EK-Quantum Torque series products received the prestigious iF Design Award. A robust and industrial aesthetic sets the Torque family apart by highlighting the precise manufacturing processes used to create them. In addition, enthusiasts can add a unique color ring to give a personal accent to the fitting line. The Torque family of fittings offers a secure and modular system of connections between liquid cooling components and tubing within a PC. Quantum Torque series products cover angled adapters, rotary and static extenders, splitters, G1/4" plugs, drain valves, fittings, and much more. he locking ring prevents solid tube to be pulled out of the fitting by compressing the rubber gasket underneath the ring. The grooves on the outside allow for easier hand tightening. The compression ring has cutouts in EK Quantum signature shape allowing for the colored aesthetic ring to be shown. The colored rings are available in many colors and are screwed onto the fitting before the compression locking ring. The fitting barb and the compression rings are first nickel-plated, followed by the second plating with genuine gold. Both are made of CNC machined brass and the seal is made of quality rubber O-rings.
