Torque wrench end fitting EK Water Blocks EK-Quantum Torque 6-Pack HDC 12

EK-Quantum Torque 6-Pack HDC 12 is a set of six compression fittings designed for 12 mm hard tubing such as Acrylic and PETG. These premium EK fittings feature a minimal, unbranded appearance and support interchangeable aesthetic rings (sold separately). The pack is shipped in black foam cushioning to protect the fittings during transport.

Advantages

The locking ring compresses a rubber gasket to prevent the solid tube from being pulled out, while exterior grooves make hand tightening easier. The compression ring includes cutouts in the EK-Quantum signature shape to reveal the optional colored aesthetic ring. Manufactured for compatibility with EK-Quantum series components and intended for reliable, leak-resistant tube connections.

Suitable for

• Custom PC liquid cooling loops using 12 mm hard tubing
• Acrylic or PETG rigid tubing installations
• Systems where a minimal, unbranded aesthetic is preferred

How to use

Slide the compression ring and any chosen aesthetic ring onto the prepared 12 mm hard tube, insert the tube into the fitting until it seats against the internal stop, then tighten the locking ring by hand until the rubber gasket is compressed and the tube is secured. Do not overtighten; ensure the tube is straight and fully inserted before final tightening. Install the fittings onto compatible components according to the cooling loop layout.

Recommendations

Verify tubing outer diameter and cut ends square before installation. Use only compatible EK aesthetic rings if desired. Inspect fittings and gaskets for damage after shipping and replace any damaged parts prior to use.
