Radiator mount Alphacool ES D-Plug Black Brass 2 cm 35 g

The Alphacool ES D-Plug is a brass connector with two G1/4" male threads designed to join water-cooling components such as GPU and CPU coolers or radiators within a liquid circuit. It features a black finish, variable length up to 15 mm extension, and is compact for use in tight spaces.

Advantages

The ES D-Plug is a push-fit connector rather than a threaded adapter, relying on two closely fitting O-rings on the male component to provide sealing and stability. Laboratory testing shows reliable performance up to 1.5 bar. Its adjustable length and included replacement O-rings in different colors allow for compensation of alignment tolerances and simplify installation or quick replacement.

Suitable for

• Connecting GPU and CPU water blocks
• Joining radiators and other cooling components in a loop
• Installation in confined or cramped case locations

Key specifications

• Material: brass with black finish
• Thread type: G1/4" male (two threads)
• Variable length: up to 15 mm extension
• Pressure rating (tested): up to 1.5 bar
• Weight: approx. 35 g

How to use

Push the male component into the female counterpart until both O-rings are fully recessed to ensure a secure, leak-free connection. If additional length is required, pull the connector apart to extend it by up to 15 mm, then insert again. Replace O-rings if necessary using the included spare rings to maintain sealing performance.

Recommendations

Ensure both O-rings on the male component are fully seated inside the female component to achieve the required stability and tightness. Check O-rings periodically and replace if worn. Avoid exceeding the tested pressure of 1.5 bar.
