EK-Quantum Torque Micro HDC 12 is a premium 12mm fitting made for solid tubing, such as acrylic, PETG, and brass. A much smaller footprint will allow tube placement in places where a regular fitting would be too large or inconvenient. It was named Micro due to an installed height of only 7mm, which is shorter than standard Torque HDC 12 fittings. The outer diameter of the fitting is also significantly smaller than its bigger brother, with only 16mm across the fitting.
