## Long description

EK-Quantum Torque HDC 12 Silver 1/4" hex end fitting 6-pack contains six precision-machined end fittings intended for use with torque wrenches in liquid-cooling builds. Each fitting accepts a 1/4" imperial hex key and provides a consistent torque interface for repeatable installation of 12 mm hard-tube compression fittings used with acrylic or PETG tubing. Finished in silver and manufactured in Slovenia, these attachments are supplied in protective black foam packaging to prevent transport damage and are compatible with EK-Quantum series components and interchangeable aesthetic rings (sold separately).
Advantages
These torque wrench end fittings deliver a consistent and reliable contact point for tightening compression fittings, reducing the risk of under- or over-tightening compared with improvised tools. The 1/4" hex acceptance allows use with standard imperial torque wrench bits and adapters, ensuring repeatable torque application. Grooved outer surfaces facilitate easier hand-starting and handling, while the design preserves the factory appearance by avoiding visible branding. Protective foam packaging helps ensure the fittings arrive undamaged.
Suitable for
 Installing and torquing 12 mm hard-tube compression fittings (acrylic, PETG)
 Controlled tightening of adapters and compression rings in custom water-cooling loops
 Repeatable assembly tasks that require consistent torque application
 PC builders and system integrators working with EK-Quantum series components

How to use
Select the appropriate 1/4" hex bit or adapter for your torque wrench and fit it into the end fitting. Hand-start the compression fitting components to ensure proper thread alignment, then engage the torque wrench with the fitted end piece. Apply torque according to the fitting manufacturer's recommended values for 12 mm hard-tube compression fittings, turning the wrench until the specified torque is achieved. After torqueing, verify the compression ring and aesthetic ring (if installed) are seated correctly and inspect for proper tube retention.
Usage recommendations
Use a calibrated torque wrench and follow the recommended torque specifications for hard-tube compression fittings to avoid damage. Install aesthetic rings before final torque if using colored rings sold separately. Hand-start threads and check alignment before applying torque. Store unused fittings in their protective foam to prevent scratches or dents.
