Hmm… I use cheapass silicone tubing, 5mm ID 7mm OD and wear hasn’t been an issue. Perhaps you compress the tube too much. The tube should be held shut so that no liquid flows backwards but also not compressed so much that it wears the tubing out. Your pump should have a variable tensioner on it.

Perhaps also you don’t have enough rollers. At least one roller needs to be in full contact with the tubing (compressing) so that there is no backflow.
