Ok, I'm testing a tube that comes with industrials detergent dosing pumps(my company sells sells this so I grab a piece of tube to test)

https://www.rehau.com/download/14654...-rau-pe-en.pdf

The only indication I see writen on the tube is "REHAU RAU-PE"

The tube is semi-rigid but fits well in the doser and KHD so... it works for me... checked today still no bubbles.
