## Summary description

Set of six EK Water Blocks EK-Quantum Torque STC compression fittings in black, designed for 10/13 mm tubing.

Suitable for PC water-cooling builds where stable, vibration-resistant joints and neat cable routing are required.

## Long description

Set of six EK Water Blocks EK-Quantum Torque STC compression fittings in black for 10/13 mm tubing. These compression fittings are engineered to create secure, leak-resistant connections between soft or hard tubing and threaded water-cooling components in custom PC loops. The pack includes six identical fittings intended for use where stable, low-vibration joints and a clean, compact routing of tubing are needed.
Advantages
These compression fittings provide a reliable mechanical seal for 10/13 mm inner/outer diameter tubing, reducing the need for additional clamps. The black finish offers a discreet aesthetic that integrates with most PC builds and helps hide minor scratches or fingerprints. Designed for repeated assembly, the fittings enable secure reconnection after maintenance while maintaining consistent compression force to prevent leaks.
Suitable for
Custom PC water-cooling loops using 10/13 mm soft or hard tubing
Connections to water blocks, radiators, pumps and reservoirs with compatible threads
Builds requiring compact, vibration-resistant tubing joints
Key specifications
Color: black
Compatible tubing diameter: 10 mm inner / 13 mm outer (10/13)
Pack quantity: 6 fittings
Type: compression fitting (torque-style)
Material: metal construction with sealing element (manufacturing material not specified)
How to use
Install the fitting by sliding the compression ring and nut over the tubing, inserting the tubing onto the barb or thread interface of the water-cooling component, then tightening the nut until the compression ring engages and forms a seal. Ensure tubing is cut squarely and pushed fully onto the mating surface before compressing. Hand-tighten initially and finish with an appropriate tool if required to achieve a secure fit; avoid over-tightening that could deform tubing or damage threads.
Usage recommendations
Before powering the system, perform a leak test by filling the loop and running the pump with the system powered off (or with only the pump powered) for several hours. Recheck fittings after the first coolant cycle and periodically during maintenance. Use tubing rated for PC liquid cooling and compatible coolant to ensure long-term sealing performance.
