All requirements for a connection are fulfilled here: Highflow, shape, processing and colouring. Uncompromising development and manufacture have made icicles what they are. In brilliant chrome and matt, deep black, there are two finishes that fit perfectly into any system: with special processes, the coatings are firmly bonded to the substrate, the longevity of the intense colours is guaranteed and the coating does not flake off. Every connection now also has the Alphacool logo, which makes it unmistakable in addition to its special shape. Due to the bevelled edges of the union nut, the O-ring is pressed very tightly against the HardTube, making it even tighter than its predecessors. This ensures greater safety during transport. Who likes it colorful has three differently colored O-rings in the scope of supply. With existing UV lighting these shine even in appropriate color.
