## Long description

EK Water Blocks EK-Quantum Torque STC-10/16, Silver, 1/4" hex is a torque wrench end fitting created for controlled tightening of compression fittings in PC liquid-cooling assemblies. Manufactured in Slovenia, this silver end fitting accepts a 1/4" (imperial) hex key and is intended for use with compatible torque wrenches to apply precise torque to soft-tube compression fittings and valves used in water-cooling loops.
Advantages
This torque wrench end fitting provides a compact, minimalist design without visible branding and is made to interface cleanly with EK-Quantum 10/16mm soft-tube compression fittings. The 1/4" hex receptacle enables use with standard imperial hex torque tools for repeatable and accurate torque application. Grooved outer surfaces allow easier hand tightening when needed, while the construction supports the correct engagement with compression rings and locking rings used on soft-tube fittings.
Suitable for
 Applying controlled torque to PC liquid-cooling compression fittings
 Installation and maintenance of EK-Quantum STC 10/16 soft-tube fittings
 Tightening valves and threaded components in water-cooling loops
 Use where a 1/4" (imperial) hex torque interface is required
Key specifications
 Compatibility with 10/16 mm soft-tube compression fittings
 Drive interface: accepts 1/4" (imperial) hex key
 Finish color: silver
 Designed for use with soft tubing types such as PVC, EPDM, Norprene, silicone or other compatible flexible tubes

 Origin: Slovenia
How to use
Fit the EK-Quantum Torque STC-10/16 end fitting onto the hex drive of a compatible 1/4" torque wrench or hex key tool. Engage the fitting with the compression fitting or valve thread, then apply the specified torque using the torque wrench to achieve a consistent and controlled seal. For final hand adjustments, use the grooved outer surface to turn the fitting without tools if required. Ensure the compression ring and locking ring are correctly positioned on the soft tube before final torqueing to prevent tube slippage.
Usage recommendations
Use this end fitting only with compatible EK-Quantum STC 10/16 compression fittings and appropriate torque settings recommended for soft-tube assemblies. Avoid over-tightening beyond manufacturer torque specifications to prevent damage to threads, gaskets or tubing. When installing colored aesthetic rings, assemble them according to the fitting manufacturer’s instructions and confirm proper seating of the rubber gasket beneath the locking ring for secure retention.
