Fitting EK Water Blocks EK-Quantum Torque 6-Pack STC 10/13

EK-Quantum Torque 6-Pack STC 10/13 contains six EK-Torque soft-tube compression fittings for 10/13 mm (ID/OD) flexible tubing. Made from CNC-machined brass with a high-quality nickel finish, each fitting uses rubber O-rings for sealing and a compression locking ring to prevent tubing from being pulled off the barb. The fittings are compatible with PVC, EPDM, Norprene, silicone and other similar flexible tubes and are designed to integrate with EK-Quantum series components. Colored aesthetic rings (sold separately) can be fitted beneath the compression ring for visual customization.

Advantages

The fittings provide a secure, leak-resistant connection for 10/13 mm soft tubing thanks to a compressing locking ring and quality rubber O-rings. CNC-machined brass construction with a nickel finish offers durable corrosion resistance and a uniform appearance. Grooved outer surfaces allow easier hand tightening while the internal 8 mm hex socket permits tool-assisted installation when needed. The design is modular and visually compatible with EK-Quantum products, and the aesthetic ring option enables customization without added branding on the fitting body.

How to use

Push the 10/13 mm flexible tube onto the barb until it seats fully. Slide the compression ring over the tubing and thread it onto the fitting until it compresses the tube wall under the ring, preventing the tube from being pulled off. Hand-tighten using the outer grooves for grip; if additional tightening is required, use an 8 mm Allen key in the internal hex socket on the barb with care to avoid over-torquing. Fit any optional aesthetic color ring onto the fitting before mounting the compression ring. Ensure rubber O-rings are in place and undamaged before assembly.

Recommendations

Do not apply excessive force when using an 8 mm Allen key on the internal hex to avoid damaging fittings or other loop components. Use compatible flexible tubing and check O-rings for wear; replace rings or fittings if any damage or leaks are detected. Aesthetic rings are sold separately and should be installed prior to the compression ring.
