## Long description

EK Water Blocks EK-Quantum Torque STC-10/13 Silver, 1/4" hex is a torque wrench end fitting in a silver finish with a 1/4" imperial hex interface. Manufactured in Slovenia, this accessory is intended as a replacement or complement for EK torque tools and fittings, providing a precise interface for controlled tightening in water-cooling assemblies and other small-assembly tasks. It is compatible with EK-Quantum STC 10/13 soft-tube compression fittings designed for 10/13 mm (inner/outer diameter) flexible tubing such as PVC, EPDM, Norprene, silicone and other compatible soft tubes.
Advantages
The fitting offers a compact, minimalistic design without visible branding, finished in silver for a neutral appearance. Its 1/4" hex connection provides compatibility with standard imperial torque wrench bits, enabling accurate torque transfer. The product is machined to interface with EK-Quantum STC 10/13 compression fittings, supporting controlled tightening and repeatable results during installation or maintenance of water-cooling loops and small mechanical assemblies.

Key specifications
Finish: Silver
Hex interface: 1/4" imperial hex
Compatible tube size (fitting family): 10/13 mm (ID/OD) soft-tube compression fittings
Intended use: Torque wrench end fitting for precision tightening
Manufacturing origin: Slovenia
How to use
Attach the EK-Quantum Torque STC-10/13 end fitting onto a compatible 1/4" hex torque wrench or bit holder. Engage the fitting with the mating EK-Quantum STC 10/13 compression fitting and apply torque per the manufacturer's recommended values for the tubing and fitting in use. Ensure the compression ring and rubber gasket of the mating fitting are correctly positioned before tightening to achieve secure sealing and to prevent tube pull-out. Use smooth, controlled turns to reach the required torque and avoid over-tightening.
Usage recommendations
Verify compatibility with the specific flexible tube material (PVC, EPDM, Norprene, silicone, etc.) and follow EK Water Blocks' guidance for torque settings where provided. Inspect the fitting and mating parts for damage before use and replace any worn rubber gaskets to maintain sealing performance.
