Overview

The Corsair Hydro X Series XT Hardline Tubing is purpose-built for custom PC cooling enthusiasts who want their loops to look as good as they perform. Constructed from crystal-clear PMMA (polymethyl methacrylate), this 12mm outer diameter tubing offers outstanding optical clarity, letting you showcase vibrant coolant colors and monitor flow at a glance. Unlike softer tubing materials, PMMA holds its shape under pressure and resists the deformation that can occur with elevated coolant temperatures, maintaining clean lines up to its rated 60°C maximum operating temperature.

Designed within the Corsair Hydro X ecosystem, this tubing pairs seamlessly with Corsair's 12mm compression fittings, rotary adapters, and other Hydro X components for a cohesive build. Each straight length can be cut to size with a fine-toothed hacksaw and bent using a heat gun and silicone insert for custom routing. While PMMA demands more precision and care than flexible tubing or even PETG alternatives, the payoff is a rigid, glass-like finish that elevates the visual impact of any custom cooling loop.

Frequently Asked Questions

The tubing has a 12mm outer diameter, designed to work with Corsair Hydro X Series compression fittings and other compatible 12mm hardline fittings.
It is made from crystal-clear PMMA (acrylic), which provides excellent optical clarity to showcase your coolant color while maintaining structural rigidity.
The tubing is rated for a maximum operating coolant temperature of 60°C, which is well within the range of most custom cooling loops under normal conditions.
Corsair recommends using a fine-toothed hacksaw to cut the tubing to your desired length. After cutting, deburr and chamfer the edges for a clean fit into compression fittings.
While designed for the Corsair Hydro X Series ecosystem, the standard 12mm outer diameter means it will work with most third-party 12mm hardline compression fittings.
