Plug EKWB EK-Quantum Torque Plug — Brass, Black/Silver, Ø 23 mm, Height 5.5 mm

EK-Quantum Torque Plug by EKWB is a brass G1/4" plug finished in black and silver, designed to close unused ports in custom PC liquid-cooling systems. With a diameter of 23 mm and a height of 5.5 mm, this plug provides a durable, sealed termination for radiators, water blocks or fittings. The part is CNC machined from brass, sealed with a quality O-ring and includes an attachable badge for a finished appearance. EK recommends initial hand tightening or using the EK-Loop Multi Allen Key, and attaching the enclosed badge once the plug is set in its final position.

Advantages

The brass construction and CNC machining ensure dimensional accuracy and long-term durability while the satin black and silver finish resists corrosion and complements a variety of build styles. The integrated O-ring provides a reliable seal to prevent leaks in G1/4" or similarly threaded ports. The included badge allows a neat visual finish and the Torque family’s precision manufacturing contributes to consistent fit and compatibility across liquid-cooling components.

Suitable for

• Sealing unused G1/4" or similar threaded ports on radiators
• Closing spare ports on CPU or GPU water blocks
• Finishing open fittings or distribution plates in custom loops
• Replacement or visual upgrade for existing plug covers

Key specifications

• Material: CNC machined brass
• Finish: Satin black and silver
• Thread type: Designed for G1/4" or similar threads
• Diameter: 23 mm
• Height: 5.5 mm
• Sealing: O-ring included for leak prevention
• Accessory: Removable badge included

How to use

Start by screwing the plug into the unused G1/4" or similarly threaded port by hand until it seats. If additional torque is required, use the EK-Loop Multi Allen Key to tighten gently to the desired snugness—avoid over-tightening to protect threads and the O-ring. Once the plug is in its final position, attach the enclosed EK-Badge for a finished look. Periodically inspect the O-ring and seating during maintenance to ensure a continued leak-free connection.

Recommendations

Hand-tighten first and use only light tool torque if necessary; replace the O-ring if signs of wear or deformation appear. Ensure compatibility with the port thread before installation and verify sealing during the first leak test after mounting.
