Pre-bent 90° chrome brass tubing

Alphacool Brass HardTube is a set of pre-bent 90° chrome-plated brass tubes for custom liquid-cooling loops. Each pack contains one 20 cm and one 40 cm piece with 13 mm outer diameter and 12.2 mm inner diameter. The .8 mm wall thickness keeps the tubes rigid yet easy to cut and deburr during installation. Chrome finish resists scratches under normal handling.

Ideal for single-loop showcase builds

Suits enthusiasts who want a rigid, reflective aesthetic in a single-loop system and are comfortable cutting and deburring hard tubing. Not suited for builders who prefer flexible tubing, need longer continuous runs without joints, or want a matte or coloured finish instead of chrome.

Two pre-cut lengths cover simple layouts

The 20 cm and 40 cm sections handle straightforward CPU-to-GPU or CPU-to-radiator runs in compact cases. More complex loops with multiple components or larger chassis will require additional straight tubing and fittings beyond the two pieces supplied.

Soalan tentang produk ini

What fittings are required to connect the 13 mm outer-diameter brass tube to a water-cooling loop?

Use compression fittings designed for 13 mm OD hard tubing; the 12.2 mm inner diameter and 0.8 mm wall thickness match standard 13 mm fittings.

Can the pre-bent 90° chrome tube sit alongside existing acrylic or PETG runs without galvanic issues?

Brass is a copper alloy, so pair it only with nickel-plated or brass fittings; avoid bare aluminium blocks or radiators in the same loop.

How can I verify the 20 cm and 40 cm legs are correctly oriented after installation?

The 90° bend joins a 20 cm short leg and a 40 cm long leg; confirm the chrome finish is unmarked and coolant flows without leaks.
