Corsair CX-9059004-WW Hydro X Series XT Hardline Tubing

The Corsair Hydro X Series XT Hardline Tubing is purpose-built for custom PC liquid cooling loops where both performance and aesthetics matter. Constructed from PMMA — a rigid acrylic known for its clarity and structural integrity — this tubing resists warping and deformation even under high system pressures and elevated coolant temperatures. The 12mm outer diameter is designed to work seamlessly with Corsair's Hydro X Series hardline compression fittings, ensuring leak-free connections throughout your loop without the need for adapters or third-party components.

What sets this tubing apart visually is its satin finish, which produces a frosted matte appearance that diffuses light passing through the tube. This creates a distinctive look compared to standard transparent hardline tubing, especially when paired with colored coolant or RGB-lit reservoirs and fittings. Each tube comes in a straight length ready to be cut to size with a fine-toothed hacksaw and bent with a heat gun for custom routing. While the rigid PMMA material demands more precision and patience than soft tubing, the result is a polished, professional cooling system with clean lines and secure connections.
