Product information

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

Key specifications

  • Brand: Alphacool
  • Model / MPN: 17590
  • Material: Brass
  • Finish: Matte black
  • Threads: G1/4" female to G1/4" male
  • Angle: 45°
  • Dimensions: 20 mm × 21 mm × 21 mm
  • EAN: 4250197175906

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.
