Product information

Description

EK Water Blocks fitting in Satin Black is a brass adapter designed for liquid cooling systems in computers. Measuring approximately 23×21 mm, this compact, panel-mounted fitting features female G1/4" BSP threads on both ends and is supplied with a grip nut for securing it to a chassis panel. CNC-machined from brass and finished in black, the fitting provides a durable, corrosion-resistant connection point for routing coolant through internal or externally mounted components in custom loops.

Advantages

The brass construction and CNC machining ensure precise threading and mechanical strength while the satin black finish resists wear and complements modern chassis aesthetics. Female G1/4" BSP threads on both sides enable straightforward pass-through connections between separate compartments. The included grip nut simplifies panel mounting, offering a stable and leak-resistant junction when properly installed.

Suitable for

  • Small form factor (SFF) cases requiring external radiator or component placement
  • Panel pass-through connections between separate chassis compartments
  • Custom water-cooling loops that use G1/4" threaded components
  • Loop assembly, extension, or rework where a secure threaded adapter is needed

Key specifications

  • Material: brass (CNC-machined)
  • Finish: satin black
  • Thread type: female G1/4" BSP on both ends
  • Overall dimensions: approximately 23×21 mm
  • Mounting: panel-mounted using included grip nut

How to use

Install the fitting by inserting it into the chassis panel cutout and fastening the grip nut from the opposite side until the fitting is secure. Connect G1/4" threaded tubing adapters, compression fittings, or components to each side, ensuring thread seals or appropriate sealing tape are used where required to prevent leaks. Tighten threaded connections to a firm torque consistent with G1/4" water-cooling practice; avoid over-tightening to prevent damage to threads or sealing surfaces.

Usage recommendations

Before filling the loop, perform a pressure or leak test with distilled water or a test fluid to verify the integrity of the installed fitting. Use compatible tubing and fittings rated for your system's coolant and temperature range, and periodically inspect the mounted pass-through for signs of looseness or corrosion.
