## Long description

EK-Quantum Torque Micro HDC 12 - Black is a compact premium brass fitting for solid tubing such as acrylic, PETG and brass tubing. With an installed height of 11.5 mm and an outer diameter of 16 mm, this fitting offers a much smaller footprint than standard Torque HDC 12 fittings while remaining compatible with EK liquid-cooling components.
Advantages
The fitting uses a high-quality EPDM rubber gasket in the Torque Micro compression ring to securely grip solid tubes. CNC-machined brass construction with a satin black finish provides corrosion-resistant metal durability. An internal 9 mm hex Allen key socket in the barb helps protect surrounding components during installation.
Suitable for
Compact PC water-cooling loops with limited space
Solid tubing materials: acrylic, PETG, brass
