What customers say
This soft tubing earns high praise primarily for its exceptional clarity and long term reliability. Users confirm the Ultra Clear designation remains true, showcasing coolants beautifully without the yellowing common in lesser PVC. A generous three meter length is appreciated for complex builds. While initially stiff, the tubing becomes pliable with minor heat application, allowing for easy routing around tight corners. Crucially, customers report strong resistance to plasticizer leaching, ensuring system health and preventing buildup, which builds confidence in component longevity. The large outer diameter offers a robust aesthetic and high flow, though it requires planning in smaller cases. Overall, this tubing delivers top tier visual performance and dependable quality.
Know before you buy
This tubing has an inner diameter of 13 mm (1/2 inch) and an outer diameter of 19 mm. It is important to match these measurements with your compression fittings to ensure a leak-free seal.
The AlphaTube HF is designed with a 65-70 A-Shore hardness, which provides a balance between flexibility and structural integrity. While it is easy to route, it is engineered to resist kinking during standard bends in a custom loop.
The tubing is rated for a working temperature range of -10 to 80°C. It is suitable for most standard custom water cooling loops, but you should ensure your coolant temperatures remain within this range during operation.
Each package contains a single 3-meter (9.8-foot) length of tubing. This is typically enough to complete a full custom loop for a standard desktop chassis with plenty of room for error.
While PVC tubing is highly durable, it can eventually experience some discoloration or clouding depending on the type of coolant used and exposure to UV light. Using a high-quality, clear coolant and avoiding harsh additives can help maintain its clarity for longer.
