## Long description

EK-Quantum Torque 6-Pack fittings by EK Water Blocks are premium brass compression fittings finished in satin black, supplied as a set of six for custom PC liquid-cooling loops. Each fitting has an overall height of 19 mm and is designed to work with flexible soft tubing with a 12/16 mm (ID/OD) profile, corresponding to a 4.5 mm wall compatibility when using appropriate tubing types. Machined from CNC brass and finished with a high-quality satin coating, these fittings include rubber O-ring seals and a compression-style locking ring that secures flexible tubing onto the barb.
Advantages
The EK-Quantum Torque fittings combine durable metal construction and precise CNC machining for reliable, repeatable connections in cooling loops. The compression locking ring design compresses the tubing wall under the ring to prevent pull-off while external grooves enable easier hand-tightening. Their satin black finish provides a consistent, low-profile appearance with no visible branding, and the fittings are compatible with optional interchangeable aesthetic color rings for personalization. The fittings are part of a broader Torque family that includes angled adapters, extenders and other connection options, enabling a modular approach to loop design.
Suitable for (tasks / use cases)
Building or maintaining custom PC liquid-cooling loops using soft tubing (12/16 mm ID/OD compatible)
Connecting radiators, pumps, reservoirs and water blocks where durable metal compression fittings are required
Upgrading standard plastic fittings to CNC-machined brass fittings for improved longevity and appearance
Systems where a low-profile, satin black aesthetic is desired, with option to add colored accent rings
Key specifications
Material: CNC-machined brass (fitting body and compression ring)
Finish: Satin black coating
Pack quantity: 6 fittings
Fitting height: 19 mm
Tubing compatibility: designed for flexible soft tubing with 12/16 mm (ID/OD) profile
Seal type: rubber O-ring
Compression-style locking ring for secure tube retention
How to use
Prepare tubing by cutting the end square and ensuring the inner and outer diameters match the 12/16 mm profile specified for the fittings. Slide the optional aesthetic ring (if used) onto the tubing, then push the tubing firmly onto the barb until it seats against the fitting shoulder. Screw the compression locking ring onto the fitting and hand-tighten until the tubing wall is compressed under the ring and the connection feels secure; the external grooves assist manual tightening. Verify the rubber O-ring is seated correctly to ensure a leak-free seal. After assembly, pressure-test the loop according to standard custom cooling procedures before powering the PC.
Usage recommendations
Use these fittings with compatible flexible tubing materials such as PVC, EPDM, Norprene or silicone. Do not overtighten the compression ring with tools; hand tightening is sufficient and preserves the finish and threads. Inspect O-rings periodically and replace them if they show wear. Perform a leak test after installation and before full system operation. Colored aesthetic rings are sold separately and should be installed prior to fitting the compression ring.
