Torque wrench end fitting EK Water Blocks EK-Quantum Torque STC-12/16, silver, 1/4 inch hex

EK Water Blocks EK-Quantum Torque STC-12/16 torque wrench end fitting in silver is an accessory designed to interface with EK-Quantum Torque tools and to assist with precise tightening of fittings in liquid-cooling assemblies. The fitting uses a 1/4" imperial hex connection and is manufactured in Slovenia. It is intended for use with EK-Quantum STC 12/16 soft-tube compression fittings, providing a compatible, tool-friendly contact point for installation and maintenance of PC cooling loops.

Advantages

The silver-finish end fitting offers a minimalistic design without visible branding and provides a stable hex contact for torque tools to ensure controlled tightening. Its compact, metal construction reduces slippage and wear compared with improvised adapters, while the 1/4" hex interface is compatible with standard torque wrenches and drivers. The part is specifically shaped to work with EK-Quantum STC 12/16 soft-tube compression fittings, supporting consistent and repeatable installation torque.

Suitable for

• Installation and maintenance of PC liquid cooling loops using EK-Quantum STC 12/16 soft-tube compression fittings
• Tightening or loosening fittings where a 1/4" hex torque interface is required
• Work with flexible tubing types such as PVC, EPDM, Norprene, silicone and other compatible soft tubing when used with corresponding compression fittings

Key specifications

• Finish: silver
• Hex connection: 1/4" (imperial)
• Compatibility: designed for EK-Quantum STC 12/16 soft-tube compression fittings
• Material: metal construction suitable for torque tool contact
• Origin: Slovenia

How to use

Attach the torque wrench end fitting to the drive of a compatible torque wrench or 1/4" hex driver. Place the fitting onto the compression fitting that accompanies EK-Quantum STC 12/16 soft-tube hardware and apply controlled torque according to the compression fitting manufacturer’s recommended values. Ensure the soft tube is properly seated in the fitting and that any aesthetic rings or compression rings are pre-installed if required before final tightening.

Recommendations

Use a calibrated torque wrench and follow EK-Quantum STC 12/16 fitting torque specifications to avoid over-tightening. Inspect the interface and tubing after initial use and periodically during maintenance to confirm seals and compression rings remain secure.
