## Long description

The Alphacool HardTube 16/11mm 90° is a transparent borosilicate glass tube designed for liquid cooling systems. With a length of 0.6 m and a 16 mm outer diameter (11 mm inner diameter), this rigid tube provides a tidy, structured look and is compatible with Alphacool HardTube connectors. The tube withstands typical chemicals and temperature fluctuations used in PC water cooling and is intended for custom cooling loops where durability and appearance are important.
Advantages

The rigid form improves internal cable/tube management and gives a clean, professional appearance compared with flexible PVC hoses.
