Here’s a ranking of the best selling Water cooling hoses. To give you a quick overview, we’ve added the most important information about each product. This page always stays fresh and updates automatically.
1. Corsair Hydro X Series XT Hardline
Corsair Hydro X Series XT Hardline Tubing completes the connections between custom Hydro X Series coolers and puts your coolant on display with crystal clear PMMA tubing. The tubing is designed for high pressure and high coolant temperatures, yet is easy to cut with a standard fine-toothed saw.

2. Alphacool Ice pipe set of 4
The most commonly used method for water cooling so far has been standard PVC hoses. Now, Alphacool offers another way to design a water cooling system. The HardTube variant brings more order to the system, creating a much more structured appearance. Brand new are the brass tubes, available in Black Chrome and Chrome, as well as acrylic tubes, carbon, and borosilicate glass. With the appropriate fittings and a very simple design, these can be connected or attached absolutely leak-proof. The PETG tube can be easily adjusted to the system with the right bending tool, without the need for additional angle pieces. To install the tubes into the system, they need to be cut to the appropriate length. PETG tubes require lower temperatures than acrylic to bend and are generally a bit more flexible and easier to handle. The perfect entry into the world of HardTubes.

3. Alphacool Ice pipe satin 13/10mm - set of 4
The most common hard tubes are clear and transparent. In addition, hard tubes made of brass and carbon have also gained popularity. Now, Alphacool offers the Ice Tube as part of its Ice product line. The surface visually resembles ice and feels like it too—somewhat rough, yet still smooth. The Ice Tube significantly alters the appearance within the system. Especially after filling the system, the actual effect is best observed. The water has the look of frozen ice. When the loop is illuminated with LEDs, clear hard tubes reflect the individual LEDs very well, but this is not the case with the Ice Tubes. Here, the light is diffused, resulting in a much softer and better illumination. The Ice Tube can be bent like all acrylic hard tubes using the appropriate bending tools. However, this noticeably changes the appearance of the Ice Tubes at the bends, no longer matching the original look. This can create an additional effect, but those who wish to maintain the Ice Tube appearance should use appropriate fittings for bends.

4. Aquatuning Hose
This new UV-active hose has significantly increased its brightness through an optimized use of UV-active additives. The flexibility and other technical specifications remain fully intact compared to conventional hoses. Therefore, the hose is ideal for creating the best possible lighting effect in a PC. Additionally, the hose can be slotted to be used, for example, as a cable channel.
Technical data: Allows for tight bending radii and is very flexible. The hose is transparent and fluoresces blue under UV light. Order quantity = hose length in meters. Packaging unit (for resellers): 30 m or 100 m (roll). Compatible with screw fittings and hose fittings. Not compatible with plug connections.
Fluorescent color: blue. Dimensions: 13 mm outer diameter and 10 mm inner diameter.
Please note: Due to transport and storage conditions, the hose may arrive somewhat "chilled" to the customer. Cold PVC hose tends to become a bit stiff. To enable optimal installation, we recommend storing the hose in a warm room for a few hours after receipt or briefly placing it in hot water (e.g., 60°). This will allow the hose to reach its optimal flexibility.
