Brass HardTube 90° 13mm OD

This pre-bent brass tube provides a 90-degree corner for custom liquid-cooling loops. The 13 mm outer diameter matches standard hard-tube fittings. Deep black gloss coating resists scratches under normal handling. It suits builders who want rigid tubing aesthetics without bending tools.

Install with deburring step

Cut ends must be smoothed with fine sandpaper or a deburrer before assembly. Sharp edges left from cutting will damage fitting O-rings and cause leaks. The .8 mm wall is rigid yet thin enough to saw by hand without powered equipment. No heat bending is required because the angle is factory-formed.

Fixed 10/30 cm legs

The 30 cm and 10 cm straight sections set the exact offset between components. Loops needing longer reach or a different bend radius cannot use this part. Inner diameter of 12.2 mm supports typical coolant flow rates for CPU and GPU blocks. Builders requiring extended runs must add straight tubing sections.

Questions about this item

How do I confirm the Alphacool Brass HardTube 13mm OD 90° Deep Black is seated correctly after installation?

After fitting the 90 degree brass tube with its 13 mm outer diameter and 12.2 mm inner diameter, run the loop under pressure and check every joint for leaks; the 0.8 mm wall thickness and gloss black coating should show no deformation or coating damage at the fittings.

What comes with the Alphacool Brass HardTube 18607 and which parts must be sourced separately?

The package contains one pre-bent 90 degree brass tube with a 30 cm long side and a 10 cm short side; compatible 13 mm compression fittings, deburring tool, cutting tool and coolant are not included and must be purchased separately.

Which length variant of the Alphacool Brass HardTube 13mm OD 90° should I choose for my loop?

This version provides a fixed 30 cm long leg and a 10 cm short leg; select it when your bend geometry matches those exact dimensions, otherwise choose a straight tube or a different pre-bent length from the Alphacool range.
