EK-Quantum Torque (Adapter Fitting) - Black is a rotatable angled (45°) adapter fitting with a G1/4" thread. Shaped like a separation cylinder, it is very stable and there is no movement in the swivel joint. This Quantum Line adapter is made from CNC-machined brass with a high-quality satin black finish, while the seal consists of high-quality rubber O-rings. The black fittings of the EK-Quantum Torque series are intentionally left unpainted on the inside to minimize the level of potential contaminants in the loop. It is an extremely safe and robust part that will last for many future builds. The adapter allows for the connection of fittings with a G1/4" thread, expanding the tubing options in your water-cooled system and enabling easier bends as well as better accessibility.
