## Long description

Set of six EK Water Blocks EK-Quantum Torque HDC 12 black torque-wrench end fittings for 1/4" hex keys. These replacement ends are manufactured in Slovenia and are made to engage securely with 1/4" (imperial) hex driver tools for installing or removing HDC 12 hard-tube compression fittings used in PC liquid-cooling loops. The pack contains six identical end fittings supplied in protective black-foam packaging to avoid transport damage.
Advantages
The fittings provide precise engagement with 1/4" hex torque wrenches to help ensure consistent tightening and controlled torque application when working with HDC 12 compression fittings. Their black finish is non-intrusive and there is no visible branding on the parts. The design accommodates the EK-Quantum aesthetic rings (sold separately) and the compression ring incorporates grooves for easier hand tightening and cutouts that allow the color ring to be visible once assembled. A rubber gasket under the locking ring is compressed by the compression ring to prevent the solid tube from being pulled out.
Suitable for
Installing or removing HDC 12 hard-tube compression fittings in PC liquid-cooling loops
Precision tightening tasks where a 1/4" hex torque wrench is used
Maintenance and replacement of fittings on custom water-cooling assemblies
Key specifications
Quantity: 6 end fittings
Compatibility: HDC 12 hard-tube compression fittings
Drive type: 1/4" (imperial) hex engagement
Finish: black
Origin: manufactured in Slovenia
Packaging: protected in black foam within a box
How to use
Fit the appropriate EK-Quantum Torque HDC 12 end onto your 1/4" hex torque wrench and engage the end with the matching hex on the HDC 12 compression fitting. Apply torque according to your torque-wrench settings and the tubing/fitting manufacturer recommendations to achieve secure compression without over-tightening. If aesthetic rings are to be used, thread the colored ring onto the fitting before installing the compression locking ring so the ring is visible through the compression cutouts. Inspect the rubber gasket under the locking ring to ensure it is correctly seated before final tightening.
Usage recommendations
The fittings are intended for use with solid tubing systems such as acrylic or PETG and with HDC 12 compression fittings; follow component-specific torque guidelines and perform a leak test after installation. Store unused fittings in their protective foam to prevent scratches and contamination.
