EK-Quantum Torque Drain Valve - Black Nickel is a premium fitting acting as a perfect draining point in your system. It features a secure cap, in form of a Torque fitting compression ring, and it can even fit an aesthetic color ring for HDC 16 Torque fittings. The secure-cap does not allow you to accidentally open, or leave open the drain valve.This drain valve has an advantage over the traditional ball valves in terms of size. It has a smaller footprint, secure locking, and an easy open/close mechanism that works on a slide. It has a male thread on one end, allowing you to screw it directly into a G1/4\" female port on any water cooling component without the use of an adapter fitting as traditional ball valves do.Made of black nickel-plated CNC machined brass.Technical specifications:- Threading: G1/4\"- Thread length: 4.5mm- Diameter: 23mm- Installed height: 29mm
