## Summary description

Replacement torque wrench end fittings EK Water Blocks EK-Quantum Torque 6-Pack HDC 14 are 1/4" hex heads supplied in a pack of six. Designed as accessory fittings for torque wrenches, these imperial-sized HDC 14 hex keys facilitate precise fastening of fittings and components. Made in Slovenia, suitable for PC water-cooling assembly and maintenance tasks.

## Long description

EK Water Blocks EK-Quantum Torque 6-Pack HDC 14 replacement end fittings are a set of six 1/4" (imperial) hex heads designed for use with compatible torque wrenches and EK-Quantum series fittings. Manufactured in Slovenia, these HDC 14 fittings are intended for use with hard tubing such as acrylic and PETG and serve as accessory parts for precise fastening during PC water-cooling assembly and maintenance. The pack contains six identical hex end fittings protected in foam packaging to reduce the risk of damage during transport.
Advantages
These end fittings provide a precise 1/4" hex interface for torque-controlled tightening, helping achieve consistent fastening of compression fittings and related components. Their design includes an external grooved surface for easier hand tightening and a compression locking ring that compresses the internal rubber gasket to prevent tube pull-out. The fittings feature cutouts in the compression ring to accommodate interchangeable aesthetic color rings (sold separately), allowing a non-branded, minimal appearance that integrates with EK-Quantum series products.
Suitable for
Assembly and maintenance of PC custom water-cooling loops using acrylic or PETG hard tubing
Tightening or replacing compression fittings where a 1/4" hex torque interface is required
Tasks requiring multiple matching end fittings for consistent torque application
Key specifications
Quantity: 6 pieces per pack
Hex interface size: 1/4" (imperial)
Compatibility: designed for HDC 14 hard-tube compression fittings
Suitable tube types: solid tubing such as acrylic and PETG
Material origin: manufactured in Slovenia
Packaging: box with protective black foam cushioning
How to use
Install the 1/4" hex end fitting onto a compatible torque wrench and align the compression fitting components on the hard tubing. Apply torque according to the fitting manufacturer's specified torque values, using the hex head to achieve controlled tightening. Ensure the compression ring compresses the internal rubber gasket around the tube to secure the connection and prevent pull-out. If aesthetic color rings are to be used, screw them onto the fitting before installing the compression locking ring as those rings are sold separately.
Usage recommendations
Use a torque wrench calibrated for small imperial hex fittings and follow EK Water Blocks' guidance for torque settings on HDC 14 compression fittings. Inspect the rubber gasket and tube ends for damage before assembly and pack unused fittings in their foam-protected box to avoid dents or contamination.
