Hello.I have a problem with the dialysis tubing. On four machines in one center. There are strange cracks on them, all along their length. Two of the machines are SW 9.1E and two are SW 9.1B. The machines have been used a bit. Has anyone encountered a similar problem? The machines use normal acidic and dry bicarbonate as well as citric acid used in other centers which have no such problems

Please be more descriptive as to which tubes you are attempting to describe as there are many different interpretations. Being more descriptive can help us help you better.

I'm talking about dialysis pathways, dialyzer input and output. I have pictures but can't upload them. The hoses themselves are cracked to the couplings and to the inlet and outlet of the machine.

Order a PM kit and replace them. You say these machines "have been used a bit". If the silicone tubing has been exposed to high heat (storage), the silicone tubing will 'dry' out and start to crack. The PM kit contains new tubing so replace both the dialysate coupling tubing and the concentrate wand tubing.
