Product information

Description

Alphacool ES D-Plug is an adjustable drain plug designed for PC liquid-cooling systems. It provides a controllable drain and vent connection with G1/4 male to G1/4 male threading and covers a diameter range of 41–69 mm. Finished in Deep Black, the D-Plug enables maintenance tasks such as fluid changes and air bleeding at radiators, reservoirs or dedicated loop points without full disassembly.

Advantages

The adjustable design accommodates a wide range of installation diameters, reducing the need for adapters. G1/4 threading on both sides ensures compatibility with common fittings and extensions used in water-cooling loops. The Deep Black finish offers corrosion resistance and a discreet appearance inside a PC chassis. The D-Plug gives precise control over draining and venting, improving safety and cleanliness during maintenance operations.

Suitable for

Draining and venting radiators
Maintenance and fluid replacement of reservoirs
Adding a temporary drain point to a cooling loop
Air bleeding during system filling and servicing

Key specifications

Thread type: G1/4 male to G1/4 male
Adjustable diameter range: 41–69 mm
Finish: Deep Black
Function: Controllable drain and vent
Application: PC liquid-cooling systems (radiators, reservoirs, loop points)

How to use

Install the D-Plug by inserting it into an appropriate opening on a radiator, reservoir or designated loop port and tighten until the adjustable collar seals against the mounting surface. Attach a hose or fitting to the G1/4 male thread as required for draining or venting. Operate the plug to control fluid flow when performing fluid changes or air removal; close the plug securely after use to restore a leak-free loop. Follow standard safety and leak-testing procedures when working on liquid-cooling systems.

Usage recommendations

Before first use, verify thread compatibility with existing fittings and perform a controlled leak test after installation. Use appropriate tubing or a collection container when draining coolant, and avoid opening the plug while the system is pressurized or hot.
