow, precisely machined connection between components while saving space thanks to its 45° angle. Durable brass construction combined with a firmly bonded matte black coating improves longevity and maintains appearance under operational conditions. Supplied coloured O-rings offer visual differentiation and UV-reactive options for illuminated setups.
Suitable for
Custom PC water-cooling loops with limited installation space
Connecting water blocks, radiators, pumps or tubing at a 45° angle
Builds requiring G1/4" thread compatibility

How to use
Install the adapter by threading the G1/4" male or female ends into the corresponding G1/4" ports on water blocks, radiators, pumps or other fittings. Ensure threads are aligned and hand-tighten before final tightening with an appropriate tool to avoid cross-threading. Fit one of the supplied O-rings to achieve a secure seal and, if used, select a UV-reactive O-ring for illuminated setups. Check for leaks after pressurising the loop and re-tighten if necessary.
Usage recommendations
Use compatible G1/4" fittings and avoid excessive torque when tightening to protect the brass threads and the coating. Perform a leak test before running the system under full load. Store spare O-rings separately to preserve their UV properties.
