EK-Quantum Torque Micro HDP 12 fittings are EK\'s new push-in hard-tube fittings designed for use with 12mm solid tubing such as Acrylic and PETG. They are stealthy and made to be as small as possible, and with NO added branding at all. They are engineered specifically for captive tubing - like runs between two GPU water blocks, or from a GPU to the distro plate. Most importantly, the tube should not be able to move when using these fittings.The solid tube is gripped by the high-quality EPDM rubber gasket inside the Torque Micro HDP fitting. The fitting is made of nickel-plated CNC-machined brass.These fittings are guaranteed to be compatible with all other EK Water Blocks liquid cooling products.Technical data:- Finish: Nickel- Material: Brass- Thread: G1/4\" BSP; 4.5mm male thread length- Supported tube: 12mm OD- The outer diameter of a fitting: 16.5mm- Installed height: 10mm- Compatible solid tubing: Acrylic, PETG, Copper, Brass, Stainless Steel
