Hoses are the lifelines in the water cooling system! Here is the latest generation from Alphacool! Depth, bold colors and comfortable handling when laying and connecting were our specifications for the hose development. The product are hoses in different sizes and colors like red, green, blue or black. In the development of the hoses, we deliberately worked to ensure that no color particles from the coolants would have to pollute the water circuit; instead, the power of the color comes from the hose. In addition to the color, the laying and kinking behavior of hoses is of course of great interest. The bridging of tight bending radii and pleasant handling in tricky places were also given priority here. This was optimized to perfection by using various plastic compounds, and we now have a hose that reconciles the sometimes development-inhibiting, opposing goals and will convince both the beginner and the advanced water cooling user! The production in Germany promises consistently high quality. Manufacturing with years of experience ensures that only the best product is always sold.
