Compression Ring EK Water Blocks EK-Quantum Torque 6-Pack STC 16 Blue

EK-Quantum Torque Compression Ring 6-Pack STC 16 in blue is a CNC-machined aluminium locking ring designed for use with EK-Quantum Torque STC 10/16 and 12/16 series fittings. It is not a standalone product and must be used together with a compatible Torque fitting barb. The ring compresses the tubing wall beneath it to prevent flexible tubing from being pulled off the fitting, while external grooves provide improved grip for hand tightening. The ring features cutouts in the EK-Quantum signature shape so an aesthetic coloured ring (sold separately) can be visible when assembled.

Advantages

The compression ring is made from durable CNC-machined aluminium with a high-quality blue finish, offering corrosion resistance and consistent mechanical compression. Its outer grooves make manual installation easier, and the signature cutouts allow visual customization when combined with compatible aesthetic rings. The pack contains six identical rings suitable for multi-fitting custom liquid-cooling loops.

Suitable for

• Custom PC water-cooling loops using EK-Quantum Torque STC 10/16 or 12/16 fittings
• Applications requiring secure connection of flexible tubing to barbed fittings
• System builds where visual customization with coloured rings is desired

Key specifications

• Compatibility: EK-Quantum Torque STC 10/16 and 12/16 series fittings only
• Material: CNC-machined aluminium
• Finish: Blue
• Pack contents: 6 compression rings

How to use

Slide the compression ring over the flexible tube, position the tube onto the barb of a compatible EK-Quantum Torque STC fitting, then screw the compression ring down onto the fitting to compress the tubing wall and secure the connection. Ensure the correct STC size (10/16 or 12/16) is used with matching fittings. The aesthetic coloured ring (if used) should be installed before fitting the compression ring as designed.

Recommendations

Use only with EK-Quantum Torque STC 10/16 or 12/16 fittings and compatible flexible tubing. Do not attempt to use the compression ring as a standalone connector; verify sizes before assembly and tighten by hand using the outside grooves for grip. Store spare rings in a dry place to avoid surface contamination.
