Torque wrench end fitting 1/4" EK Water Blocks EK-Quantum Torque 6-Pack HDC 16 Silver

EK-Quantum Torque 6-Pack HDC 16 Silver from ek water blocks is a set of six silver torque wrench end fittings with a 1/4" hex interface, designed as replacement heads or accessories for torque wrenches used in precision PC water-cooling assembly. Manufactured in Slovenia, these fittings are compatible with EK-Quantum series hard-tube compression fittings and intended to enable controlled, repeatable torque application when installing or maintaining components that use 16 mm hard-tube compression fittings for acrylic or PETG tubing.

Advantages

The set provides six identical torque wrench end fittings that allow for precise tightening of compression fittings and fasteners with a 1/4" hex key interface. Constructed to match EK-Quantum hard-tube compression fittings' form factor, the fittings include an outer groove pattern for improved grip during hand tightening and a locking ring design that compresses the internal gasket to prevent tube pull-out. Packaged with internal foam protection, the multipack minimizes transport damage and supports consistent installation quality.

Suitable for

• Assembly and maintenance of PC liquid-cooling loops that use 16 mm hard tubing (acrylic, PETG)
• Replacement of worn or lost torque wrench end fittings with a 1/4" hex interface
• Situations requiring repeatable, controlled torque on compression fittings and related fasteners
• Integration with EK-Quantum series components where compatible 16 mm fittings are used

Key specifications

• Quantity: six identical torque wrench end fittings
• Interface size: 1/4" hex (imperial) for torque wrench connection
• Intended fitting size: compatible with 16 mm hard-tube compression fittings
• Finish/color: silver
• Material characteristics: metal construction matching EK-Quantum fitting geometry (designed for use with acrylic and PETG hard tubing)
• Packaging: boxed with black foam cushioning for transport protection

How to use

Attach the 1/4" hex end fitting to a compatible torque wrench, set the torque wrench to the desired torque value recommended for your compression fittings and tubing material, and engage the fitting on the fastener or compression nut. Use the torque wrench to apply a controlled, repeatable torque until the wrench indicates the set value. For hand-tightening prior to torqueing, use the outer grooves on the fitting for improved grip. When installing hard tubing, ensure the locking ring compresses the internal gasket to secure the tube and prevent pull-out; aesthetic colored rings can be fitted onto the compression ring where compatible and are sold separately.

Usage recommendations

Use torque settings appropriate for 16 mm hard-tube compression fittings and the tubing material (acrylic or PETG) to avoid over-tightening. Verify compatibility with your specific EK-Quantum fittings before use and keep spare aesthetic rings if you plan to customize the appearance. Store the fittings in their cushioned box to prevent damage between uses.
