## Long description

Set of six OEM EK-Quantum Torque HDC 12 Black 1/4" hex end fittings for torque wrenches, designed to enable controlled tightening of EK-Quantum HDC 12 hard-tube compression fittings. These end fittings interface with 1/4" (imperial) hex torque wrench drives and are intended for precision assembly and maintenance of water-cooling systems and other applications where accurate torque control is required. Manufactured in Slovenia and packaged in protective foam to reduce the risk of damage during transport.
Advantages
These torque wrench end fittings provide a precise mechanical interface between a 1/4" hex torque wrench and EK-Quantum HDC 12 compression fittings. The design allows controlled application of torque to compression fittings used with solid tubing (Acrylic, PETG), improving repeatability and reducing the risk of overtightening. Grooved outer surfaces support easier hand-driven positioning, while the compact OEM design omits visible branding for a subtle appearance. A set of six ensures availability of spare fittings or simultaneous use across multiple assemblies.
Suitable for
Tightening EK-Quantum HDC 12 hard-tube compression fittings with a 1/4" hex torque wrench
Assembly and maintenance of custom water-cooling loops using acrylic or PETG tubing
Situations requiring repeatable torque application across multiple fittings
Key specifications

How to use
Attach the 1/4" hex end fitting to the torque wrench drive, then engage the fitting with the compression nut of an EK-Quantum HDC 12 fitting. Set the torque wrench to the recommended torque value for your compression fitting and tubing, then apply torque until the wrench indicates the set value. Use the grooved outer surfaces for hand alignment before using the torque wrench. After tightening, verify the connection for correct compression and alignment of the tubing.
Usage recommendations
Use the end fittings only with torque wrenches and EK-Quantum HDC 12 compression fittings. Always follow the torque values specified by the fitting or system manufacturer to avoid damage to hard tubing or fittings. Store spare end fittings in the original foam-packed box to prevent deformation and ensure long-term usability.
