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 11.5mm, which is 23% 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.
