Fitting EK Water Blocks Brass Gold 3.75mm Height 2.3cm Diameter

EK-Quantum Torque Surface Port Adapter - Gold is a compact male+female G1/4" threaded adapter designed for EK-Quantum Surface radiators and EK Multiport radiators. It adds an extra functional port to the radiator body that can accept a thermal probe, drain valve, fill port, or be used to configure parallel flow. The adapter is CNC machined from brass, nickel-plated and finished with genuine gold plating, and sealed with EPDM O-rings for reliable leak protection.

Advantages

The adapter provides a small-diameter, low-profile connection that preserves radiator aesthetics while expanding functionality. High-quality brass construction with nickel and gold plating offers corrosion resistance and long service life. EPDM O-rings ensure a secure seal, and the Torque design fits the EK-Quantum family for modular compatibility.

Suitable for

• Adding a G1/4" thermal probe port to EK-Quantum Surface radiators
• Installing a drain valve or fill port on the radiator
• Reconfiguring radiator flow to a parallel layout
• Any custom liquid cooling loop requiring a small-diameter radiator port

How to use

Install the adapter into a compatible G1/4" port on an EK-Quantum Surface or Multiport radiator by hand-tightening and completing the final turn with an appropriate tool if required, taking care not to overtighten. Fit the desired accessory—thermal probe, drain valve, or fill port—into the exposed thread and ensure EPDM O-rings are properly seated to maintain a leak-free connection. Verify orientation and clearance inside the case before powering the system.

Recommendations

Use this adapter only with EK-Quantum Surface and Multiport radiators or other components that accept G1/4" fittings. Check O-rings periodically for wear and replace if damaged. Avoid excessive torque during installation to prevent thread or plating damage.
