## Long description

EK Water Blocks EK-Quantum Torque HDC 16 — 9 mm hex, black is a torque wrench end fitting designed to provide a precise 9 mm metric hex interface for use with compatible torque wrenches and HDC 16 fittings. It is intended for liquid-cooling assemblies and PC hardware where reliable torque transfer and an exact hex drive are required. The fitting matches EK-Quantum HDC 16 hard-tube compression fittings and maintains a minimal, brand-free visual profile while allowing optional aesthetic customization via separately sold colored rings.
Advantages
This torque wrench end fitting offers a direct 9 mm hex connection that enables accurate tightening and loosening of fasteners without relying on adapters. Its black finish and compact design preserve the minimal look of EK-Quantum HDC 16 fittings and the outer grooves on the locking ring provide improved grip for hand tightening. The component is compatible with hard-tube systems using 16 mm HDC fittings and works with the same locking-ring mechanism that secures solid tubing by compressing the rubber gasket beneath the ring.
Suitable for
 Assembly and disassembly of liquid-cooling fittings with 9 mm hex fasteners
 Maintenance and periodic retorquing of PC water-cooling loops
 Precision work on EK-Quantum HDC 16 hard-tube compression fittings
 Situations requiring a compact, non-branded hex interface for torque wrenches
Key specifications
 Hex interface: 9 mm metric
 Color / finish: black
 Compatibility: designed for use with EK-Quantum HDC 16 hard-tube compression fittings
 Application: torque wrench end fitting for tightening/loosening fasteners in liquid-cooling assemblies
 Material: metal construction suitable for torque transfer (color and finish as specified)
How to use
Attach the torque wrench end fitting to a compatible torque wrench square or adapter as specified by your torque wrench manufacturer so the 9 mm hex engages the fastener head. Use the torque wrench to apply the required torque value when tightening or loosening fasteners on EK-Quantum HDC 16 fittings, taking care to follow EK’s recommended torque specifications for compression fittings and tubing. For hand adjustments, the external grooves on the locking ring allow improved grip during manual tightening before final torque is applied with the wrench.
Usage recommendations
Use calibrated torque wrenches and follow manufacturer torque values for compression fittings to avoid over-tightening. Pair the end fitting with EK-Quantum HDC 16 components and, if desired, install separately sold aesthetic rings onto the fitting before fitting the compression locking ring. Inspect the rubber gasket and compression surfaces during maintenance and replace any damaged seals to maintain leak-free performance.
