Torque wrench end fitting EK Water Blocks EK-Quantum Torque HDC 14, black, 1/4 inch hex

EK-Quantum Torque HDC 14 end fitting is an accessory designed by EK Water Blocks to work with compatible torque wrenches and 1/4" (imperial) hex drive tools. Finished in black, this end fitting allows precise application of torque when fastening hard-tube water-cooling fittings and related components in PC liquid-cooling loops. It provides a compact interface between a torque wrench and 14mm hard-tube compression fittings, enabling controlled tightening to specified torque values during assembly and maintenance.

Advantages

The black 1/4" hex end fitting delivers a non-intrusive appearance while enabling consistent and repeatable torque application, reducing the risk of over-tightening or under-tightening compression fittings. Its compact design is compatible with standard 1/4" torque wrench drives and helps maintain a clean aesthetic when used with EK-Quantum series components. The fitting facilitates accurate fastening in confined spaces where precise torque control is required.

Suitable for

• Tightening 14mm hard-tube compression fittings on PC water-cooling loops
• Maintenance and reassembly of liquid-cooling components requiring specific torque settings
• Use with compatible torque wrenches and 1/4" hex drive tools

Key specifications

• Drive interface: 1/4" hex (imperial)
• Finish: black
• Compatible with 14mm hard-tube compression fittings
• Intended use: precise torque application for water-cooling fittings

How to use

Attach the Torque HDC 14 end fitting to the 1/4" hex drive of a compatible torque wrench. Place the mating end over the compression fitting's nut and apply torque gradually following the torque value recommended for your fittings. Ensure the hard tubing and fitting are properly seated before tightening. Use steady, controlled turns until the wrench indicates the preset torque has been reached, then stop to avoid over-tightening.

Recommendations

Use this end fitting with a torque wrench calibrated for small imperial drives and follow manufacturer torque specifications for 14mm hard-tube fittings. Inspect fittings and tubing for correct seating and gasket condition before each tightening operation to ensure leak-free connections.
