The Alphacool Eisrohr PETG HardTube givse the user the possibility to create a very special look. With a wall thickness of 3 mm, the tubes are very strong, but can still be bent without great effort and they are easy to fit. PETG HardTubes are probably the easiest to bend compared to those made of other materials. They require significantly less heat than PMMA HardTubes, for example. The Alphacool Eisrohr PETG HardTubes are absolutely clear and will look great in almost every water cooling loop. When cutting the tubes, make sure to chamfer the edges with fine file , sandpaper or the Alphacool Strong Guy pipe and hose deburrer, as sharp edges can damage the O-rings of fittings.
