Water block Alphacool 17584 Brass Chrome 23.5mm x 31mm x 18.5mm

The Alphacool Low Profile ES L-connector with G1/4" male and G1/4" female threads enables secure connection of water-cooling components such as GPU and CPU coolers, reservoirs or radiators inside very tight server cases. The connector is part of Alphacool's ENTERPRISE SOLUTIONS line and is designed for low-profile installations where space is limited.

Advantages

The Low Profile ES L-connector allows 360° rotation via a recessed, freely rotatable plug with a screwdriver slot on the threaded end, so the body of the connector itself does not need to be turned during installation. This design simplifies assembly and later adjustments in cramped housings. The connector is available in brilliant chrome or matt black with a durable surface treatment that reduces the risk of chipping or peeling. Each unit includes replacement O-rings in three colours and features the Alphacool logo for clear identification.

Suitable for

• Connecting GPU and CPU water blocks in compact server or workstation cases
• Linking reservoirs and radiators in confined water-cooling loops
• Upgrades or repairs where low-profile fittings are required

Key specifications

• Thread type: 1 x G1/4" male – 1 x G1/4" female
• Rotation: 360° via recessed rotatable plug with screwdriver slot
• Finish options: brilliant chrome or matt black with bonded coating
• Includes: replacement O-rings in three colours

How to use

Install the Low Profile ES L-connector by screwing the threaded ends into the corresponding G1/4" ports on your water-cooling components. Use a screwdriver or Alphacool’s plug-in tool in the recessed slot to rotate and position the plug independently of the connector body, allowing final alignment without turning the fitting itself. Tighten to appropriate torque for your system and verify seals using the supplied O-rings.

Recommendations

For reliable operation in server environments, select the chrome or matt black finish to match system aesthetics and ensure the O-rings are correctly seated before pressurising the loop. Periodically inspect fittings and O-rings during maintenance to maintain leak-free connections.
