The Aquatube is a reservoir that couldn't be more practical. Its large opening allows for easy filling and provides optimal flow control. For individual installation of (not included) connections and lighting modules, there are a total of five G1/4 threads available on the bottom and side wall. Matching sealing screws for unused connection threads are included. Five M4 threads on both the top and bottom enable easy mounting to or within the case. Optional accessories include installation panels made of stainless steel and aluminum. The Aquatube is completely leak-proof and can be installed in any position. With this reservoir, filling your water cooling system becomes a breeze. In addition to its excellent functionality, it impresses with a unique design. The reservoir is turned and milled from solid Delrin, making it extremely durable. The Delrin white version of the Aquatube features four additional holes at the bottom for mounting 5 mm LEDs. The translucence of the material allows for spectacular lighting effects to be achieved.
