Plug EKWB Quantum Torque Plug — Nickel stainless steel, Ø 2.3 cm

EKWB Quantum Torque Plug — Nickel stainless steel, Ø 2.3 cm is a compact metal plug designed for closing unused G1/4" ports in custom PC liquid-cooling loops. Machined from nickel-plated brass with a stainless-steel appearance, the plug provides a durable, corrosion-resistant seal and is finished with a quality O-ring to prevent leaks. The plug includes an EK-Badge for final visual customization and pairs with standard liquid-cooling radiators, blocks and fittings that use G1/4" threading.

Advantages

The plug combines CNC-machined nickel-plated construction and a precision O-ring seal to deliver reliable long-term protection against leaks and corrosion. Its compact Ø 2.3 cm profile and robust finish ensure consistent mechanical fit and an industrial aesthetic that matches other Quantum Torque components. The included badge allows a clean final appearance, and the plug is compatible with common tools such as the EK-Loop Multi Allen Key for controlled tightening.

Suitable for

• Closing unused G1/4" ports on radiators, water blocks and fittings
• Custom PC water‑cooling builds requiring corrosion-resistant port caps
• Maintenance or modification work where temporary or permanent port sealing is needed

Key specifications

• Material: nickel-plated brass (stainless-steel appearance)
• Seal: quality O-ring for leak prevention
• Diameter: Ø 2.3 cm
• Thread standard: G1/4" compatible
• Finish: CNC-machined surface with nickel plating

How to use

Start by hand-threading the plug into the unused G1/4" port to ensure proper engagement and avoid cross-threading. Tighten the plug until seated, then use the EK-Loop Multi Allen Key or an appropriate tool to apply the final torque if necessary; EKWB recommends initial hand tightening followed by tool-assisted final positioning. After the plug is secure, attach the enclosed EK-Badge to complete the appearance. Verify seal integrity by checking for leaks after filling and pressurizing the loop.

Recommendations

Do not overtighten the plug to avoid damaging threads or the O-ring. During installation or maintenance, inspect the O-ring for wear and replace if compromised. Use hand tightening first and a torque-limiting tool only for final adjustment; periodically check sealed ports as part of routine system maintenance.
