## Long description

EK Water Blocks EK-Quantum Torque 6-Pack HDC 16 Black 1/4" hex is a set of six torque wrench end fittings made for use with 16 mm hard-tube compression fittings in custom PC liquid-cooling loops. Each end fitting features a 1/4" imperial hex interface for attachment to compatible torque wrenches and is finished in black. The pack is intended to assist assembly and maintenance by providing standardized wrench interfaces that work with EK-Quantum HDC 16 compression fittings and solid tubing such as acrylic and PETG. The fittings are manufactured in Slovenia and are shipped cushioned in black foam to prevent transport damage.
Advantages
These EK-Quantum Torque end fittings provide a consistent hex interface that helps achieve repeatable and secure tightening with compatible torque wrenches. The black finish offers a discreet look that integrates with EK-Quantum series components. The design preserves the mechanical features of HDC 16 fittings: a locking ring that compresses the internal rubber gasket to prevent solid tube slippage, external grooves for improved hand tightening, and cutouts that reveal the optional aesthetic color ring when installed. The pack of six ensures multiple connection points can be fitted or serviced at once.
Suitable for
 Assembly of PC liquid-cooling loops using EK-Quantum HDC 16 hard-tube compression fittings
 Maintenance and re-tightening of 16 mm solid tubing connections (acrylic, PETG)
 Work requiring a standardized 1/4" hex interface for torque wrenches on water-cooling fittings
Key specifications
 Quantity: 6 pieces per pack
 Compatible tube type: 16 mm hard-tube (solid tubing such as acrylic and PETG)
 Interface: 1/4" imperial hex for torque wrenches
 Finish: black
 Designed use: hard-tube compression fittings (HDC 16)
 Origin: Slovenia
How to use
Attach each Torque end fitting to a compatible torque wrench via the 1/4" hex interface. Fit the end fitting onto the external locking ring of an EK-Quantum HDC 16 compression fitting and apply torque according to the torque wrench and fitting manufacturer's recommended values. The locking ring compresses the internal gasket to secure the solid tube; use the external grooves for initial hand tightening before applying the torque wrench for final adjustment. When aesthetic color rings are used, mount them onto the fitting before installing the compression locking ring as designed.
Usage recommendations
Use a torque wrench calibrated for the recommended torque values for EK HDC fittings to avoid over- or under-tightening. Inspect the rubber gasket and tube ends for damage before assembly, and follow EK Water Blocks’ guidelines for hard-tube installation and maintenance. Store unused fittings in their original foam-cushioned packaging to prevent scratches and deformation.
