## Summary description

EK Water Blocks EK-Quantum Torque HDC is a torque wrench end fitting in black finish with a 1/4" (imperial) hex key size. Designed for precise tightening of fittings and components in liquid-cooling builds, it provides secure engagement with hex fasteners and helps maintain correct torque settings to prevent over- or under-tightening.

## Long description

EK-Quantum Torque HTC 12 fittings are minimalistic 12mm hard-tube compression fittings designed for use with solid tubing such as acrylic and PETG. They feature a low-profile, unbranded appearance and can be paired with interchangeable aesthetic color rings. The fittings are compatible with EK-Quantum series components and provide a secure mechanical connection for rigid tubing in liquid-cooling loops.
Advantages
The locking ring compresses a rubber gasket to prevent the solid tube from being pulled out, while external grooves allow easier hand tightening. The compression ring includes EK-Quantum signature cutouts that reveal an installed colored aesthetic ring. Colored rings are screwed onto the fitting before the compression locking ring and are available separately.
Suitable for
Rigid liquid-cooling loops using 12mm outer-diameter acrylic or PETG tubing
Custom PC water-cooling builds that require low-profile, minimal fittings
Assemblies that will use interchangeable aesthetic color rings for visual customization
Key specifications
Type: 12mm hard-tube compression fitting (for solid tubing)
Compatibility: EK-Quantum series components
Locking mechanism: Compression locking ring with rubber gasket seal
Aesthetic rings: Sold separately; installed before compression ring
Finish/Style: Minimalistic, no visible branding
How to use
Position the 12mm solid tube into the fitting until it contacts the internal stop. Screw the colored aesthetic ring onto the fitting if desired, then slide and tighten the compression locking ring by hand until the rubber gasket is compressed and the tube is held firmly. Use the external grooves to improve grip during hand tightening. Do not overtighten; follow tube manufacturer guidance for insertion depth and handling.
Usage recommendations
Use only with rigid acrylic or PETG tubing of the correct 12mm outer diameter. Verify compatibility with your EK-Quantum components and purchase aesthetic rings separately if color customization is required. Avoid excessive force when tightening to prevent damage to the tube or fitting.
