Fitting EKWB Quantum Torque Plug — 23×23×5.5 mm fitting for liquid cooling

EKWB Quantum Torque Plug — 23×23×5.5 mm fitting for liquid cooling is a compact G1/4" plug designed for custom PC water cooling systems. It functions as a closure or connection point within liquid cooling loops, allowing users to seal unused ports, redirect coolant paths, and maintain leak-free joins between components. The part is suitable for standard fittings and tubing used in CPU and GPU water-cooling setups and is offered in a black finish for discreet integration into system layouts.

Advantages

The plug provides a secure, low-profile seal for unused G1/4" ports and integrates with common liquid-cooling fittings. Its compact 23×23×5.5 mm dimensions minimise protrusion inside tight builds while preserving coolant flow integrity. The torque-style design offers straightforward installation and removal without specialised tools when tightened by hand as recommended, reducing the risk of cross-threading and over-torquing.

Suitable for

• Sealing unused ports on water blocks, radiators, and reservoirs
• Redirecting coolant runs in custom loops
• Temporary closures during system maintenance or leak testing
• Tidy cable- and tube-routing in compact PC cases

Key specifications

• Type: G1/4" torque plug compatible with standard liquid-cooling fittings
• Dimensions: 23 × 23 × 5.5 mm (compact, low-profile design)
• Finish: black (discreet appearance for most builds)
• Material: metal construction suitable for liquid-cooling environments
• Compatibility: fits standard PC water-cooling ports and tubing interfaces

How to use

Confirm the target port uses a standard G1/4" thread and that the mating surface is clean and free of debris. Thread the plug into the unused port by hand and tighten until snug; EKWB recommends hand-tightening to avoid over-torquing. For maintenance or rearrangement, simply unscrew the plug by hand. If a watertight seal is required beyond the plug's design, use appropriate sealing tape or gasket materials compatible with coolant chemistry and system components.

Recommendations

Use the EKWB Quantum Torque Plug to close unused G1/4" ports during assembly and testing. Hand-tighten the plug as recommended to prevent damage to threads and avoid the need for tools. Regularly inspect sealed ports during maintenance to ensure there are no signs of leakage or corrosion.
