## Long description

The Alphacool HardTube 16/11mm 90° 0.4m is a transparent borosilicate glass tube designed for liquid cooling systems. With a 16 mm outer diameter and 11 mm inner diameter, a fixed 90° bend and a length of 0.4 m, this hard tube provides a rigid, tidy coolant path compatible with Alphacool HardTube connectors and standard fittings with a 11 mm nipple size. It is lightweight (approximately 200 g) and rated for a maximum operating pressure of 4 bar.
Advantages
Borosilicate glass offers high dimensional stability, chemical resistance and good tolerance to temperature fluctuations, which keeps the coolant path stable and visually clear over time. The rigid construction of the Alphacool HardTube maintains a neat, structured system layout and reduces the need for flexible hoses. The 90° pre-bent shape simplifies plumbing in tight layouts while remaining fully compatible with Alphacool HardTube connectors and common fittings that accept a 11 mm nipple.
Suitable for
Custom PC liquid cooling loops requiring rigid tubing
Systems where a clean, structured coolant layout is preferred
Builds that need a pre-formed 90° connection without bending on site
Setups using Alphacool HardTube connectors or fittings for 11 mm nipples

How to use
Install the HardTube into your liquid cooling loop by securing each end with compatible Alphacool HardTube connectors or fittings that support an 11 mm nipple. Ensure sealing surfaces and O-rings on the chosen fittings are clean and undamaged. Do not attempt to bend or reshape the tube; use the supplied pre-formed 90° piece where needed. After assembly, perform a pressure or leak test up to the rated 4 bar and inspect all connections before powering the system.
Usage recommendations
Store and handle the borosilicate glass tube carefully to avoid chips or cracks. Use the pre-formed 90° tube in areas where a precise, rigid elbow is required; do not heat or mechanically deform the tube. For reliable seals, pair the tube with Alphacool HardTube connectors sized for 16/11 mm tubing and replace any worn O-rings during maintenance.
