## Long description

EK Water Blocks EK-Quantum Torque HDC 16 Silver 1/4" hex — 6-pack torque wrench end fittings for liquid cooling assembly. This set contains six HDC 16 silver fittings designed for 1/4" imperial hex interfaces, intended to attach to compatible torque wrenches and enable controlled, repeatable tightening of hard-tube compression fittings used in custom water cooling loops. Manufactured in Slovenia and shipped cushioned in black foam, the pack supports maintenance and assembly tasks by providing multiple interchangeable end fittings for a single torque wrench.
Advantages
The six-piece pack allows technicians and builders to keep spare or dedicated torque end fittings for different systems, reducing the need to change tools frequently. The HDC 16 design is made for 16mm hard tubing (Acrylic, PETG) and features a locking ring that compresses a rubber gasket to secure tubing and prevent pull-out. Grooved outer surfaces facilitate easier hand tightening while the compression ring includes cutouts in EK Quantum signature shape to display optional aesthetic color rings. The fittings are unbranded on the exterior for a clean, non-intrusive look and are compatible with EK-Quantum series components.
Suitable for
 Precision tightening of 16mm hard-tube compression fittings in custom liquid cooling systems
 System assembly and periodic maintenance where consistent torque is required
 Professional and hobbyist PC builders using Acrylic or PETG tubing
 Workshops or service centers that maintain multiple cooling loops and need spare torque wrench ends
Key specifications
 Pack quantity: 6 fittings
 Finish: silver
 Compatible interface: 1/4" imperial hex for torque wrench attachment
 Intended tube outer diameter: 16 mm (HDC 16 hard-tube compression fittings)
 Material characteristics: hard-tube compression design with rubber gasket and locking ring
 Origin: manufactured in Slovenia
How to use
Attach the 1/4" hex end fitting to the compatible torque wrench by seating the hex interface and securing it per the wrench manufacturer's instructions. Install the HDC 16 compression fitting onto the 16 mm hard tubing according to EK Water Blocks assembly guidance: slide the compression ring and any chosen aesthetic ring onto the tube, insert the tube into the fitting until the gasket seats, then tighten the compression ring using the torque wrench set to the recommended torque for the fitting material. Verify that the locking ring compresses the rubber gasket and that the tubing is held securely without deformation.
Usage recommendations
Use the torque wrench end fittings with a torque wrench calibrated for 1/4" hex attachments and follow EK Water Blocks recommended torque values for hard tubing fittings. Install aesthetic color rings (sold separately) prior to final tightening if desired. Store unused fittings in the original cushioned packaging to avoid damage and contamination of sealing surfaces.
