Radiator mount Alphacool ES D-Plug Chrome Brass 2 cm 44 g

The Alphacool ES D-Plug Chrome Brass 2 cm is a compact connector for water-cooling systems, designed to link components such as radiators, GPU coolers and CPU blocks using two G1/4" male threads. Manufactured from brass with a chrome finish, this D-Plug is available in multiple lengths and includes spare O-rings to ensure a reliable seal.

Advantages

The ES D-Plug is a push-fit connector rather than a screw-in adapter, relying on two closely fitting O-rings on the male section to provide sealing and stability. Laboratory tests confirm stability up to 1.5 bar. The connector offers a variable length that can extend up to 15 mm by pulling the parts apart, allowing compensation for alignment tolerances and preventing hose twisting during assembly. Replacement O-rings in different colours are supplied.

Suitable for

• Connecting radiators to CPU or GPU water blocks
• Linking components in tight or compact water-cooling layouts
• Quick replacement or temporary disconnection of loop parts

How to use

Ensure both mating G1/4" female ports are clean and free of debris. Push the male D-Plug into the female fitting until both O-rings are fully recessed into the female component to achieve proper sealing. If additional clearance is required, pull the connector to extend it up to 15 mm and align components before final insertion. Replace O-rings if damaged or leaking.

Recommendations

To maintain a secure and leak-free connection, always verify that both O-rings on the male section are fully seated inside the female fitting. Inspect O-rings periodically and replace with the supplied spare rings when wear or deformation is visible.
