## Long description

EK-Quantum Torque Micro Plug - Black is a compact G1/4" brass plug designed to close unused ports in PC liquid cooling systems. CNC-machined and finished in satin black, the plug features a rubber O-ring seal and a low-profile form factor (Ø 16.5 mm, H 7 mm) for tight spaces and small-form-factor builds. It is part of EK's Torque family of fittings, which includes a range of adapters, extenders, splitters and plugs.
Advantages
The micro plug provides a secure, leak-resistant seal for unused G1/4" ports while occupying minimal space near other fittings. Its CNC-machined brass construction with satin black coating offers durability and a consistent appearance. The integrated rubber O-ring ensures a reliable seal, and the compact dimensions make it suitable for close-clearance installations where standard plugs would interfere with neighbouring components.
Suitable for
Sealing unused G1/4" ports on water blocks, radiators and distribution plates
Small-form-factor (SFF) PC builds with limited clearance
Close-clearance areas where standard plugs are too large or visible

How to use
Hand-start the EK-Quantum Torque Micro Plug into the unused G1/4" port and tighten by hand until the rubber O-ring compresses and the plug sits flush. EK recommends hand-tightening only to avoid over-torquing; do not use tools unless explicitly required. Inspect the O-ring for damage before installation and replace it if necessary. For maintenance, remove the plug by unscrewing it by hand and clean the threads and O-ring area to prevent buildup.
Usage recommendations
Use these micro plugs in tight or visible areas to achieve a cleaner look and secure sealing. Avoid overtightening with tools; periodic inspection of the O-ring is advised to maintain leak-free operation.
